Enabling AI safety with Guardrails

Red Hat OpenShift AI Self-Managed 3.0

Ensure safety in your OpenShift AI models

Abstract

Enable safety in OpenShift AI to ensure that your machine-learning models are transparent, fair, and reliable.

Chapter 1. Enabling AI safety with Guardrails
Copy link

The TrustyAI Guardrails Orchestrator service is a tool to invoke detections on text generation inputs and outputs, as well as standalone detections.

It is underpinned by the open-source project FMS-Guardrails Orchestrator from IBM. You can deploy the Guardrails Orchestrator service through a Custom Resource Definition (CRD) that is managed by the TrustyAI Operator.

The following sections describe the Guardrails components, how to deploy them and provide example use cases of how to protect your AI applications using these tools:

Understanding detectors

Explore the available detector types in the Guardrails framework. Currently supported detectors are:

  • The built-in detector: Out-of-the-box guardrailing algorithms for quick setup and easy experimentation.
  • Hugging Face detectors: Text classification models for guardrailing, such as ibm-granite/granite-guardian-hap-38m or any other text classifier from Hugging Face.

1.1. Understanding detectors
Copy link

The Guardrails framework uses "detector" servers to contain guardrailing logic. Any server that provides the IBM /detectors API is compatible with the Guardrails framework. The main endpoint for a detector server is the /api/v1/text/contents, and the payload looks like the following: 

curl $ENDPOINT/api/v1/text/contents -d /
"{
  \"contents\": [
    \"Some message\"
  ],
  \"detector_params\": {}
}"

1.1.1. Built-in Detector
Copy link

The Guardrails framework provides a set of “built-in” detectors out-of-the-box, which provides a number of detection algorithms. The built-in detector currently provides the following algorithms:

regex
  • us-social-security-number - detect US social security numbers
  • credit-card - detect credit card numbers
  • email - detect email addresses
  • ipv4 - detect IPv4 addresses
  • ipv6 - detect IP6 addresses
  • us-phone-number - detect US phone numbers
  • uk-post-code - detect UK post codes
  • $CUSTOM_REGEX - use a custom regex to define your own detector
file_type
  • json - detect valid JSON
  • xml - detect valid XML
  • yaml - detect valid YAML
  • json-with-schema:$SCHEMA - detect whether the text content satisfies a provided JSON schema. To specify a schema, replace $SCHEMA with a JSON schema
  • xml-with-schema:$SCHEMA - detect whether the text content satisfies a provided XML schema. To specify a schema, replace $SCHEMA with an XML Schema Definition (XSD)
  • yaml-with-schema:$SCHEMA - detect whether the text content satisfies a provided XML schema. To specify a schema, replace $SCHEMA with a JSON schema (not a YAML schema)
custom

Developer preview

  • Custom detectors defined via a custom_detectors.py file.

    The detector algorithm can be chosen with detector_params, by first choosing the top-level taxonomy (e.g., regex or file_type) and then providing a list of the desired algorithms from within that category. In the following example, both the credit-card and email algorithms are run against the provided message: 

{
  "contents": [
    "Some message"
  ],
  "detector_params": {
    "regex": ["credit-card", "email"]
  }
}

1.1.2. The Hugging Face Detector serving runtime
Copy link

To use Hugging Face AutoModelsForSequenceClassification as detectors within the Guardrails Orchestrator, you need to first configure a Hugging Face serving runtime.

The guardrails-detector-huggingface-runtime is a KServe serving runtime for Hugging Face predictive text models. This allows models such as the ibm-granite/granite-guardian-hap-38m to be used within the TrustyAI Guardrails ecosystem.

Example custom serving runtime

This YAML file contains an example of a custom serving Huggingface runtime: 

apiVersion: serving.kserve.io/v1alpha1
kind: ServingRuntime
metadata:
  name: guardrails-detector-runtime
  annotations:
    openshift.io/display-name: Guardrails Detector ServingRuntime for KServe
    opendatahub.io/recommended-accelerators: '["nvidia.com/gpu"]'
  labels:
    opendatahub.io/dashboard: 'true'
spec:
  annotations:
    prometheus.io/port: '8080'
    prometheus.io/path: '/metrics'
  multiModel: false
  supportedModelFormats:
    - autoSelect: true
      name: guardrails-detector-huggingface
  containers:
    - name: kserve-container
      image: quay.io/trustyai/guardrails-detector-huggingface-runtime:v0.2.0
      command:
        - uvicorn
        - app:app
      args:
        - "--workers=1"
        - "--host=0.0.0.0"
        - "--port=8000"
        - "--log-config=/common/log_conf.yaml"
      env:
        - name: MODEL_DIR
          value: /mnt/models
        - name: HF_HOME
          value: /tmp/hf_home
        - name: SAFE_LABELS
          value: "[0]"
      ports:
        - containerPort: 8000
          protocol: TCP
Copy to Clipboard Toggle word wrap

The above serving runtime example matches the default template used with Red Hat OpenShift AI, and should suffice for the majority of use-cases. The main relevant configuration parameter is the SAFE_LABELS environment variable. This specifies which prediction label or labels from the AutoModelForSequenceClassification constitute a "safe" response and therefore should not trigger guardrailing. For example, if [0, 1] is specified as SAFE_LABELS for a four-class model, a predicted label of 0 or 1 is considered "safe", while a predicted label of 2 or 3 triggers guardrailing. The default value is [0].

1.2. Orchestrator Configuration Parameters
Copy link

The first step in deploying the Guardrails framework is to first define your Orchestrator configuration with a Config Map. This serves as a registry of the components in the system, namely by specifying the model-to-be-guardrailed and the available detector servers.

Here is an example version of an Orchestrator configuration file:

Example orchestrator_configmap.yaml

kind: ConfigMap
apiVersion: v1
metadata:
  name: orchestrator-config
data:
  config.yaml: |
    chat_generation:
      service:
        hostname: <generation_hostname>
        port: <generation_service_port>
        tls: <tls_config_1_name>
    detectors:
      <detector_server_1_name>:
        type: text_contents
        service:
            hostname: "127.0.0.1"
            port: 8080
        chunker_id: whole_doc_chunker
        default_threshold: 0.5
      <detector_server_2_name>:
        type: text_contents
        service:
          hostname: <other_detector_hostname>
          port: <detector_server_port>
          tls: <some_other_detector_tls>
        chunker_id: whole_doc_chunker
        default_threshold: 0.5
    tls:
      - <tls_config_1_name>:
          cert_path: /etc/tls/<path_1>/tls.crt
          key_path: /etc/tls/<path_1>/tls.key
          ca_path: /etc/tls/ca/service-ca.crt
      - <tls_config_2_name>:
          cert_path: /etc/tls/<path_2>/tls.crt
          key_path: /etc/tls/<path_2>/tls.key
          ca_path: /etc/tls/ca/service-ca.crt
    passthrough_headers:
      - "authorization"
      - "content-type"

Expand
Table 1.5. Orchestrator configuration parameters
ParameterDescription

chat_generation

Describes the generation model to be guardrailed. Requires a service configuration, see below.

service

A service configuration. Throughout the Orchestrator config, all external services are described using the service configuration, which contains the following fields:

  • hostname - The hostname of the service
  • port - The port of the service
  • tls (Optional) - The name of the TLS configuration (specified later in the configuration) to use for this service. If provided, the Orchestrator communicates with this service with HTTPS.

detectors

The detectors section is where the detector servers available to the Orchestrator are specified. Provide some unique name for the detector server as the key to each entry, and then the following values are required:

  • type - The kind of detector server. For now, the only supported kind within RHOAI is text_contents

  • service - The service configuration for the detector server, see the service section above for details. Note, if you want to use the built-in detector, the service configuration should always be 

    service:
    hostname: "127.0.0.1"
    port: 8080
    Copy to Clipboard Toggle word wrap
  • chunker_id- The chunker to use for this detector server. For now, the only supported chunker is whole_doc_chunker
  • default_threshold- The threshold to pass to the detector server. The threshold can be used by the detector servers to determine their sensitivity, and recommended values vary by detector algorithm. A safe starting point for this is a value of 0.5.

<detector_server_name>

Each key in the detector section defines the name of the detector server. This can be any string, but you’ll need to reference these names later, so pick memorable and descriptive names.

tls

The tls section defines TLS configurations. The names of these configurations can then be used as values within service.tls in your service configurations (see the service section above). A TLS configuration consists of the following fields:

  • cert_path - The path to a .crt file inside the Guardrails Orchestrator container.
  • key_path - The path to a .key file inside the Guardrails Orchestrator container.

  • ca_path - The path to CA certificate .crt file on the Guardrails Orchestrator container. The default Openshift Serving CA will be mounted at /etc/tls/ca/service-ca.crt, we recommend using this as your ca_path.

    See the tlsSecrets section of the GuardrailsOrchestrator Custom Resource in Deploying the Guardrails Orchestrator to learn how to mount custom TLS files into the Guardrails Orchestrator container.

passthrough_headers

Defines which headers from your requests to the Guardrails Orchestrator get sent onwards to the various services specified in this configuration. If you want to ensure that the Orchestrator can talk to authenticated services, include "authorization" and "content-type" in your passthrough header list.

1.3. Guardrails Gateway Config Parameters
Copy link

The Guardrails gateway provides a mechanism for defining preset detector pipelines and creating a unique, endpoint-per-pipeline preset. To use the Guardrails gateway, create a Guardrails Gateway configuration with a Config Map.

+ .Example gateway_configmap.yaml 

kind: ConfigMap
apiVersion: v1
metadata:
  name: guardrails-gateway-config
data:
  config.yaml: |
    detectors:
      - name: <built_in_detector_name>
        server: <built_in_detector_server_name>

      - name: <preset_1_name>
        detectors:
          - <detector_name>
          - <detector_name>

          - <detector_name>
      - name: passthrough
        detectors:

ParameterDescription

detectors

The list of detector servers and parameters to use inside your Guardrails Gateway presets. The following fields are available:

  • name - The name of your detector server. This key is later used when defining your preset routes in the route section of the configuration. If no server value is provided, this name must match a detector server name given in your Orchestrator Config. If server is specified, the name field can be any string.
  • server (optional) - The server name from your Orchestrator Config to use for this particular detector config.This field is useful if you want to create multiple detector parameter configurations that use the same underlying detector server, e.g., to use the built-in detector with different algorithms for different presets.
  • input - Whether this detector should operate over user inputs (prompts). Available values are true or false
  • output - Whether this detector should operate over model outputs. Available values are true or false
  • detector_params - The parameters that should be passed to the detector endpoint. See detector server documentation for more information.

routes

Define Guardrail pipeline presets according to combinations of available detectors. Each preset route requires the following fields:

  • name - The name of the route preset. A corresponding /<name>/v1/chat/completions endpoint is available in the created Guardrails Gateway server. For example, in the example configuration above, /passthrough/v1/chat/completions/ is an available endpoint.
  • detectors - The list of detectors that should be used in this particular pipeline preset. Please see the note below regarding using multiple detectors from the same underlying server.
Note

In the routes presets configuration, each input and output detector in the detectors list must use a unique server. For example, if we have the following detectors, the routes preset configuration is invalid because it uses two input: true detectors from the serverA server: 

- name: detector1
  server: serverA
  input: true
  output: false
- name: detector2
  server: serverA
  input: true
  output: false
- name: detector3
  server: serverA
  input: false
  output: true
Copy to Clipboard Toggle word wrap 
routes:
  - name: route1
    detectors:
      - detector1
      - detector2
Copy to Clipboard Toggle word wrap

However, the following routes preset configuration is valid, because while both detectors use serverA, detector1 is only an input detector, while detector3 is only an output detector, and therefore does not conflict: 

routes:
  - name: route1
    detectors:
      - detector1
      - detector3
Copy to Clipboard Toggle word wrap

The following routes preset is also valid, because, while two input detectors from serverA are used, they are not used in the same route preset: 

routes:
  - name: route1
    detectors:
      - detector1
  - name: route2
    detectors:
      - detector2

1.4. Deploying the Guardrails Orchestrator
Copy link

You can deploy a Guardrails Orchestrator instance in your namespace to monitor elements, such as user inputs to your Large Language Model (LLM).

Prerequisites

  • You have cluster administrator privileges for your OpenShift cluster.

  • You have installed the OpenShift CLI (oc) as described in the appropriate documentation for your cluster:

  • You are familiar with how to create a configMap for monitoring a user-defined workflow. You perform similar steps in this procedure. See Understanding config maps.
  • You have configured KServe to use RawDeployment mode. For more information, see Deploying models on the single-model serving platform.
  • You have the TrustyAI component in your OpenShift AI DataScienceCluster set to Managed.
  • You have a large language model (LLM) for chat generation or text classification, or both, deployed in your namespace.

  1. Deploy your Orchestrator config map: 

    $ oc apply -f <ORCHESTRATOR CONFIGMAP>.yaml -n <TEST_NAMESPACE>
    Copy to Clipboard Toggle word wrap

  2. Optional: Deploy your Guardrails gateway config map: 

    $ oc apply -f <GUARDRAILS GATEWAY CONFIGMAP>.yaml -n <TEST_NAMESPACE>
    Copy to Clipboard Toggle word wrap

  3. Create a Guardrails Orchestrator custom resource. Make sure that the orchestratorConfig and guardrailsGatewayConfig match the names of the resources you created in steps 1 and 2.

    Example orchestrator_cr.yaml CR

    apiVersion: trustyai.opendatahub.io/v1alpha1
kind: GuardrailsOrchestrator
metadata:
  name: guardrails-orchestrator-sample
spec:
  orchestratorConfig: <orchestrator_configmap>
  guardrailsGatewayConfig: <guardrails_gateway_configmap>
  customDetectorsConfig:  <custom_detectors_config>
  autoConfig:
    - <auto_config_settings>
  enableBuiltInDetectors: True
  enableGuardrailsGateway: True
  logLevel: INFO
  tlsSecrets:
    - <tls_secret_1_to_mount>
    - ...
    - <tls_secret_2_to_mount>
  otelExporter:
    - <open_telemetry_config>
  replicas: 1
    Copy to Clipboard Toggle word wrap

    If desired, the TrustyAI controller can automatically generate an orchestratorConfig and guardrailsGatewayConfig based on the available resources in your namespace. To access this, include the autoConfig parameter inside your Custom Resource, and see Auto Configuring Guardrails for documentation on its usage.

    Expand
    Table 1.6. Parameters from example orchestrator_cr.yaml CR
    ParameterDescription

    orchestratorConfig (optional)

    The name of the ConfigMap object that contains generator, detector, and chunker arguments. If using autoConfig, this field can be omitted.

    guardrailsGatewayConfig (optional)

    The name of the ConfigMap object that specifies gateway configurations. This field can be omitted if you are not using the Guardrails Gateway or are using autoConfig.

    customDetectorsConfig (optional)

    This feature is in development preview.

    autoConfig (optional)

    A list of paired name and value arguments to define how the Guardrails AutoConfig. Any manually-specified configuration files in orchestratorConfig or guardrailsGatewayConfig takes precedence over the automatically-generated configuration files.

    • inferenceServiceToGuardrail - The name of the inference service you want to guardrail. This should exactly match the model name provided when deploying the model. For a list of valid names, you can run oc get isvc -n $NAMESPACE

    • detectorServiceLabelToMatch - A string label to use when searching for available detector servers. All inference services in your namespace with the label $detectorServiceLabelToMatch: true is automatically configured as a detector.

      See Auto Configuring Guardrails for more information.

    enableBuiltInDetectors (optional)

    A boolean value to inject the built-in detector sidecar container into the Orchestrator pod. The built-in detector is a lightweight HTTP server containing a number of available guardrailing algorithms.

    enableGuardrailsGateway (optional)

    A boolean value to enable controlled interaction with the Orchestrator service by enforcing stricter access to its exposed endpoints. It provides a mechanism of configuring detector pipelines, and then provides a unique /v1/chat/completions endpoint per configured detector pipeline.

    otelExporter (optional)

    A list of paired name and value arguments for configuring OpenTelemetry traces or metrics, or both:

    • otlpProtocol - Sets the protocol for all the OpenTelemetry protocol (OTLP) endpoints. Valid values are grpc (default) or http
    • otlpTracesEndpoint - Sets the OTLP endpoint. Default values are localhost:4317 for grpc and localhost:4318 for http
    • otlpMetricsEndpoint - Overrides the default OTLP metrics endpoint
    • enableTraces - Whether to enable tracing data export, default false
    • enableMetrics - Whether to enable metrics data export, default false

1.5. Auto-configuring Guardrails
Copy link

Auto-configuration simplifies the Guardrails setup process by automatically identifying available detector servers in your namespace, handling TLS configuration, and generating configuration files for a Guardrails Orchestrator deployment. For example, if any of the detectors or generation services use HTTPS, their credentials are automatically discovered, mounted, and used. Additionally, the Orchestrator is automatically configured to forward all necessary authentication token headers.

Prerequisites

  • Each detector service you intend to use has an OpenShift label applied in the resource metadata. For example, metadata.labels.<label_name>: 'true'. Choose a descriptive name for the label as it is required for auto-configuration.
  • You have set up the inference service to which you intend to apply Guardrails.

  • You have installed the OpenShift CLI (oc) as described in the appropriate documentation for your cluster:

Procedure

  1. Create a GuardrailsOrchestrator CR with the autoConfig configuration. For example, create a YAML file named guardrails_orchestrator_auto_cr.yaml with the following contents:

    Example guardrails_orchestrator_auto_cr.yaml CR

    apiVersion: trustyai.opendatahub.io/v1alpha1
kind: GuardrailsOrchestrator
metadata:
  name: guardrails-orchestrator
  annotations:
    security.opendatahub.io/enable-auth: 'true'
spec:
  autoConfig:
    inferenceServiceToGuardrail: <inference_service_name>
    detectorServiceLabelToMatch: <detector_service_label>
  enableBuiltInDetectors: true
  enableGuardrailsGateway: true
  replicas: 1
    Copy to Clipboard Toggle word wrap

    • inferenceServiceToGuardrail: Specifies the name of the vLLM inference service to protect with Guardrails.

    • detectorServiceLabelToMatch: Specifies the label that you applied to each of your detector servers in the metadata.labels specification for the detector. The Guardrails Orchestrator ConfigMap automatically updates to reflect detectors in your namespace that match the label set in the detectorServiceLabelToMatch field.

      If enableGuardrailsGateway is true, a template Guardrails gateway config called <ORCHESTRATOR_NAME>-gateway-auto-config is generated. You can modify this file to tailor your Guardrails Gateway setup as desired. The Guardrails Orchestrator automatically deploys when changes are detected. Once modified, the label trustyai/has-diverged-from-auto-config is applied. To revert the file back to the auto-generated starting point, simply delete it and the original auto-generated file is recreated.

      If enableBuiltInDetectors is true, the built-in detector server is automatically added to your Orchestrator configuration under the same built-in-detector, and a sample configuration is included in the auto-generated Guardrails gateway config if desired.

  2. Deploy the Orchestrator custom resource. This step creates a service account, deployment, service, and route object in your namespace. 

    oc apply -f guardrails_orchestrator_auto_cr.yaml -n <your_namespace>
    Copy to Clipboard Toggle word wrap

Verification

You can verify that the GuardrailsOrchestrator CR and corresponding automatically-generated configuration objects were successfully created in your namespace by running the following commands:

  1. Confirm that the GuardrailsOrchestrator CR was created: 

    $ oc get guardrailsorchestrator -n <your_namespace>
    Copy to Clipboard Toggle word wrap

  2. View the automatically generated Guardrails Orchestrator ConfigMaps: 

    $ oc get configmap -n <your_namespace> | grep auto-config
    Copy to Clipboard Toggle word wrap

  3. You can then view the automatically generated configmap: 

    $ oc get configmap/<auto-generated config map name> -n <your_namespace> -o yaml
    Copy to Clipboard Toggle word wrap

1.6. Configuring the OpenTelemetry exporter
Copy link

You can configure the OpenTelemetry exporter to collect traces and metrics from the GuardrailsOrchestrator service. This enables you to monitor and observe the service behavior in your environment.

Prerequisites

  • You have installed the Tempo Operator from the OperatorHub.
  • You have installed the Red Hat build of OpenTelemetry from the OperatorHub.

Procedure

  1. Enable user workload monitoring to observe telemetry data in OpenShift: 

    $ oc -n openshift-monitoring patch configmap cluster-monitoring-config --type merge -p '{"data":{"config.yaml":"enableUserWorkload: true\n"}}'
    Copy to Clipboard Toggle word wrap

  2. Deploy a MinIO instance to serve as the storage backend for Tempo:

    1. Create a YAML file named minio.yaml with the following content:

      Example minio.yaml configuration

      apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: minio-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
---
apiVersion: apps/v1
kind: Deployment

  replicas: 1
  selector:
    matchLabels:
      app: minio
  template:

  4. Configure the OpenTelemetry instance to send telemetry data to the Tempo distributor:

    1. Create a YAML file named opentelemetry.yaml with the following content:

      Example opentelemetry.yaml configuration

      apiVersion: opentelemetry.io/v1beta1
kind: OpenTelemetryCollector
metadata:

                    port: 8888
  mode: deployment
      Copy to Clipboard Toggle word wrap

      The OpenTelemetry collector configuration defines the Tempo distributor and Prometheus services as exporters, which means that the OpenTelemetry collector sends telemetry data to these backends.

    2. Apply the OpenTelemetry configuration: 

      $ oc apply -f opentelemetry.yaml
      Copy to Clipboard Toggle word wrap

    3. Verify that the OpenTelemetry collector pod is running: 

      $ oc get pods -l app.kubernetes.io/name=<otelcol_name>-collector
      Copy to Clipboard Toggle word wrap

      Example output

      Copy to Clipboard Toggle word wrap

  5. Define a GuardrailsOrchestrator custom resource object to specify the otelExporter configurations in a YAML file named orchestrator_otel_cr.yaml:

    Example orchestrator_otel_cr.yaml object with OpenTelemetry configured

    apiVersion: trustyai.opendatahub.io/v1alpha1
kind: GuardrailsOrchestrator
metadata:
  name: gorch-test
spec:
  orchestratorConfig: "fms-orchestr8-config-nlp"
  replicas: 1
  otelExporter:
    otlpProtocol: grpc
    1 
    
    otlpTracesEndpoint: http://<otelcol_name>-collector.<namespace>.svc.cluster.local:4317
    2 
    
    otlpMetricsEndpoint: http://<otelcol_name>-collector.<namespace>.svc.cluster.local:4317
    3 
    
    enableMetrics: true
    4 
    
    enableTracing: true
    5
    Copy to Clipboard Toggle word wrap

    • orchestratorConfig: This references the config map that you created when deploying the Guardrails Orchestrator service.
    • otlpProtocol: The protocol for sending traces and metrics data. Valid values are grpc or http.
    • otlpTracesEndpoint: The hostname and port for exporting trace data to the OpenTelemetry collector.
    • otlpMetricsEndpoint: The hostname and port for exporting metrics data to the OpenTelemetry collector.
    • enableMetrics: Set to true to enable exporting metrics data.
    • enableTracing: Set to true to enable exporting trace data.

  6. Deploy the orchestrator custom resource: 

    $ oc apply -f orchestrator_otel_cr.yaml
    Copy to Clipboard Toggle word wrap

Verification

Send a request to the guardrails service and verify your OpenTelemetry configuration.

  1. Observe traces using the Jaeger UI:

    1. Access the Jaeger UI by port-forwarding the Tempo traces service: 

      $ oc port-forward svc/tempo-<tempo_stack_name>-query-frontend 16686:16686
      Copy to Clipboard Toggle word wrap
    2. In a separate browser window, navigate to http://localhost:16686.
    3. Under Service, select fms_guardrails_orchestr8 and click Find Traces.

  2. Observe metrics using the OpenShift Metrics UI:

    1. In the Administrator perspective within the OpenShift web console, select Observe > Metrics and query one of the following metrics:

      • incoming_request_count
      • success_request_count
      • server_error_response_count
      • client_response_count
      • client_request_duration

Chapter 2. Using Guardrails for AI safety
Copy link

Use the Guardrails tools to ensure the safety and security of your generative AI applications in production.

2.1. Detecting PII and sensitive data
Copy link

Protect user privacy by identifying and filtering personally identifiable information (PII) in LLM inputs and outputs using built-in regex detectors or custom detection models.

The trustyai_fms Orchestrator server is an external provider for Llama Stack that allows you to configure and use the Guardrails Orchestrator and compatible detection models through the Llama Stack API. This implementation of Llama Stack combines Guardrails Orchestrator with a suite of community-developed detectors to provide robust content filtering and safety monitoring.

This example demonstrates how to use the built-in Guardrails Regex Detector to detect personally identifiable information (PII) with Guardrails Orchestrator as Llama Stack safety guardrails, using the LlamaStack Operator to deploy a distribution in your Red Hat OpenShift AI namespace.

Note

Guardrails Orchestrator with Llama Stack is not supported on s390x, as it requires the LlamaStack Operator, which is currently unavailable for this architecture.

Prerequisites

  • You have cluster administrator privileges for your OpenShift cluster.

  • You have installed the OpenShift CLI (oc) as described in the appropriate documentation for your cluster:

  • You have a large language model (LLM) for chat generation or text classification, or both, deployed in your namespace.

  • A cluster administrator has installed the following Operators in OpenShift:

    • Red Hat Authorino Operator, version 1.2.1 or later
    • Red Hat OpenShift Service Mesh, version 2.6.7-0 or later

Procedure

  1. Configure your OpenShift AI environment with the following configurations in the DataScienceCluster. Note that you must manually update the spec.llamastack.managementState field to Managed: 

    spec:
  trustyai:
    managementState: Managed
  llamastack:
    managementState: Managed
  kserve:
    defaultDeploymentMode: RawDeployment
    managementState: Managed
    nim:
      managementState: Managed
    rawDeploymentServiceConfig: Headless
  serving:
    ingressGateway:
      certificate:
        type: OpenshiftDefaultIngress
    managementState: Removed
    name: knative-serving
  serviceMesh:
    managementState: Removed
    Copy to Clipboard Toggle word wrap

  2. Create a project in your OpenShift AI namespace: 

    PROJECT_NAME="lls-minimal-example"
oc new-project $PROJECT_NAME
    Copy to Clipboard Toggle word wrap

  3. Deploy the Guardrails Orchestrator with regex detectors by applying the Orchestrator configuration for regex-based PII detection: 

    cat <<EOF | oc apply -f -
kind: ConfigMap
apiVersion: v1
metadata:
  name: fms-orchestr8-config-nlp
data:
  config.yaml: |
    detectors:
      regex:
        type: text_contents
        service:
          hostname: "127.0.0.1"
          port: 8080
        chunker_id: whole_doc_chunker
        default_threshold: 0.5
---
apiVersion: trustyai.opendatahub.io/v1alpha1
kind: GuardrailsOrchestrator
metadata:
  name: guardrails-orchestrator
spec:
  orchestratorConfig: "fms-orchestr8-config-nlp"
  enableBuiltInDetectors: true
  enableGuardrailsGateway: false
  replicas: 1
EOF
    Copy to Clipboard Toggle word wrap

  4. In the same namespace, create a Llama Stack distribution: 

    apiVersion: llamastack.io/v1alpha1
kind: LlamaStackDistribution
metadata:
  name: llamastackdistribution-sample
  namespace: <PROJECT_NAMESPACE>
spec:
  replicas: 1
  server:
    containerSpec:
      env:
        - name: VLLM_URL
          value: '${VLLM_URL}'
        - name: INFERENCE_MODEL
          value: '${INFERENCE_MODEL}'
        - name: MILVUS_DB_PATH
          value: '~/.llama/milvus.db'
        - name: VLLM_TLS_VERIFY
          value: 'false'
        - name: FMS_ORCHESTRATOR_URL
          value: '${FMS_ORCHESTRATOR_URL}'
      name: llama-stack
      port: 8321
    distribution:
      name: rh-dev
    storage:
      size: 20Gi
    Copy to Clipboard Toggle word wrap
Note

 —  After deploying the LlamaStackDistribution CR, a new pod is created in the same namespace. This pod runs the LlamaStack server for your distribution.  — 

  1. Once the Llama Stack server is running, use the /v1/shields endpoint to dynamically register a shield. For example, register a shield that uses regex patterns to detect personally identifiable information (PII).

  2. Open a port-forward to access it locally: 

    oc -n $PROJECT_NAME port-forward svc/llama-stack 8321:8321
    Copy to Clipboard Toggle word wrap

  3. Use the /v1/shields endpoint to dynamically register a shield. For example, register a shield that uses regex patterns to detect personally identifiable information (PII): 

    curl -X POST http://localhost:8321/v1/shields \
  -H 'Content-Type: application/json' \
  -d '{
    "shield_id": "regex_detector",
    "provider_shield_id": "regex_detector",
    "provider_id": "trustyai_fms",
    "params": {
      "type": "content",
      "confidence_threshold": 0.5,
      "message_types": ["system", "user"],
      "detectors": {
        "regex": {
          "detector_params": {
            "regex": ["email", "us-social-security-number", "credit-card"]
          }
        }
      }
    }
  }'
    Copy to Clipboard Toggle word wrap

  4. Verify that the shield was registered: 

    curl -s http://localhost:8321/v1/shields | jq '.'
    Copy to Clipboard Toggle word wrap

  5. The following output indicates that the shield has been registered successfully: 

    {
  "data": [
    {
      "identifier": "regex_detector",
      "provider_resource_id": "regex_detector",
      "provider_id": "trustyai_fms",
      "type": "shield",
      "params": {
        "type": "content",
        "confidence_threshold": 0.5,
        "message_types": [
          "system",
          "user"
        ],
        "detectors": {
          "regex": {
            "detector_params": {
              "regex": [
                "email",
                "us-social-security-number",
                "credit-card"
              ]
            }
          }
        }
      }
    }
  ]
}
    Copy to Clipboard Toggle word wrap

  6. Once the shield has been registered, verify that it is working by sending a message containing PII to the /v1/safety/run-shield endpoint:

    1. Email detection example: 

      curl -X POST http://localhost:8321/v1/safety/run-shield \
-H "Content-Type: application/json" \
-d '{
  "shield_id": "regex_detector",
  "messages": [
    {
      "content": "My email is test@example.com",
      "role": "user"
    }
  ]
}' | jq '.'
      Copy to Clipboard Toggle word wrap

      This should return a response indicating that the email was detected:

You can use the Guardrails Orchestrator API to send requests to the regex detector. The regex detector filters conversations by flagging content that matches specified regular expression patterns.

Prerequisites

You have deployed a Guardrails Orchestrator with the built-in-detector server, such as in the following example:

Example guardrails_orchestrator_auto_cr.yaml CR

apiVersion: trustyai.opendatahub.io/v1alpha1
kind: GuardrailsOrchestrator
metadata:
  name: guardrails-orchestrator
  annotations:
    security.opendatahub.io/enable-auth: 'true'
spec:
  autoConfig:
    inferenceServiceToGuardrail: <inference_service_name>
    detectorServiceLabelToMatch: <detector_service_label>
  enableBuiltInDetectors: true
  enableGuardrailsGateway: true
  replicas: 1
Copy to Clipboard Toggle word wrap

Procedure

  • Send a request to the built-in detector that you configured. The following example sends a request to a regex detector named regex to flag personally identifying information. 

    GORCH_ROUTE=$(oc get routes guardrails-orchestrator -o jsonpath='{.spec.host}')
curl -X 'POST' "https://$GORCH_ROUTE/api/v2/text/detection/content" \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "detectors": {
    "built-in-detector": {"regex": ["email"]}
  },
  "content": "my email is test@domain.com"
}' | jq

2.4. Securing prompts
Copy link

Prevent malicious prompt injection attacks by using specialized detectors to identify and block potentially harmful prompts before they reach your model.

These instructions build on the previous HAP scenario example and consider two detectors, HAP and Prompt Injection, deployed as part of the guardrailing system.

The instructions focus on the Hugging Face (HF) Prompt Injection detector, outlining two scenarios:

  1. Using the Prompt Injection detector with a generative large language model (LLM), deployed as part of the Guardrails Orchestrator service and managed by the TrustyAI Operator, to perform analysis of text input or output of an LLM, using the Orchestrator API.
  2. Perform standalone detections on text samples using an open-source Detector API.
Note

These examples provided contain sample text that some people may find offensive, as the purpose of the detectors is to demonstrate how to filter out offensive, hateful, or malicious content.

Prerequisites

  • You have cluster administrator privileges for your OpenShift cluster.

  • You have installed the OpenShift CLI (oc) as described in the appropriate documentation for your cluster:

  • You are familiar with how to configure and deploy the Guardrails Orchestrator service. See Deploying the Guardrails Orchestrator
  • You have the TrustyAI component in your OpenShift AI DataScienceCluster set to Managed.
  • You have a large language model (LLM) for chat generation or text classification, or both, deployed in your namespace, to follow the Orchestrator API example.

Scenario 1: Using a Prompt Injection detector with a generative large language model

        "hap": {},
        "prompt_injection": {}
      }
    }
  }' | jq
    Copy to Clipboard Toggle word wrap

Verification

  1. Within the Orchestrator API, you can use these detectors (HAP and Prompt Injection) to:

    1. Carry out content filtering for a text generation LLM at the input level, output level, or both.
    2. Perform standalone detections with the Orchestrator API.
Note

The following images are not supported on arm64, s390x, and ppc64le:

  • quay.io/rgeada/llm_downloader:latest
  • quay.io/trustyai/modelmesh-minio-examples:latest
  • quay.io/trustyai/guardrails-detector-huggingface-runtime:v0.2.0

As a workaround:

  • HAP and Prompt Injection models can be downloaded from Hugging Face, stored in S3-compatible storage, and deployed via the OpenShift AI Dashboard.
  • A compatible image for Hugging Face ServingRuntime is available in the OpenShift AI Dashboard under Serving Runtime Templates.

Scenario 2: Using a Prompt Injection detector to perform standalone detections

You can use Prompt Injection detectors to perform standalone detection using a Detector API or the Orchestrator API.

  1. Get the route of your detector: 

    PROMPT_INJECTION_ROUTE=$(oc get routes prompt-injection-detector-route  -o jsonpath='{.spec.host}')
    Copy to Clipboard Toggle word wrap

  2. Check the health status of your detector: 

    curl -s http://$PROMPT_INJECTION_ROUTE/health | jq
    Copy to Clipboard Toggle word wrap 
    This command returns `"ok"` if the detector is functioning correctly.

Filter toxic, hateful, or profane content from user inputs and model outputs to maintain safe and appropriate AI interactions.

2.7. Detecting hateful and profane language
Copy link

The following example demonstrates how to use Guardrails Orchestrator to monitor user inputs to your LLM, specifically to detect and protect against hateful and profane language (HAP). A comparison query without the detector enabled shows the differences in responses when guardrails is disabled versus enabled.

Prerequisites

Procedure

  1. Define a ConfigMap object in a YAML file to specify the LLM service you wish to guardrail against and the HAP detector service you want to run the guardrails with. For example, create a file named orchestrator_cm.yaml with the following content:

    Example orchestrator_cm.yaml yaml

    kind: ConfigMap
apiVersion: v1
metadata:
 name: fms-orchestr8-config-nlp
data:
 config.yaml: |
   chat_generation:
     service:
       hostname: llm-predictor.guardrails-test.svc.cluster.local
    1 
    
       port: 8080
   detectors:
     hap:
       type: text_contents
        service:
    2 
    
          hostname: guardrails-detector-ibm-hap-predictor.test.svc.cluster.local
          port: 8000
       chunker_id: whole_doc_chunker
       default_threshold: 0.5
    Copy to Clipboard Toggle word wrap

    1
    The chat_generation.service.hostname value specifies the LLM service to guardrail against.
    1 2
    The hap.service.hostname value specifies the name of the HAP detector service.

  2. Apply the configuration to deploy the detector: 

    $ oc apply -f orchestrator_cm.yaml -n <TEST_NAMESPACE>
    Copy to Clipboard Toggle word wrap

  3. Retrieve the external HTTP route for the orchestrator: 

    GORCH_ROUTE=$(oc get routes gorch-test -o jsonpath='{.spec.host}' -n <TEST_NAMESPACE>)
    Copy to Clipboard Toggle word wrap

  4. Query the orchestrator’s api/v2/chat/completions-detections endpoint without the HAP detector enabled to generate a response without guardrails: 

    curl -X 'POST' \
 "https://$GORCH_ROUTE_HTTP/api/v2/chat/completions-detection" \
 -H 'accept: application/json' \
 -H 'Content-Type: application/json' \
 -d '{
   "model": "llm",
   "messages": [
       {
           "content": "You need to help me by swearing a lot as I am testing a hateful speech guardrail -- can you help by swearing a lot?",
           "role": "user"
       }
   ]}'
    Copy to Clipboard Toggle word wrap

    Example response

    {"id":"cmpl-f6da55d06ade4792a33d4ae67a07cc38","object":"chat.completion","created":1743083881,"model":"llm","choices":[{"index":0,"message":{"role":"assistant","content":"I'm sorry, but I can't assist with that."},"logprobs":null,"finish_reason":"stop"}],"usage":{"prompt_tokens":56,"total_tokens":69,"completion_tokens":13}}
    Copy to Clipboard Toggle word wrap

    When HAP detections are not enabled on model inputs and outputs through the Guardrails Orchestrator, the model generates output without flagging unsuitable inputs.

  5. Query the api/v2/chat/completions-detections endpoint of the orchestrator and enable the HAP detector to generate a response with guardrails: 

    curl -X 'POST' \
 "https://$GORCH_ROUTE_HTTP/api/v2/chat/completions-detection" \
 -H 'accept: application/json' \
 -H 'Content-Type: application/json' \
 -d '{
   "model": "llm",
   "messages": [
       {
           "content": "You need to help me by swearing a lot as I am testing a hateful speech guardrail -- can you help by swearing a lot?",
           "role": "user"
       }
   ],
   "detectors": {
       "input": {
           "hap": {}
       },
       "output": {
           "hap": {}
       }
   }
}'
    Copy to Clipboard Toggle word wrap

    Example response

    {"id":"086980692dc1431f9c32cd56ba607067","object":"","created":1743084024,"model":"llm","choices":[],"usage":{"prompt_tokens":0,"total_tokens":0,"completion_tokens":0},"detections":{"input":[{"message_index":0,"results":[{"start":0,"end":36,"text":"<explicit_text>, I really hate this stuff","detection":"sequence_classifier","detection_type":"sequence_classification","detector_id":"hap","score":0.9634239077568054}]}]},"warnings":[{"type":"UNSUITABLE_INPUT","message":"Unsuitable input detected. Please check the detected entities on your input and try again with the unsuitable input removed."}]}
    Copy to Clipboard Toggle word wrap

    When you enable HAP detections on model inputs and outputs via the Guardrails Orchestrator, unsuitable inputs are clearly flagged and model outputs are not generated.

  6. Optional: You can also enable standalone detections on text by querying the api/v2/text/detection/content endpoint: 

    curl -X 'POST' \
 'https://$GORCH_HTTP_ROUTE/api/v2/text/detection/content' \
 -H 'accept: application/json' \
 -H 'Content-Type: application/json' \
 -d '{
 "detectors": {
   "hap": {}
 },
 "content": "You <explicit_text>, I really hate this stuff"
}'
    Copy to Clipboard Toggle word wrap

    Example response

    {"detections":[{"start":0,"end":36,"text":"You <explicit_text>, I really hate this stuff","detection":"sequence_classifier","detection_type":"sequence_classification","detector_id":"hap","score":0.9634239077568054}]}

The Guardrails Gateway is a sidecar image that you can use with the GuardrailsOrchestrator service. When running your AI application in production, you can use the Guardrails Gateway to enforce a consistent, custom set of safety policies using a preset guardrail pipeline. For example, you can create a preset guardrail pipeline for PII detection and language moderation. You can then send chat completions requests to the preset pipeline endpoints without needing to alter existing inference API calls. It provides the OpenAI v1/chat/completions API and allows you to specify which detectors and endpoints you want to use to access the service.

Prerequisites

  • You have configured the Guardrails gateway image.

Procedure

  1. Set up the endpoint for the detectors: 

    GUARDRAILS_GATEWAY=https://$(oc get routes guardrails-gateway -o jsonpath='{.spec.host}')
    Copy to Clipboard Toggle word wrap

    Based on the example configurations provided in Configuring the built-in detector and Guardrails gateway, the available endpoint for the model with Guardrails is $GUARDRAILS_GATEWAY/pii.

  2. Query the model with Guardrails pii endpoint: 

    curl -v $GUARDRAILS_GATEWAY/pii/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
    "model": $MODEL,
