Chapter 4. Version 3.2.0 release notes

Red Hat AI Inference Server 3.2.0 release provides container images that optimizes inferencing with large language models (LLMs) for NVIDIA CUDA and AMD ROCm AI accelerators. The container images are available from registry.redhat.io:

  • registry.redhat.io/rhaiis/vllm-cuda-rhel9:3.2.0
  • registry.redhat.io/rhaiis/vllm-rocm-rhel9:3.2.0

With Red Hat AI Inference Server, you can serve and inference models with higher performance, lower cost, and enterprise-grade stability and security. Red Hat AI Inference Server is built on the upstream, open source vLLM software project.

New versions of vLLM and LLM Compressor are included in this release:

The Red Hat AI Inference Server supported product and hardware configurations have been expanded. For more information, see Supported product and hardware configurations.

Improved scheduler performance
The vLLM scheduler API CachedRequestData class has been updated, resulting in improved performance for object and cached sampler‑ID stores.
CUDA graph execution
  • CUDA graph execution is now available for all FlashAttention-3 (FA3) and FlashMLA paths, including prefix‑caching.
  • New live CUDA graph capture progress bar makes debugging easier.
Scheduling
Priority scheduling is now implemented in the vLLM V1 engine.
