Overview
Pattern for deploying LLMs as OpenAI-compatible REST API servers using the vLLM serving framework on Intel XPU.
Description
Online API Serving exposes a loaded LLM as an OpenAI-compatible HTTP API (supporting /v1/completions and /v1/chat/completions endpoints). IPEX-LLM provides its own entrypoint module that wraps vLLM's OpenAI API server with Intel XPU optimizations. The server handles concurrent requests with continuous batching, token streaming, and tensor parallelism for multi-GPU deployment.
Usage
Use this when deploying LLMs as production services that need to serve multiple concurrent users. The OpenAI-compatible API allows drop-in replacement for applications built against the OpenAI API.
Practical Guide
- Configure environment variables (SYCL, oneCCL, VLLM settings)
- Launch the API server with model path and serving parameters
- Server exposes OpenAI-compatible endpoints on configured port
- Clients use standard OpenAI SDK or HTTP requests to interact
