Key Points
- The article evaluates 15 vLLM alternatives for production LLM inference, basing recommendations on real deployment experience rather than benchmarks.
- It details real-world memory challenges with vLLM, including fragmentation under sustained load, long-context memory explosions with 32K+ contexts, and overhead from speculative decoding.
- It outlines hardware support gaps across AMD ROCm, Intel GPUs, Apple Silicon, and CPU-only setups, explaining resulting performance and parity trade-offs.
- It points out quantization gaps for vLLM, noting lack of GGUF and EXL2 support and FP8-related instability on some GPUs.
- It promises practical guidance on when alternatives outperform vLLM, when vLLM remains preferable, and hidden gotchas that documentation often omits.
