VLLM vs. TGI: Which LLM Inference Engine is Best?

The Importance of PagedAttention

vLLM revolutionized LLM serving with PagedAttention, allowing memory to be managed in pages like an OS, drastically reducing memory waste and increasing throughput.

Text Generation Inference (TGI)

Hugging Face's TGI is highly optimized for production, offering robust telemetry, rate limiting, and native support for a vast array of architectures.

The Verdict

Choose vLLM for raw throughput and simplicity. Choose TGI if you are building an enterprise API and need extensive tracing and production readiness.
