Best TensorRT-LLM Alternatives

vLLM is an Apache-2.0 LLM inference and serving engine focused on high-throughput self-hosted model APIs. It combines PagedAttention, continuous batching, prefix caching, quantization options, OpenAI-compatible serving, structured outputs, metrics, Docker/Kubernetes deployment guidance and integrations with agent and LLM frameworks.

SGLang is an open-source serving framework for large language and vision-language models, designed for low latency and high throughput. It features RadixAttention for automatic KV cache reuse, compressed finite state machines for fast structured output generation, continuous batching, and tensor parallelism. With over 25,000 GitHub stars, it supports models like LLaMA, Mistral, Qwen, and Gemma on NVIDIA and AMD GPUs.

Text Generation Inference (TGI) is Hugging Face's production-ready serving framework for large language models. It features flash attention, continuous batching, tensor parallelism, quantization via GPTQ/AWQ/EETQ, and Safetensors support. Powers Hugging Face's Inference API and Inference Endpoints, with an OpenAI-compatible API and Docker deployment. Supports LLaMA, Mistral, Falcon, and other popular model architectures.
