FastChat vs FasterTransformer
A side-by-side comparison of two LLM Inference AI agents — to help you pick the right one.
FastChat
FastChat is an open-source platform for serving and interacting with multiple large language models (LLMs) efficiently. It provides a distributed serving system with a web-based UI and OpenAI-compatible RESTful APIs, enabling seamless integration with existing workflows.
FasterTransformer
FasterTransformer is an open-source library developed by NVIDIA for accelerating transformer-based large language model (LLM) inference. It provides highly optimized implementations for popular transformer architectures, enabling faster and more efficient deployment of LLMs. The project has transitioned to TensorRT-LLM, which builds upon its optimizations.
