 **ATTENTION: AutoFP8 has been deprecated in preference of [`llm-compressor`](https://github.com/vllm-project/llm-compressor), a library for producing all sorts of model compression in addition to FP8. Check out the [FP8 example here](https://github.com/vllm-project/llm-compressor/tree/main/examples/quantization_w8a8_fp8).**

 Open-source FP8 quantization library for producing compressed checkpoints for running in vLLM - see https://github.com/vllm-project/vllm/pull/4332 for details on the implementation for inference. This library focuses on providing quantized weight, activation, and kv cache scales for FP8_E4M3 precision.
