Intel's AutoRound is an open-source quantization toolkit achieving high accuracy at 2–4 bit widths with minimal tuning, using sign-gradient descent optimization. The toolkit has been integrated into major inference frameworks including vLLM, Transformers, SGLang, and LLM-Compressor, with continued development including mixed-precision algorithms and block-wise FP8 quantization.
