Introducing AutoRound: Intel’s Advanced Quantization for LLMs and VLMs

AutoRound is Intel's weight-only post-training quantization that uses signed gradient descent to jointly optimize weight rounding and clipping for accurate low-bit quantization (INT2–INT8). It claims up to 2.1x higher relative accuracy at 2-bit, quantizes a 72B model in ~37 minutes on A100, and supports mixed-bit tuning, multiple export formats, and recipes (auto-round-best/light) with small calibration sets.
