Unsloth publishes Dynamic 3.0 GGUFs with a new held-out divergence metric and the calibration imatrix released for inspection

Sources: Unsloth documentation, HN discussion
Summary: Unsloth documents Dynamic 3.0 GGUF quantization as a pure post-training method, with no fine-tuning or retraining step. The calibration importance matrix is published for inspection rather than described. Accuracy is reported through a divergence metric scored on prompts held out of the calibration set.
Why it matters: The quantization is pure post-training, the calibration data is published rather than described, and the new metric is scored on prompts held out of calibration, so the accuracy claim is checkable rather than asserted.
