main was replaced on this push. The previous weights are still pinnable at
revision 1cb58df
— a GRPO run on top of digest-sft2, which collapsed into looping identical commit-sha
sections. That card advertised a mean reward of 0.4060 against an sft2 baseline of
0.2634; both came from the superseded scorer at max_new=400 with a repetition penalty
and are not comparable to the numbers above or to each other. Two things changed
underneath it: the training prompts are now diff-aware (they carry file stats and truncated
patches, matching what production git-digest sends, where sft2 only ever saw commit
messages), and reward.py was hardened by adversarial fuzzing and teacher calibration.
Weights: Apache-2.0 (inherited from the base model). Training code: MIT — usr-wwelsh/digest-finetune.
