flint-opus-step40
Step-40 checkpoint of AlexWortega/flint-opus-curriculum-20261026: a fresh attention-only LoRA (r16/alpha32, q/k/v/o)
on RecursiveSI/flint @ 2a247be, trained with group-relative RL on
antislop tweet continuations graded by an Opus 5.5 judge (astra4 calibrated-v1 reward). Step 40 was the best held-out
antislop point of a 200-step run; later steps regressed.
| held-out (Opus 5.5 judge, 24 prompts each) | base flint | step 40 |
|---|---|---|
| antislop q (0-10) | 4.92 | 5.90 |
| antislop calibrated reward | 0.12 | 0.31 |
| roleplay q (0-10) | 6.38 | 6.13 |
| roleplay calibrated reward | 0.63 | 0.51 |
Small eval sets (n=24) and a single judge: treat these as noisy. Roleplay was not trained before step 101 and is
slightly lower at step 40. The LoRA is folded into the attention weights as W + (B @ A) * alpha / r
(fp32, cast back to bf16), identical to the weights the policy server used during training. Experts are untouched.
