Jacobian lenses for DeepSeek-V4-Flash (~280B FP8/FP4 MoE, mHC residual), fit on 25 pile
prompts, target_layer=-2 (penultimate), skip_first=4, max_seq_len=128; merged
per-prompt partials from Modal volume jlens-ablations
(outputs/deepseek-v4-flash/<arm>/n25/lens.pt). Layout: <model>/<arm>-n25/lens.pt.
| file | arm | gradient rules |
|---|---|---|
deepseek-v4-flash/j-lens-n25/lens.pt | std | standard gradients — the J-lens baseline |
deepseek-v4-flash/early-lens-all-c4-n25/lens.pt | all-c4 | early-lens: LN-rule + identity-rule + half-rule, routed+shared experts as MLPs, mHC coefficients detached, router frozen, shared-expert grad-scale c=4 — sweep winner |
