A LocalLLaMA user compared the new Jev model from TypeSafe's System One release — which outputs probabilities given choices — with Qwen reranker models, then implemented the approach using Qwen3.5 4B logits.

Trajectory-Shaped Discrete Flow Matching uses a lightweight energy compass to guide training trajectories, letting a 170M-parameter student hit 32% lower perplexity than its 1,024-step teacher at 8 steps — 128× faster. Shaping is training-only, so inference cost is unchanged.

DACA-GRPO adds Denoising Progress Scores and Stratified Masking Likelihood to any GRPO-style trainer, targeting missing temporal credit assignment and mean-field likelihood bias. Gains reach 36.3pp on constraint satisfaction, 7.4pp on code generation, and 5.6pp on math reasoning across seven benchmarks.
