Technique: Ultra-Granular Program Generation for Long-Horizon Post-Training

tokenbender · x · 2026-08-20

Shared a technique for long-horizon post-training called 'ultra granular program generation.' By bucketizing failures and generating granular verifiers, it assigns credit to chunks of the workflow accurately, addressing a limitation in current policy gradient algorithms. To prevent reward hacking, the method progressively removes high pass-rate verification units, providing adaptive mitigation.
