Long-horizon post-training technique: ultra granular program generation
tokenbender · x · 2026-08-20
The author shares a technique for long-horizon post-training that feels like cheating: "ultra granular program generation."
Core Methodology:
- Use pass@128 to generate multiple attempts.
- Bucketize the failure cases.
- Perform ultra granular verification.
Effect: This approach is indistinguishable from accurately assigning credit to chunks of a long-horizon workflow, solving a limitation of current policy gradient algorithms.
