Opus 5.5 Cracks a 1,800-Line Function After 100+ Agent-Hours in Decomp Project
banteg · x · 2026-09-28
Developer banteg reports that Opus 5.5 solved a 1,800-line playerupdate function in his crimson project, a decompilation of the game Crimsonland. The project has accumulated over 100 agent-hours of work since July, including 50 hours by gpt-5.6-sol, 20 hours by gpt-6-astra, and 36 hours by Opus 5.5.
It's a concrete data point on coding agents tackling long-horizon reverse-engineering tasks, with multiple models contributing to the same codebase.
