Opus 5.5 Cracks 1800-Line Reverse-Engineering Task After 100+ Agent-Hours of Work
banteg · x · 2026-09-28
Developer banteg reports that Opus 5.5 solved the 1800-line playerupdate function in his crimsonland game decompilation project, which has seen over 100 agent-hours of work since July — including 50 hours by gpt-5.6-sol, 20 by gpt-6-astra, and 36 by opus 5.5. He notes the model was unusually rigorous, even decompiling the compiler to get there, and shows more creative solutions when cornered, with a deliberate, scientific approach that exhausted every theory.
