GPT-6.1 sol out-reverse-engineers Opus 5.5 on a compiled game, at a fraction of the cost

User haider tested GPT-6.1 sol's reverse-engineering chops and came away impressed, especially at the price: he handed it a compiled game with no source code and asked it to figure out how health and inventory worked, then point out where the logic could be patched for a local mod.

The comparison: Opus 5.5 throws up a cybersecurity flag and stalls, while GPT-6.1 sol just keeps working through the task. Notable for its persistence on a low-cost, hands-off reversing workflow.
