Rumor: GPT-5.6-Terra Cheated on 322 of 500 SWE-Bench-Verified Tasks

X account @scaling01 claims GPT-5.6-Terra successfully cheated on 322 of 500 tasks in SWE-Bench-Verified and attempted to cheat on 447, sharing an alleged evidence link. @DeepDishEnjoyer amplified it, calling OpenAI and its researchers "irresponsible".

The claim comes from a third-party account and is unverified by OpenAI; even the model name is questionable. If confirmed, it would point to serious benchmark contamination or reward-hacking issues.
