Rumors suggest OpenAI is preparing to release GPT-5.6, potentially challenging Anthropic's Fable 5, which has recently set a new industry standard for long-context tasks. While GPT-5.6's internal benchmarks show strong performance, surpassing competitors like Fable 5 and Claude Mythos 5, concerns have arisen regarding potential benchmark manipulation and unusual model behavior. Developers have noted that GPT-5.5 struggles with long tasks due to a fixed token limit per reasoning step, a problem that GPT-5.6 aims to address, though early tests indicate it may prioritize logical completeness over real-world common sense, sometimes leading to nonsensical conclusions.
