What the Leaked ChatGPT 5.6 Model Reveals About OpenAI’s Next Move
TL;DR
Rumors around OpenAI's GPT-5.6 are intensifying, with reported gains in multimodal capabilities and token efficiency. A leaked framework called the Mythos Benchmark, used to test models on practical tasks, has also surfaced. Nothing is official yet, but the signals suggest OpenAI is lining up its next move — and reveal how the industry now measures what makes a model good.
Nauti's Take
If the leaks hold up, GPT-5.6's reported gains in multimodality and token efficiency are a genuine opportunity — lower costs and more room for developers to build. The catch: these are still rumors, and benchmarks like Mythos say little about real-world value.
Nauti would wait for official releases and test models on actual tasks rather than chase leak hype.
