OpenAI may be preparing GPT-5.6, with reports pointing to GPT-5.6, Mini, and Pro variants arriving across ChatGPT, the API, and Pro plans over multiple days.
Early sightings of GPT-5.6 Pro suggest improvements in coding and agentic tasks. Reports also point to a larger 1.5M-token context window, stronger long-horizon coding, and faster Codex performance.
A new voice model, GPT-Bidi-1, is also rumored, enabling simultaneous listening and speaking, interruption handling, and real-time responses.
