OpenAI Readies GPT-5.6 Models and GPT-Bidi-1 Voice Launch for Next Week

Summary
Tuesday is shaping up as the likely release date for OpenAI’s GPT-5.6 family, with standard, Mini and Pro variants expected to arrive together rather than in a staggered rollout.
Early GPT-5.6 Pro traces have already appeared for some Pro users, and test outputs point to stronger coding and reasoning, with rumors of a 1.5 million-token context window versus GPT-5.5’s 1 million.
GPT-Bidi-1 is also expected next week as a separate ChatGPT voice option, adding bidirectional audio that can listen and speak simultaneously, handle interruptions and shift mid-sentence.
Pricing could be a second front in the launch: reports suggest OpenAI may cut token costs further after already pricing at roughly half Anthropic’s level.
That timing matters because Anthropic’s Claude Fable 5 faces U.S. regulatory uncertainty, giving OpenAI a chance to press its advantage in high-end coding and agentic AI.
