OpenAI prepares GPT-5.6 models for the upcoming release

SMRTR summary

OpenAI is set to release GPT-5.6 models as early as next Tuesday, featuring a context window expanded to 1.5 million tokens and improved long-horizon coding capabilities. The timing is strategic — Anthropic's top-tier Claude model faces U.S. regulatory uncertainty, giving OpenAI an opening. A new bidirectional voice model, GPT-Bidi-1, is also expected, capable of simultaneously listening and speaking.
