OpenAI has not officially announced GPT-5.6, but a brief reference in their internal Codex backend logs, later removed, suggests the model's existence. This log entry, along with a crowd bet on Polymarket placing the release odds at 80-89% by June 30, 2026, are the only verifiable pieces of information. While rumors of codenames like 'iris-alpha' and a potential 1.5 million token context window exist, these remain unconfirmed and are likely speculative. AI
