OpenAI has finally put a date on GPT-5.6, although the wording still matters. The Developer Community announcement says the Sol, Terra, and Luna series is "Coming July 9", while the Help Center still frames it as a limited preview for trusted API and Codex partners, not a ChatGPT switch flipped for everyone, which is the interesting part. The model is now official enough to price, document, and system-card, but still gated enough to feel half-released. Tomorrow may be the public date, or just the next aperture. Either way, the rumour phase is over, and the launch has become a schedule.
