o4

OpenAI

Not out yet. OpenAI hasn't released o4, and no release date is confirmed. What we know so far: no date; OpenAI never shipped a full o4; o4-mini's API shuts down Oct 23 (its replacement: GPT-5.6 Terra). Swept every 60 seconds across provider catalogs. The moment it answers on a public API, alerts fire: a text or a call on paid plans the second it's confirmed, then a free Chrome push and email about 15 minutes later.
