It really looks like OpenAI is launching a major, significant release next week, one that was originally intended for DevDay. My money is still on GPT-6.1 Astra, or perhaps an even newer checkpoint released in response to Opus 5.5 / Fable 5.5. Caveat: There was a lot of hype leading up to DevDay as well, so I remain cautiously optimistic.
