Commentary: OpenAI has stronger models internally and may be waiting to release
The author believes OpenAI was surprised by Opus 5.5, already has significantly stronger models internally, and may prioritize releasing GPT-6.1 Astra or even a "Bel" model, possibly at DevDay.
Honestly, that's what I thought too. I think OpenAI was quite surprised by Opus 5.5. It's no secret that OpenAI already has significantly stronger models internally. They've mentioned this repeatedly in their blog posts. And I suspect they're simply waiting to release it, especially after the recent security issues. In any case, I can easily imagine them prioritizing releases of GPT-6.1/5-Astra or even considering a "Bel" release. Presumably, DevDay will be very exciting!
