haider1 · x · 2026-07-23
Rumors suggest Codex is preparing a few launches today:
- GPT-5.6 Sol “spark” may run on Cerebras hardware at up to 750 tok/s, said to be roughly 5× faster than typical frontier models.
- A real-time voice mode for Codex is also mentioned, able to orchestrate background coding and broader tasks.
This is framed as an imminent ship list rather than a confirmed announcement.
