GPT-6.1 Sol is our most demanded model pretty much ever both across both the API and subscriptions.
Within ChatGPT & Codex, we were under heavy load, but have brough more capacity online and the speed should get much better in the coming hours, reaching almost twice the speed compared to what we served yesterday.
If you build on GPT-6.1 Sol in Codex or the API, expect load-related slowness to ease as more capacity comes online, with speed near double the prior day.
