OpenAI raises default GPT-6 Astra and GPT-6.1 Sol inference speed by about 50% across Codex, Work and Sign in with ChatGPT integrations

What changed

QbitAI reported on October 6, citing Codex lead Thibault Sottiaux's same-day public update, that OpenAI increased the default inference speed of GPT-6 Astra and GPT-6.1 Sol by roughly 50%, to about 50 tokens per second. The improvement applies to Codex/Work subscriptions as well as third-party products connected through Sign in with ChatGPT. This is a server-side inference and capacity improvement rather than a new model release or a new Ultrafast tier; the report also notes that GPT-6.1 Sol had suffered noticeable slowdown during its initial load spike.
