Key Takeaways
Full Summary
OpenAI's engineering lead, Thibault Sottiaux, announced a 28-day challenge to enhance the Codex models, specifically GPT-6 Astra and GPT-6.1 Sol, which now generate around 50 tokens per second, up from 30. This improvement is part of a broader strategy to simplify and increase efficiency for users of Codex and ChatGPT Work.
The challenge includes daily updates, with the first being the speed enhancement, following a previous apology for slow performance. Developers are reacting with mixed feelings; some view the daily improvements as insufficient and are hoping for a reset of usage limits, while others are frustrated by the impending reduction in allowances for higher-tier plans.
The challenge's success will be judged by whether these incremental changes can compete with rival models like Anthropic's Claude Opus 5.5, which has gained significant traction among developers.
