You can now get more Codex usage from your plan and credits with three updates today: 1️⃣ GPT-5-Codex-Mini — a more compact and cost-efficient version of GPT-5-Codex 2️⃣ 50% higher rate limits for ChatGPT Plus, Business, and Edu 3️⃣ Priority processing for ChatGPT Pro and Enterprise

GPT-5-Codex-Mini allows roughly 4x more usage than GPT-5-Codex, at a slight capability tradeoff due to the more compact model. Available in the CLI and IDE extension when you sign in with ChatGPT, with API support coming soon.

Select GPT-5-Codex-Mini for easier tasks or to extend usage when you’re close to hitting rate limits. Codex will also suggest switching to it when you reach 90% of your limits, so you can work longer without interruptions.

We’ve also landed efficiency improvements to get more out of our GPUs. ChatGPT Plus, Business and Edu users get 50% higher rate limits as a result, and Pro and Enterprise accounts get priority processing for maximum speed.
