Codex is getting easier to automate and customize around your code.
🪝 Hooks customize the Codex loop with scripts that run at key points in a task:
• Run validators before or after work
• Scan prompts for secrets
• Log conversations to internal systems
• Create memories or customize behavior by repo or directory
⚙️ Programmatic access tokens provide scoped credentials for Business and Enterprise teams:
• Create tokens from ChatGPT workspace settings
• Use them in CI, release workflows, and internal automations
• Set expirations or revoke access when needed
• Keep usage tied back to the workspace
• • •

We’re having way too much fun working through your feedback.
(Please, keep it coming.)
Keyboard shortcuts are now customizable.
Set Codex up around how you actually work, then tweak shortcuts from settings instead of adapting to our defaults.
Git actions are easier to reach.
We moved key git controls back into the review flow, so common actions like commit, push, branch, PR creation, and PR status are closer to where you’re already working.
Improved thread panel.
Related context and controls now load and behave more cleanly from the thread header: summaries, local state, Git context, sources, and more.
Today we’re announcing Open Responses: an open-source spec for building multi-provider, interoperable LLM interfaces built on top of the original OpenAI Responses API.
✅ Multi-provider by default
✅ Useful for real-world workflows
✅ Extensible without fragmentation
Build agentic systems without rewriting your stack for every model: openresponses.org
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.
