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](http://openresponses.org/)

🆕 Codex now officially supports skills
Skills are reusable bundles of instructions, scripts, and resources that help Codex complete specific tasks\.
You can call a skill directly with $\.skill\-name, or let Codex choose the right one based on your prompt\.
Following the[agentskills\.io](http://agentskills.io/)standard, a skill is just a folder:[SKILL\.md](http://skill.md/)for instructions \+ metadata, with optional scripts, references, and assets\.
We’re looking forward to collaborating on the standard so it’s easy to share and use skill across different tools\.[](https://pbs.twimg.com/media/G8jULsYWUAAM6JA.jpg)
You can install scripts for just yourself in \(~/\.codex/skills\), or for everyone working on a project in \(repo\_path/\.codex/skills\)\.
We’ve also bundled a few handy system skills with Codex, such as plan, skill\-creator, and skill\-installer\.

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\.[](https://pbs.twimg.com/media/G5K8HGWWgAAKhQy.jpg)
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\.[](https://pbs.twimg.com/media/G5K8eEqWMAAevck.jpg)
