only beautiful Tiny Ui happening in the Codex app

Agent workflows got even faster. You can spin up containers for skills, shell and code interpreter about 10x faster. We added a container pool to the Responses API, so requests can reuse warm infrastructure instead of creating a full container creation each session. #hosted-shell-quickstart" target="_blank" rel="nofollow noopener">developers.openai.com/api/docs/guide…

@zapier @OpenAI 🤝

GPT-5.4 Mini & Nano are live in Zapier. We ran the benchmarks 🧵 Both of @OpenAI's new models matched Haiku 4.5's performance at roughly half the cost. Mini on low reasoning, Nano on medium reasoning. OpenAI built these models specifically for high-volume, latency-sensitive work: coding assistants, subagents, image processing. Fast by design, not by compromise. Building at scale? Need speed without blowing your budget? Try them in Zapier now.
