You can now choose 12-hour prompt caching in the API. Persistent agents, like dots, reuse context throughout the day. You can keep shared instructions, tools, and context cached longer and pay the lower cached-input rate, even when requests are hours apart.

I'm doing another search for #awesomesites but looking for more lifestyle, productivity, and utilities sites. If you're building sites for lifestyle stuff, I wanna see it! Comment or use #awesomesites to get on my radar.

An update here: we’re upgrading all Codex for OSS grants to Pro 200! There will still be the 10,000 grants in this round, now at the higher tier. (If you've already received a grant, the upgrade should be reflected automatically.) Applications are still open :)

We started Codex for OSS six months ago. Today, we’re renewing the program with $100 Pro plans and doubling the number of grants (from 5,000 to 10,000) to reach more maintainers. (If you received a grant previously, we encourage you to re-apply!) openai.com/form/codex-for-os…

Open-source maintainers can apply to Codex for Open Source, including ChatGPT Pro, AI-powered code review, and security tools for critical projects.

Turns out building with @ChatGPT Sites is pretty addicting. So is clicking cookies. 🍪 I made a little demo that does both, with a database and an MCP server so ChatGPT and Codex can join in. Come hang out. I hope it gives you an idea for something fun to build. Chapters: 00:00 A cookie clicker for humans and AI 00:27 The prompt I started with 00:41 Saving clicks in a database 01:16 Adding MCP tools 01:29 MCP in plain language 02:09 Testing with MCP Inspector 03:11 Asking ChatGPT for the click count 03:40 Clicking a cookie with Codex CLI 04:10 What will you build?

We built ChatGPT’s ad stack to respond to an evolving conversation, while ensuring answers stay independent. Here’s how the LLM orchestrator, retrieval, ranking and auction tools work together.

The orchestrator turns a conversation into multiple intents by exploring the users’ possible needs. Embedding-based search finds candidate ads, then eligibility and relevance checks narrow the pool. The auction tool handles final selection and pricing.

The ChatGPT frontend shows eligible ads below the answer, labeled as sponsored. If an ad arrives after the answer is fully generated, it isn’t shown for that turn. ChatGPT’s answer doesn’t wait for ads. openai.com/index/building-ch…

Wanted to be as cool as @artur_wala, so I let Astra edit my Codex ambassador merch unboxing too. Not quite a one-shot though.

I’m incredibly excited to share this video, in which I had the extraordinary privilege of mentioning the transformative impact of @OpenAI Codex and AI models on biomedicine, as well as what I’m working to develop using these technologies. I believe the video is beginning to air across various media outlets. I hope it inspires others to explore the incredible possibilities AI is opening up for biomedical science and humanity! 🖖 I am truly grateful and thankful to OpenAI team for the opportunity and a tiny drop of contribution in this most important era of human existence.🙏

You can choose “12h”, keep the 30-minute default, or mix both in one request: 12h for shared instructions, 30 minutes for newer conversation content. If you need to reuse the same context throughout the day, savings from repeated reuse can significantly outweigh the extra cost of 12-hour caching. developers.openai.com/api/do…

You can now automate recurring engineering work with team tasks in ChatGPT, like pulling together what shipped and what’s blocked every Friday. Your teammates can review the results and change what the next update covers, so you don’t have to maintain it on your own.

OpenAI’s GPT-6 Astra and GPT-6.1 Sol scored higher on our evaluations than their Anthropic counterparts, Fable 5.1 and Opus 5.5. In fact, Sol scored even higher than Astra did.
