@mattpsteele @OpenAI welcome to the team!

Codex for making a personalized daily digest:

[Ryan Doyle @doooyle]

surprised more people aren't doing something like this

Codex now creates a "newspaper" for me every morning

Unread messages, calendar, surf report, news

Anything I can do to stay off my phone until later in the day is a priority

[Greg Brockman @gdb]

you can just reset rate limits on things

[dominik kundel @aiDotEngineer @dkundel]

🖲️ We love our community! To celebrate getting together with many of you we brought @thsottiaux's reset button to AIE World's Fair.

Congrats Melanie for pushing the button 🎉

All Codex Go/Plus/Pro subscribers around the world are receiving a reset in the bank! Happy Codexing!

@beffjezos patience

[Greg Brockman @gdb]

Introducing GeneBench-Pro �� testing whether models can handle the kind of judgment-heavy analysis that real-world computational biology requires.

Problems would take a human expert around 20-40 hours to complete.

GPT-5.6 Sol is a big step forward.

[OpenAI @OpenAI]

We’re introducing GeneBench-Pro, a research-level benchmark for a harder kind of AI progress: how well agents can navigate messy biological data, choose the right analysis path, and make judgment calls that real computational research depends on.

Codex has gotten very good

[Corey Quinn @QuinnyPig]

Okay I owe my @OpenAI friends an apology for sleeping on Codex. I was not aware how strong your game was. This is... really quite something.

Personal finance now available for for ChatGPT Plus in the U.S.

[ChatGPT @ChatGPTapp]

Questions about dollars. Answers that just make sense.

Personal finance in ChatGPT is now available to Plus users in the U.S.

GPT-5.6 Sol preview — it's a good model:

[OpenAI @OpenAI]

Introducing a limited preview of GPT-5.6 Sol, our next generation frontier model, as well as GPT-5.6 Terra, a balanced model for efficient, everyday work, and GPT-5.6 Luna, a fast and affordable model for high-volume work.

digital ocean for running a codex remote session:

[OpenAI Developers @OpenAIDevs]

You can now spin up a persistent cloud development environment in one prompt with the @DigitalOcean plugin for Codex.

It runs in your DigitalOcean account and keeps working when you step away.

[Greg Brockman @gdb]

Agents are being adopted very quickly and accelerating work. How this looks across OpenAI itself:

[OpenAI @OpenAI]

Work at OpenAI is being transformed by agents, in every department.

Across our entire company, people are using Codex to do work that is more complex, longer-running, and increasingly cross-functional.

Our internal usage offers an early look at how agentic tools may reshape work as they become more capable and broadly available.

[Greg Brockman @gdb]

Big improvements to GPT-5.5 Instant, including being much more fun to talk to. Give it a try:

[OpenAI @OpenAI]

We have a new version of GPT-5.5 Instant for you, and it's much more fun to talk to.

Our most-used model is now better at understanding the intent behind a question and adapting its response accordingly.

It also handles complex constraints more reliably and makes shopping and local recommendations more useful and cohesive.

Rolling out today to paid users, tomorrow to free users.

[Greg Brockman @gdb]

Introducing Jalapeño — designed from scratch for LLM inference over nine months, accelerated by our models. Perf per watt looking incredible.

[OpenAI @OpenAI]

We’ve designed and built our first AI chip: Jalapeño.

Designed from the ground up by OpenAI and brought to production with @Broadcom, Jalapeño is purpose-built for the LLM workloads powering ChatGPT, Codex, the API, and future agentic products.

Chips are foundational to the AI economy. Building our own expands our full-stack platform from products to models to infrastructure, and will help us scale intelligence, serve more people, and expand access to AI.

Patch the Planet: using frontier AI and working with professional security researchers to secure critical OSS projects

[OpenAI @OpenAI]

Patch the Planet is our effort to help open source maintainers move from security findings to merged fixes.

We’re working with Trail of Bits, HackerOne, Calif, researchers, and maintainers to bring Codex Security and advanced models into the remediation process, with human review at the center.

[Greg Brockman @gdb]

Codex Security plugin for security teams: deep scans, validating findings, tracing attack paths, building threat models, generating codebase-specific patches for review, and exporting into other tools: https://t.co/jxlKnsQOAw

[Greg Brockman @gdb]

We're accelerating patching, in addition to vuln finding, with new tools and models in OpenAI Daybreak.

Our models are now discovering and generating patches for critical vulns in major browsers, network infrastructure, and operating systems (such as FreeBSD and the Linux kernel), and patching projects like cURL, Go, Python, Sigstore, and pyca/cryptography.

Working together with partners and the ecosystem to help secure the world's software:

[OpenAI @OpenAI]

We’re expanding OpenAI Daybreak to help democratize patching vulnerable software at machine speed:

- Codex Security plugin: find, validate, and fix vulnerabilities right inside Codex

- The full version of GPT-5.5-Cyber model: a great model for trusted defenders

- Cyber Partner Program: powering products built on top of our best cyber capabilities for leading security companies to secure the world's software

- Patch the Planet: working with maintainers to secure critical open source projects
