Remastered the ESGenius Pipeline using nano banana pro 🍌 — cleaner, more stylish, and now fully comprehensive. A revolution in academic diagramming lol. 🤩🤩🤩 Paper: aclanthology.org/2025.emnlp-mai… #EMNLP2025 #LLMs #Benchmark #ESG #Sustainability

I'm a manager at @OpenAI, but with GPT-5.5 I'm a more effective IC than I've ever been. I can now write CUDA kernels like a pro. I can rely on it to run my research experiments. And we know how to make it much more powerful from here.

I had a good time discussing yesterday's Google TPU v8t and v8i announcement at Cloud Next with Amin Vahdat along with @AcquiredFM hosts @gilbert and @djrosent. The blog post announcement has lots of details about these new chips: blog.google/innovation-and… Here's a thread of some particular things I'm excited about:

codex made its own launch video

🚀 Codex CLI 0.124.0 is out! 🪝 Stable hooks with inline config.toml support ☁️ Amazon Bedrock support with AWS SigV4 auth 🎛 Alt+,/Alt+. quick reasoning controls in TUI Changelog: github.com/openai/codex/r…

Have you read "The Prompt: Insights from OpenAI Global Affairs"? This week in their "AI Politics are Local" edition, they shared: - How 2026 candidates are talking about AI - Our blueprint for patient-first AI in healthcare Read it now: openaiglobalaffairs.substack.com/p/ai-politics-…

We tried a new thing with NVIDIA to roll out Codex across a whole company and it was awesome to see it work. Let us know if you'd like to do it at your company!

New in the Codex app: - GPT-5.5 - Browser control - Sheets & Slides - Docs & PDFs - OS-wide dictation - Auto-review mode Enjoy!

fun bonus: we shipped a .tex plugin

One day while testing GPT-5.5, I had my first taste of AGI. We had a branch with hundreds of visual and front-end changes, plus complex refactors. At the same time, main had changed a lot too. Conflicts everywhere.

important (and very jakub-coded) jakub quote:

Codex + 5.5 is incredible for the full spectrum of computer use. No longer just for coders, but for anyone who does computer work (including creating spreadsheets, slides, etc).

GPT-5.5 is now available on ChatGPT and Codex.

With GPT-5.5, Codex now gets more of the job done across the browser, files, docs, and your computer. We've expanded browser use so Codex can interact with web apps, and test flows, click through pages, capture screenshots, and iterate on what it sees until it completes the task.

GPT-5.5 Pricing & GPT-5.5 Pro Pricing GPT-5.5: $5/$30 GPT-5.5-Pro: $30/$180 (Input/Output per million tokens)

Introducing GPT-5.5... together with a ton of new Codex features (more on those in the next hour). Included in all paid plans and coming to API soon. Update your Codex app or CLI to use it. openai.com/index/introduc…

这个开源导弹追踪器简直太疯狂了！！

API pricing will be $5 per 1 million input tokens and $30 per 1 million output tokens, with a 1 million context window. (Remember, you will need less tokens per task than 5.4!)

GPT-5.5 is our strongest agentic coding model to date. It reaches 82.7% on Terminal-Bench 2.0,with stronger performance on command-line workflows and GitHub issue resolution. In Codex, GPT-5.5 can carry coding tasks further end to end, from understanding the codebase to making changes, debugging, testing, and validation.

GPT-5.5 is here. It’s our smartest frontier model yet, introducing a new class of intelligence for agentic coding, computer use, knowledge work, and scientific research. Rolling out in ChatGPT and Codex today. API is coming soon.

1. We believe in iterative deployment; although GPT-5.5 is already a smart model, we expect rapid improvements. Iterative deployment is a big part of our safety strategy; we believe the world will be best equipped to win at the team sport of AI resilience this way. 2. We believe in democratization. We want people to be able to use lots of AI; we aim to have the most efficient models, the most efficient inference stack, and the most compute. We want our users to have access to the best technology and for everyone to have equal opportunity. We have been tracking cybersecurity as a preparedness category for a long time, and have built mitigations we believe in that enable us to make capable models broadly available. 3. We love you and we want you to win. We want to be a platform for every company, scientist, entrepreneur, and person. (My whole career has largely been about the magic of startups, and I think we are about to see that magic at hyperscale.)
