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.
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.
GPT-5.6 Sol is our most capable model yet for cybersecurity.
It shifts the performance-efficiency frontier for long-horizon security tasks including vulnerability research and exploitation.
GPT‑5.6 Sol launches with our most robust safety stack yet.
We strengthened real-time protections against high-risk cyber activity and repeated misuse, then spent weeks hardening the system with human red teaming and over 700,000 A100-equivalent GPU hours of automated testing.
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
I’m very excited about this article from @OpenAI on my attempt to use GPT-5 Pro to understand the results of an experiment we did several years ago. Remarkably, GPT-5 Pro figured out the key mechanisms, as explained in the article & infographic below!
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
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
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
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
We’re also launching the OpenAI Daybreak Cyber Partner Program with leading security software and services providers.
Participating partners can use GPT‑5.5 with Trusted Access for Cyber in the security products and services they provide to customers.
This allows their
