Proud to introduce Aardvark, our agentic security researcher powered by GPT-5.
Aardvark hunts for vulnerabilities the way a security engineer would: by reading and analyzing code, writing and running tests, and proposing patches.
Now in private beta. openai.com/index/introducing…

Great conversation with Joel de la Garza on the @a16z podcast. We covered agentic security research with Aardvark, where AI and security are headed, and reflections on five-plus years @OpenAI. Thanks for having me!

gpt-oss is out!
we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!)

super proud of the team; big triumph of technology.
