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. https://t.co/je0041c6c2

I shared this note with @OpenAI today. Onward!

[Matt Knight @embeddedsec]

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!

When I started at OpenAI five years ago, AI agents that could secure software were nothing more than a fantasy.

Aardvark reminds us how far we’ve come since GPT-3, and this is still only the beginning.

Huge thanks to @sama and the @openai team for believing in the vision.

Congratulations to Team Atlanta for winning @DARPA and @ARPA_H’s AI Cyber Challenge. @OpenAI models were their top three! #aixcc

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!!)

(and a smaller one that runs on a phone).

super proud of the team; big triumph of technology.

[OpenAI @OpenAI]

What do you want to create next?

[Matt Knight @embeddedsec]

@MichaelKratsios Congratulations! Fantastic news.

@jaimeblascob @defcon @OpenAI It’s at 1050 tomorrow at the AIxCC Stage. Title is “Eating Our Own Dogfood” though I don’t believe the title made it onto the agenda.

[Matt Knight @embeddedsec]

I’m @defcon with the @OpenAI team. Interested in AI and security? Join me for the following:

- today at 1600: panel on the evolution of LLMs
- tomorrow at 1050: talk on how we’re using our LLMs for security at OpenAI

See you there!

[Matt Knight @embeddedsec]

I’ll also be recapping my and @marcnewlin’s escapades in the Spectrum Collaboration Challenge on a panel about @DARPA competitions at 1720 today.

[Matt Knight @embeddedsec]

Excited to give the closing keynote at the @BlackHatEvents AI Summit in one hour. Come learn about how we’re equipping the security team with LLMs @OpenAI.
