@__aplace__ @POSTECH_PLUS @postech1986, drop some tokens to *WIN* the science war!!

[beta @betarixm]

@__aplace__ Yeah, at $18 a challenge, @POSTECH_PLUS would go broke.

My new job: organic, slow, cost-effective (at least for now) token generator.

Though it was a first deploy of catchy, it showed insane perfomance.

Another lesson: still tokens are expensive for CTF, so local LLM seems very promising for long-term research. PLUS need machine.

We just debuted Xint Code, our new code analysis tool building on work from on our AIxCC submission in August.

With zero human intervention, it found critical 0day RCE bugs in Redis, PostgreSQL, and MariaDB – sweeping the database category and beating out every human team.
