🚀 UCSB CS fam — we did that. 💻🔥

After two years deep in DARPA’s elite AIxCC competition, UCSB SecLab just got official recognition from OpenAI for a legit “proof of hacking” moment:
👉 10 BILLION tokens used. 🤯

Those tokens poweredthe creation of Artiphishell, which achieved the ranking of Top 5 Cyber Reasoning Systems in the WORLD 🌍🏆

For scale: that’s like running ~2,740 solid ChatGPT conversations every single day for two years. Yeah… that’s a lot of chatting! 😅

If you’re into AI, security, systems, or pushing CS to the edge, this is what UCSB looks like when it cooks. 👨‍💻👩‍💻🔥

🌟 UCSB Crushed It! 🌟

We sent 5 amazing teams, and every single one delivered impressive results — placing 4th, 10th, 15th, 23rd, and 26th out of nearly 70 teams! They tackled problem sets like champs, solving 11, 10, 9, 6, and 5 problems, respectively. 💪🧠

🔥 Special shoutout to Team UCSB WA —
Ezra Furtado-Tiwari, Om Mahesh, and David Qiao — who placed 4th, solved the same number of problems as the winning team, and officially qualified for the National Contest! 🎉

They’re headed to the 2026 National Finals at the University of Central Florida College of Engineering & Computer Science in Orlando from March 19–22, 2026, where teams will compete for the chance to go to the World Finals. 🌍✨

Let’s give them a BIG congratulations and cheer them on as they prepare for the next stage! 💙🐚💻
