GROK 4.5 IS NOW ON THE FRONTIERCODE LEADERBOARD
Cognition just launched the FrontierCode leaderboard — a new benchmark specifically designed to track which AI models are writing code you’d actually merge into production.
Unlike many synthetic benchmarks, FrontierCode focuses on real-world usability, with full methodology and sample tasks publicly available.
Grok 4.5 is included in the rankings alongside other top models.
This is another step toward measuring what actually matters for developers: code that works, integrates cleanly, and solves real problems.

instead of watching 2 hours of Netflix tonight, watch this Stanford lecture

it's the clearest explanation I've seen of how LLMs like ChatGPT and Claude actually work

useful whether you've never touched AI in your life or have been using it every day for the past year

I took the key ideas and turned them into a practical guide on how to actually build LLM from scratch

find it below

Technology never ceases to amaze me. It's incredible how it connects us, simplifies our lives, and sparks creativity in ways we never imagined. Can’t wait to see what’s next!
