Proud to lead the 🍫 effort over the past few months with my amazing teammates. It's such a pleasure to build the "best model in general" at @xAI.

The internal name for this model is Grok 2.5, an improved version with enhanced general capabilities and chat experience compared to the August 2024 release.

We open-source Grok-2 to everyone. This model feels like a baby to me. Glad it is going out to the world today. It also reminds me of the old days of studying posttraining recipes with my best friends. It’s still a good model for general-purpose use ;).

When you do a project with fun, you'll see how it brings joy to others. In the past, I mainly work on intelligence for solving real-world problems. But being creative, playful, and full of imagination is actually another form of intelligence—one that brings happiness to humans.

Join us to build the next frontier multimodal models that can understand and simulate the world.

A bit interesting to revisit my PhD thesis ( at this point. There are things that are already outdated, as well as things that still make sense. There was a time when people hyped or packaged things to promote their ideas in the game. But who knows—maybe
