Alexandr Wang Says Muse Wonder Was Not Explicitly Trained on 3D Demo Games

Alexandr Wang thanked Meta Superintelligence Labs’ research teams after a week of launches, including Muse Wonder [full] and Muse Spark open. He said MSL and TBD began a little more than a year ago with the goal of producing a frontier model within a year or so, despite the ambition of that target given where Llama 4 landed. Wang said the teams have also built a scalable system for continuing to advance models at the frontier.

this was a big focus area for muse wonder; our goal was to build a model for everyone!

The whole team feels dumb now, but it's true: we did not explicitly train our model on 3D demo games. Obviously, in retrospect, we probably should've done a bit of that... but no regrets. Please try Muse Wonder on your actual coding work!
