Very excited for this model. It’s an enormous improvement over composer 2.5 and trained entirely from scratch. It’s been a pleasure working with the SpaceXAI team on it.
Even more excited by the slope of the effort and the models to come.

It’s our most powerful model yet and the first we've built for more than software engineering.
