Claude 4 models are here 🎉 From research to engineering, safety to product - this launch showcases what's possible when the entire Anthropic team comes together. Honored to be part of this journey! Claude has been transforming my daily workflow, hope it does the same for you!
Introducing the next generation: Claude Opus 4 and Claude Sonnet 4.
Claude Opus 4 is our most powerful model yet, and the world’s best coding model.
Claude Sonnet 4 is a significant upgrade from its predecessor, delivering superior coding and reasoning.
Tour de force led by @_katieeverett investigating the interplay between neural network parameterization and optimizers; the thread/paper includes lot of gems (theory insight, extensive empirics, and cool new tricks)!
