Step 5 Preview Launch Night 🚀 @SF

We just launched Step 5 Preview, our new open-weights flagship LLM, and we'd love for you to be among the first to explore it up close.

Co-hosted by StepFun and Together AI, this launch night brings together founders, developers, and AI builders for a model introduction and live Q&A, a panel on what’s worth building as AI models improve, and conversations over food and drinks.
