Step 5 Preview Launch Night 🚀 @SF
We just launched Step 5 Preview, and we'd love for you to be among the first to see it up close.
Step 5 Preview is StepFun's new open-weights flagship LLM for real-world agentic work: coding, professional knowledge work, and finance. Frontier-level results, at a cost that makes running agents all day actually affordable. Available now, open weights on October 15.
