This is a AI post classified by Jev as Frontier models (a model release), kept by the AI Radar because it carries real work, not commentary.
Step 5 Preview from @StepFun_ai is 600B params total where only 27B are active, and their chart puts it at the level of GLM 5.3 and Kimi K3 at about 65% less cost per task. For us with a DGX Spark or more, it likely doesn't fit one 128GB pool even quantized, so it's a 2x> Spark build. Will update you on October 15th when it releases
