- Step-3 is Large yet Affordable: Model-system Co-design for Cost-effective Decoding (2025 · 26 citations)
Decoding is the costliest stage of LLM serving per generated token, because hardware utilization is low. This matters most for reasoning models that produce long outputs. StepFun argues that parameter counts predict this cost poorly. Their paper presents Step-3, a 321B-parameter VLM that activates 38B parameters per… - Step-Video-T2V Technical Report: The Practice, Challenges, and Future of Video Foundation Model (2025 · 21 citations)
