Step 3.7 Flash 解决了智能体场景中速度与可靠性的平衡问题，做智能体开发、编码自动化和多模态应用的团队可以直接用开源权重部署，值得一试。
StepFun 发布了 Step 3.7 Flash 模型，这是一款面向智能体、编码、搜索和多模态工作流的高效模型。该模型采用 198B 稀疏 MoE 架构，仅激活约 11B 参数，支持 256K 上下文和三种推理级别，推理速度达 400 TPS。在 ClawEval-1.1、SimpleVQA Search 和 SWE-PRO 等基准测试中表现领先，并支持视觉理解、工具调用和本地运行。模型权重以 Apache 2.0 开源，可在 Mac Studio、DGX Spark 等设备上运行。

Read more in @StepFun_ai ’s launch post: StepFun @StepFun_ai ⚡️ Step 3.7 Flash is here: The new frontier is agent efficiency. #1 ClawEval-1.1 (67.1), #1 SimpleVQA Search (79.2), #2 SWE-PRO (56.3), 95.3 on V* Python. Open weights under Apache 2.0. Built for agentic, coding, search, and multimodal workflows — balancing speed, cost, and reliable execution. - 400 TPS. 198B sparse MoE, ~11B active. 256K context, 3 reasoning levels. - Understands UIs, charts, docs, images — then writes code or calls tools to act on what it sees. - Web + visual search reaches further: more sources, deeper follow-up. - Reliable tool use — less drift, fewer broken toolcalls. 98%+ on τ²-bench across all difficulty levels. - Works with Claude Code, KiloCode, Hermes Agent, OpenClaw, and protocols like MCP. - Runs locally on Mac Studio M4 Max, DGX Spark, AMD AI Max+ 395.
