发现一个很离谱的模型，400 TPS 的输出速度，比 DeepSeek-V4 Flash 快 2 倍多还有超强的多模态理解 + 搜索检索 + 推理综合，这居然是一个 Flash 模型能同时做到的我让它帮我写了一个竞品分析 Agent：输入一张产品官网截图，自动完成"读图提取 → 搜索市场数据 → 输出竞争分析"的全流程。然后用

最近拿 StepFun 的 Step 3.7 Flash 跑了一次完整的自动编程流水线，从需求文档到能用的工具，65 分钟，中间没碰键盘。先说模型。Step 3.7 Flash 的定位是把 Agent 工作流从头跑到尾：规划、写代码、跑测试、审代码、出错重试，看的是整条流程跑完的综合效率。原生多模态，开源可部署。Agent

Great to see Step 3.7 Flash live on @FireworksAI_HQ. Designed for inference from day one, Step 3.7 Flash combines a hardware-friendly architecture with MTP-assisted decoding to reach up to 400 tokens/s. Fast, multimodal, and ready to power capable agents in real-world

Many research labs only consider inference efficiency after the fact. Step 3.7 Flash is a 198B sparse MoE VLM designed by @StepFun_ai for inference from the start. 196B language backbone with a 1.8B vision encoder. Built for real-world agent workloads, running at up to 400

Thanks @ArtificialAnlys for the detailed independent evaluation. Step 3.7 Flash is built with a clear focus on the intelligence-speed frontier: MTP-assisted decoding, 400+ output tokens/s, stronger agentic performance, native multimodal capabilities, and Apache 2.0 open weights.

StepFun's Step 3.7 Flash sits on the Intelligence vs Output Speed Pareto frontier, scoring 43 on the Artificial Analysis Intelligence Index and is served at over 400 output tokens/s Step 3.7 Flash (open weights, Apache 2.0) is a significant upgrade on Step 3.5 Flash and stands

Great demo by @atomic_chat_hq. Step 3.7 Flash was designed for real-world agentic coding tasks — not just generating code fast, but keeping logic, visuals, and execution coherent across complex outputs. Love seeing builders test it in creative ways!

StepFun Step 3.7 Flash smashed DeepSeek V4-Flash in a physics contest We gave two open-weight models the same task: write a self-contained HTML5 canvas animation with real physics in one file without libraries. Three scenes - a Galton board, balls bouncing in a spinning hexagon

Open weights are moving from model cards into real coding workflows. Step 3.7 Flash is designed for fast agentic coding, reliable tool calling, and multimodal understanding. Big thanks for the blog from the @kilocode team:

The open-weight labs did not come to play this week. StepFun dropped Step 3.7 Flash. MiniMax dropped M3. Both with open weights, both already live in Kilo. The "model wars" just got a lot more interesting.

Step 3.7 Flash is now FREE in @kilocode 🎉 It was built for how coding agents actually work. That means multi-step orchestration and reliable tool use across a real codebase, not just fast replies. Try it on a real task in your editor, like a multi-file change or an actual bug!

Intelligence got us here. Efficiency is what gets real work done. At ClawCon Macao, our GM of Developer Business @EileenTal laid out the next frontier for agents — and the thinking behind Step 3.7 Flash. 👏
