Great to see Step 3.7 Flash now available through @baseten. We built this model for real-world agent workflows, with native multimodal understanding, reliable tool use and the efficiency needed for production. Thanks to the Baseten team for the great collaboration.

Step 3.7 Flash is now in the Baseten Model Library! This is a 198B-parameter sparse MoE model (11B active per token) with native image and video input, and a 256K context window. It's a strong option for visual reasoning, agentic coding, and long-context tasks.

Step 3.7 Flash is currently top 10 on @OpenRouter this month, with 4.29T tokens routed. Builders are pushing it through real agent runs, coding tasks, and long-context workflows. Keep sending the hard stuff.

Been great seeing Step 3.7 Flash get real use in Nous Portal: people testing, building, and running all kinds of agent workflows with it. We’re keeping free access going with the @NousResearch! Try it out and send us what you make.

Step 3.7 Flash hits #2 on Claw-Eval General for autonomous agents. We’re seeing strong performance across multi-step execution and robustness in long-horizon tasks, ranking just behind Claude Opus 4.6. Promising signals for real-world agent workloads.

This is the kind of agent workflow Step Plan was built for: connect it once, push through a real build, and keep experimenting without thinking about every single API call. Love the tarot generator demo. Thanks for testing Step 3.7 Flash in Claude Code, @codedailyML 🙌

I used to dread heavy testing days because every API call felt like watching money disappear in real time. Found a backend built to run flat instead of per call, made specifically for agent work. Pointed my Claude Code setup at it and had it running in under 5 minutes. Here's

This is the pain we kept hearing from builders: once an agent starts doing real work, the meter becomes part of the workflow. Step Plan is our attempt to make that less of a distraction. Thanks for putting Step Plan + Step 3.7 Flash through a real Claude Code setup 🙌

I almost stopped testing new models altogether. Not because they were bad. Because every call left a number climbing in the corner of my screen, and at some point I started watching that number more than I was building. A flat-rate backend fixed that for agent work. I swapped

Excited to partner with @cline to bring Step 3.7 Flash to more coding agent builders. Step 3.7 Flash is now free in Cline for the next month — capable, fast, and reliable for agentic coding workflows. Try it in Cline: /model → Step 3.7 Flash Big thanks to the Cline team.

Step 3.7 Flash is free in Cline for the next month. It beats Gemini and DeepSeek flash models, and comes surprisingly close to frontier performance on SWE Bench. Open weights, 256k context window, fast and reliable. npm i -g cline Run cline > use /model > select Step 3.7 Flash
