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!

Context

Per StepFun's post, Step 3.7 Flash is now free inside Kilo, an open-source coding , with StepFun framing the model's value around multi-step orchestration and reliable across a real codebase, rather than fast single-turn replies, and suggesting it be tried on a real multi-file change or bug.

StepFun's own launch specifications for Step 3.7 Flash report a score above 98 percent on tau-squared-bench across all difficulty levels, a that specifically measures whether an agent's tool calls stay reliable and consistent over a multi-step task rather than drifting or breaking (launch specifications), which is the property Kilo's framing is pointing at.

AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
tool use — A model's ability to call external functions — run code, search the web, edit files — instead of only generating text.
benchmark — A standard public test set for comparing AI models — the shared scoreboards behind every "model X beats model Y" claim.
