Step Code Step Code
Step Code is StepFun's terminal-based coding agent that handles the full task loop — reading code, making changes, and running tests — powered by StepFun's Step-series models.
Step Plan launched around March 2026 with tiers starting at $6.99/mo (reported March 22, 2026); Step Plan moved to Credit-based monthly allowance billing; Step 3.7 Flash released ~May 2026 (198B/11B MoE, native multimodal); Step 3.5 Flash released ~Jan 2026; paid service agreement effective 16/03/2026.
As of
- Terminal-native agent that reads code, edits files, and runs tests in one loop
- Powered by Step 3.7 Flash (198B/11B sparse MoE, 256K context, native image/video) and Step 3.5 Flash
- Reliable tool calling and multi-step task decomposition/plan execution
- Works with mainstream agent harnesses and protocols (Claude Code, KiloCode, Hermes Agent, OpenClaw, MCP, Skills)
- Step Plan subscription with unified Credit billing across text, reasoning, speech, and image models
- OpenAI-compatible API endpoints with streaming and tool calling
Developers who want an affordable, terminal-first autonomous coding agent backed by StepFun's high-throughput reasoning models and a low-cost subscription.
Teams needing a fully free, no-subscription tool, or those who prefer GUI/IDE-centric workflows over terminal-based agents.
Step Code itself is an open-source terminal coding agent (free to use), but it runs on StepFun's Step Plan subscription: four tiers from $6.99/mo (400M Credits) to a $99/mo flagship, with Credits issued monthly (~$1 ≈ 7M Credits), non-rolling, plus booster packs. API token pricing also available (e.g., step-3.5-flash $0.10/$0.30 per 1M tokens).
Step Code offers a compelling terminal agent loop at a very low entry price, leveraging StepFun's underrated but capable Flash models and broad harness compatibility. However, it is tied to a paid Step Plan subscription with non-rolling monthly Credits, and its ecosystem visibility and tooling maturity lag more established competitors.
