Grok Build 0.1 as a coding agent in your terminal

Strengths

xAI's coding-focused Grok model.

OpenRouter's description:

Grok Build 0.1 is SpaceXAI’s fast coding model trained specifically for agentic software engineering workflows. It supports text and image inputs with text output, and is optimized for interactive coding...

Use Grok Build 0.1 as a coding agent in your terminal

Start Darce in your project with Grok Build 0.1:

npm install -g darce-cli
darce --model x-ai/grok-build-0.1

Already in a session? Type /model x-ai/grok-build-0.1, or open the picker with Ctrl+P. Darce then reads your code, edits files and runs commands with Grok Build 0.1; risky commands ask first, and /undo reverses any change, including what shell commands did. No account yet? npx darce-cli lets you try it free. Which plan includes which models is on the pricing page.

Make it your default or a gear

In ~/.darcerc, set it as the starting model or add it to the gears you move between with Shift+↑ / Shift+↓ (see configuration):

{
  "router": { "default": "x-ai/grok-build-0.1" },
  "gears": ["qwen/qwen3-coder", "x-ai/grok-build-0.1"]
}

Compare it on your own code

Benchmarks rarely match your repository. Race Grok Build 0.1 against two other models on a real task and keep the best diff:

/derby --models x-ai/grok-build-0.1,x-ai/grok-4.7,openai/gpt-5.3-codex fix the failing test
