Our latest coding model, `grok-build-0.1`, is now available via the xAI API in public beta.

`grok-build-0.1` is a coding model specifically trained for agentic coding tasks, including web development, debugging, and MCP support. It's the same model that powers [Grok Build](https://docs.x.ai/build/overview#getting-started).

The model is served at a blazing-fast 100+ tokens/second and is priced at $1/m tokens in and $2/m tokens out. Outside of coding, it’s also a speedy, economical option for general-purpose agentic and tool calling use cases.

`grok-build-0.1` performs best in agentic harness like [Grok Build](https://docs.x.ai/build/overview), Cursor, [Hermes Agent](https://x.ai/news/grok-hermes), [OpenClaw](https://x.ai/news/grok-openclaw), [Kilo Code](https://x.ai/news/grok-kilocode), or [OpenCode](https://x.ai/news/grok-opencode). It’s also available via [OpenRouter](https://openrouter.ai/x-ai/grok-build-0.1) and [Vercel AI Gateway](https://vercel.com/changelog/grok-build-0-1-now-available-on-vercel-ai-gateway).
