Grok Build 0.1 now available via xAI API

Dear API customers,

Our new coding model, grok-build-0.1, is now available via the xAI API. Customers, including Notion and KiloCode, have loved its high speed, app building capabilities, and cost effectiveness.

Try it now ↗

grok-build-0.1 was specifically trained for agentic coding tasks, including web development, debugging, and MCP support. It's the same model that powers the Grok Build CLI.

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.

To get started, create an API key here.

grok-build-0.1 is also available via OpenRouter and Vercel AI Gateway.

Sincerely,
The xAI Team
