Grok Build 0.1, our fastest coding model, is now available via the xAI API in public beta.
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 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.
