Nedeľa 26. júla 2026 • Source: xAI

What's new

Grok Build open source: source code published at github.com/xai-org/grok-build — ~1M lines of Rust (~51M+ bytes)
Fully local operation: compile yourself, point at your own local inference, configure via config.toml
Included components: agent loop, code read/edit tools, terminal UI, skills, plugins, hooks, MCP extension system
Plan mode: agent presents a plan for user review before execution
Terminal Grok queries: ask Grok questions directly from the terminal while working

Why it's worth attention

Open-sourcing a full coding agent lets the community audit, extend, and deploy it with their own models — including local ones. This move comes amid growing interest in the open-weight ecosystem.

How to try it

Clone the repository at github.com/xai-org/grok-build and compile using the Rust toolchain. See README for details.
