Elon Musk open-sourced Grok Build
The terminal agent stack is now open source: file reading, context gathering, command execution, plugins, and subagents. The Grok 4.5 weights are not included, the model itself is still closed.
Now anyone can see how Grok works with code, fork the agent, and plug in a local model. xAI basically handed the community a build-your-own Claude Code kit.
