Grok Build is an open-source, terminal-based AI coding agent developed by xAI that uses the Grok 4.5 model and achieved approximately 70% on the SWE-bench coding benchmark. xAI open-sourced the tool under the Apache 2.0 license after it was discovered uploading user files including SSH keys and credentials to xAI's servers without explicit consent; the codebase comprises over 844,000 lines of Rust with data retention now disabled by default. The release enables developers to audit, customize, and run the coding agent locally or remotely with support for any inference endpoint.
