Anthropic announced a new source control system for managing code generated by its Claude AI model.

What it means

Anthropic has built a custom source control system called Scion to manage the massive volume of code generated by its Claude AI model. Claude now writes over 80% of the code merged into Anthropic's codebase, and the volume of AI-generated code (over 30,000 daily merges) overwhelmed Git's capabilities. Scion is designed specifically for a world where AI generates code at scale, replacing Git for Anthropic's internal use.

Accuracy & sourcesGrounded

The claim is based on Anthropic's own engineering blog post and reporting by The Register, both reputable sources. The blog post is the primary source, and The Register's article is a secondary report that closely reflects it. Search results confirm the system name 'Scion', daily merge counts, and Claude's code share, making the claim solid.
