Anthropic reinvents source control as Claude floods the world with code
Anthropic's Claude models have been emitting so much code that the company's coding infrastructure hasn't been able to keep up.
It's a symptom of the AI coding imperative and all-you-can-eat inference.
Microsoft's GitHub in April published a blog post attributing recent availability problems to the exponential growth in pull requests and commits.
The code flood has been noted by academic researchers, among others.
For Anthropic, writing code is no longer a productivity bottleneck.
Instead, the problem is managing the code after it's written, via source control, the build system, and continuous integration.
"In May 2026, Anthropic averaged around 2,500 code changes merged per day; as of September, we merged over 30,000 per day," the biz said in a blog post on Tuesday.
"We don’t expect this rate of growth to slow down anytime soon; the latent demand for merging code is practically infinite, and every bottleneck we remove immediately leads to a further increase in the amount of code we produce." After several months of model prompting and five months of migration, the result is a homemade version control system called Scion, a monorepo scheme that sounds a bit like Subversion, Apache's centralized version control system.
Anthropic is not the first organization to look beyond Git's distributed architecture toward centralized source control.
Google uses Piper, a monorepo system (along with Gerrit for Git-based code reviews).
Microsoft has Virtual File System for Git, formerly GVFS, to help overcome some of the scaling issues with Git.
Meta has Sapling.
But as the AI biz notes, Claude's code writing ability both created the situation and offered a way out through the creation of scalable code infrastructure tools – in addition to Scion, Claude helped conjure Antique (a code review interface), a code search tool, and a source control IAM system.
The decentralized approach embodied by Git is the right one for most code repos, according to Anthropic.
