# Anthropic

## Profile
The AI research lab behind the Claude family of models, including [[entity-claude-3-5-sonnet|Claude 3.5 Sonnet]].

## Relevance to the Source
Anthropic is presented as heavily 'dogfooding' its own technology:
- Claim: 90% of their codebase is now written by Claude itself. See [[claim-claude-writes-claude]].
- The Claude Code project lead, [[entity-boris-cheny|Boris Cherny]], has reportedly not written code personally in months.
- Leadership estimates the company is approaching 100% AI-generated code.

## Verification
Anthropic publicly discusses internal AI use, but **no validated public claim** of a 90% AI-written codebase exists. Treat the figure as directional.
