Anthropic says more than 80% of merged code in its systems was written by Claude by May 2026, raising its concern that AI-assisted engineering could accelerate recursive self-improvement.
What changed
The article frames the move as a structural shift: model capability, distribution and data control are now being negotiated separately.
What to watch
The next question is whether the deal changes customer behavior or mainly resets bargaining power among platforms, model labs and regulators.
