Per Anthropic's Michael Sellitto at an IMF panel on AI and cyber risks, Anthropic projected for the first time that Claude will drive 80-90% of its frontier model training by 2027, up from 1% in March.

Internal coding stats he cited: about 0% of Anthropic's code was written by Claude at the start of last year; 50% by August after a new model release (engineers said it finally coded at their level); 80-90% by year-end.
