❯ Anthropic says Claude now leads 26% of AI R&D work, up from 1% in six months

Task shareAnthropic told Bloomberg that Claude can now lead end to end about 26% of model R&D tasks from a high-level instruction, up from 1% in March, while people largely set goals, review outputs and handle exceptions.

Internal scaleThe company also said Claude performs substantial work in more than 90% of R&D activity, while roughly 30,000 agents operate at any moment on its most-used internal platform. It analyzed more than 1 billion agent decisions in August. These are Anthropic’s own workflow categories, not a claim that 26% of jobs or hours have disappeared.

Management controlsAs models move from code completion to decomposing tasks, running experiments and submitting results, research teams need stronger evaluation, permission and rollback systems. The useful comparison for rival labs is how many outputs enter production R&D under close human supervision, and how often they require rework or reversal.

▪ SIGNALClaude’s internal R&D value is shifting from how much code it writes to how many tasks it can close.
