Inside Anthropic 26% of its AI R&D work has reached the point where Claude can do most of the task end-to-end from a high-level instruction.

A human mainly supervises.

• “As of Aug 2026, there were approximately 30,000 agents doing research and engineering work at Anthropic at any one time in our most-used internal platform.”

• More than 90% of measured Anthropic R&D already has AI doing substantial chunks of the work or more

“The share of work at or above “AI collaborates” is above 90%.”

• More than a billion agent decisions in one month is the scale here; the online monitor blocked roughly one in every 47,000.

“We analyzed over a billion decisions from our research & engineering agents over August 2026 and found that 0.002% of them (about 1 in 47,000) were blocked by this monitor.”
