# In the News: September 18, 2026


Anthropic reports that Claude now leads 26 percent of its AI research and development work while roughly 30,000 agents perform research and engineering tasks at any one time. Its disclosure also describes the oversight system behind those numbers.

## 1. Claude leads 26 percent of Anthropic's AI R&D work

**[Measurements for understanding the pace of AI development inside frontier labs](https://www.anthropic.com/institute/measuring-pace-of-ai-development)** · Anthropic Institute · September 17, 2026

Anthropic built an internal index that rates every category of its AI research and development work on a six-level automation scale from Epoch AI, running from no AI involvement (AL0) to full autonomy with no human in the loop (AL5). As of August 2026, Claude "leads" 26 percent of that work, up from under 1 percent in February, meaning it can carry a task end to end from a high-level prompt while a human supervises the result. More than 90 percent of the work now sits at or above the level where Claude "collaborates," doing large chunks under close direction. Anthropic states the limit plainly: "Claude is not operating fully autonomously for any measured subset of AI R&D work."

The post also gives a detailed look at how Anthropic oversees roughly 30,000 agents doing research and engineering work at any one time. Each agent keeps a persistent identity that survives a model upgrade, so its activity record stays continuous. Agents post to a shared, open communication log where they can check each other's work and avoid duplicating it. Every action passes through a real-time monitor before execution and a second, after-the-fact monitor as well. Anthropic reports reviewing more than a billion agent decisions this way in August, of which about 1 in 47,000, or 0.002 percent, were blocked outright. The after-the-fact monitor flags roughly 100,000 transcripts a week for review, and on the order of 50 of the highest-priority flags reach a human each week.

**Why it matters:** Anthropic's numbers provide a production reference point for teams running many agents. Persistent identities preserve activity records across model upgrades, shared logs let agents check each other's work, and two monitoring layers review actions both before and after execution. Smaller teams can compare their own controls with a system operating at much greater scale.

The more transferable finding: models that passed the same evals still made different creative choices from the same brief, and a tool schema built on nested union types needed rewriting before the new model could use it reliably.
