From negligible to a quarter of activity

The figures trace a steep climb over roughly half a year. In February, AI-led development accounted for under 1 percent of the relevant activity — a marginal presence. By August, that share had leapt to 26 percent, meaning AI systems were by then directing about one in four of the AI development efforts captured by the measure. Few indicators in the technology sector move with that velocity, and the numbers quickly spread across social media and industry discussion as evidence of how rapidly AI has begun to shape its own advancement.

What the verification found

To test the claim, reviewers examined seven primary sources tied to the statistic rather than relying on secondhand summaries. The source material backed the core trajectory: a February baseline below 1 percent and an August reading of 26 percent. The rating fell short of full endorsement, indicating that while the headline figures hold up against the underlying documentation, some element of the claim's framing or context warranted qualification rather than a clean pass.

The finding matters for how the industry reads automation in research itself. A 26-percent share, up from almost nothing within a single year, suggests AI systems are no longer merely tools in AI development but increasingly the driving hand within it. On the basis of the seven primary sources reviewed, the claim that AI-led AI development rose from under 1 percent in February to 26 percent in August is Mostly True.
