Nearly 2,000 agents read a whole-brain atlas in 32 minutes
PerturbAI says a collaboration with OpenAI and Scripps Research ran thousands of reasoning agents on an existing whole-brain atlas and finished in 32 minutes.

On October 21, 2026, PerturbAI said agents developed with OpenAI interpreted its whole-brain genomic atlas in 32 minutes. The announcement is an orchestration result: many agents on one existing dataset, compared with reports from a single agent.
The San Francisco company described results from a year-long collaboration with OpenAI. Working with Scripps Research, the teams built a framework for interpreting large experimental datasets, connecting results to published research, and generating hypotheses for scientists to test. PerturbAI says those findings are in a joint preprint and a blog post.
Thousands of agents analyzed cellular responses, searched the scientific literature, and linked experimental results to existing biological knowledge. The system then produced a reasoning atlas tying together genes, cell responses, prior studies, and possible biological mechanisms. Applied to PerturbAI's whole-brain atlas, analysis and synthesis of evidence-linked findings finished in 32 minutes. The release compares that with an estimated months to a year of serial human analysis and literature review.
The tighter count is in this release. Joy Jiao, head of life sciences at OpenAI, is quoted saying the run used nearly 2,000 agents in parallel. PerturbAI's own summary says thousands of agents, not that exact count.
Human biology experts reviewed the reports for novelty, evidential support, follow-up priority, and confidence. In blinded comparisons against reports from single AI agents, experts preferred the multi-agent interpretations 75% of the time. The release does not say how many experts took part, whether model and resources were held fixed, or how many references each side cited.
The companies say the collaboration is expanding into joint drug-target discovery, using PerturbAI's causal data from living systems. That is a stated plan, not a confirmed disease mechanism, and the release does not describe how a lab would test the leads.
The atlas itself is earlier work. In March 2026 PerturbAI launched a discovery engine with an 8-million-cell, brain-wide CRISPR atlas, which the release says has been downloaded more than 40,000 times. The October claim is about reading that dataset in parallel, not about how the cells were perturbed.
Start with PerturbAI's October 21 release, then open the preprint and OpenAI blog post it points to and check the agent count, the 32-minute timing, and the 75% preference against what the release states.
