Swarm Research

A recursive multi-agent research system that turns ambiguous questions into evidence-backed, auditable answers.

27Agents
119MTokens
73Unique domains

Swarm architecture / Different workloads

One control plane. Multiple forms of hard work.

From low-level GPU kernels and end-to-end inference engines to multi-domain research, each product uses agent swarms to divide work, preserve evidence, and verify results.
