Earlier this year, we ran experiments to test the limits of scaling agents to cooperate toward a goal. Our hypothesis was that this would unlock a new tier of task scale and complexity. The flagship project was a long-running swarm building a web browser from scratch . It succeeded as a proof of concept, but fell far short of polished software. That work was deliberately empirical. We started from a blank canvas and hill-climbed toward a stable, effective system . Since then, our goal has been to understand the agent swarm well enough to engineer it deliberately. To test that progress, we returned to a task the old swarm had struggled with: building SQLite from scratch, in Rust, from nothing but its documentation. Our initial results have been promising. We ran the old and new swarms on the same task, with the same models and the same time budget, and measured how much of a held-out SQL test suite each could pass. The new swarm did better in every model configuration.…
