What they did and found
In ProgramBench tasks, increasing agent count from 1 to 128 improved mean final pass rate by about 49% (19.31% to 28.78%), and extending to 1,024 agents raised pandoc’s final pass rate to 55.06% (from 33.89%). The gains accompany emergent self-organized cooperation patterns and no central orchestrator, with earlier highs at larger scales.
Why it matters
Shows scaling the number of agents as a distinct dimension for organizational intelligence, offering faster progress on hard tasks, but results depend on task type, budget, and implementation details.
Agensh runs a cooperation loop where workers gather context, claim sub-tasks, take action, verify results, and merge progress into a shared workspace. The infrastructure,shared workspace, message interface, and shared context,lets many workers contribute asynchronously, reducing bottlenecks.
Two-paragraph takeaway: more agents can improve both final results and speed on challenging tasks, but scale brings coordination challenges and requires robust workflows; benefits vary by task, budget, and model used, so teams should test incrementally.

What remains uncertain
Limited to five tasks, fixed budget and model; results may not generalize to other tasks or settings.
