MIT's AI agent society experiment reproduced on four RTX 3090 GPUs
A HAL8 team working with Apex Fusion reran MIT's SwarmWorld experiment using open-weight Qwen3.8-27B at 4-bit precision on four consumer RTX 3090 GPUs. The run took about 26 hours and 12,800 model calls; nine of 12 paired effects matched MIT's direction, and the agent society hit all 16 research milestones versus 6 for a solo agent.
- 9 of 12 paired effects matched MIT's direction; the other three fell within noise
- Solo Qwen3.8-27B reached 6 of 16 milestones, the society reached all 16 (MIT: 14)
- The run took ~26 hours and 12,800 model calls on four RTX 3090s
- KV cache precision shifted results more than the gap between 27B and 235B models
