Building a Multi-Agent Economy with Qwen2.5-3B: Engineering Report

用Qwen2.5-3B构建多智能体经济体：工程报告

A developer used Qwen2.5-3B to build a five-agent forest economy, and across 15 simulation rounds honey prices fell from 10 to 3, firewood rose from 4 to 7, and the Gini coefficient increased from 0.14 to 0.38.

Why it matters: HKR-H/K/R pass: the 3B multi-agent economy has a hook and concrete price/Gini results. It remains a single engineering experiment, not a product or framework launch, so it stays at the featured floor.
