MiroFish: The Open Source Swarm Intelligence Engine That Simulates the Future

Imagine being able to run the future before it happens. Not as a statistical forecast or a gut feeling, but as a living simulation where thousands of autonomous AI agents carry individual personalities, memories, and social relationships, and play out scenarios in a compressed digital sandbox. You upload the seed material, whether that is a news article, a policy draft, or the opening chapters of a novel, and MiroFish returns a detailed prediction report along with an interactive world you can continue to question. That is what MiroFish is. Built by a small team backed by Shanda Group, one of China's oldest internet companies, MiroFish is an open source, self-hosted Swarm Intelligence Engine that combines multi agent AI simulation, knowledge graph construction using GraphRAG, and long-term agent memory. As of March 2026, the GitHub repository has over 32,300 stars and 4,100 forks, putting it among the most watched AI projects of the year. 1. What Is MiroFish? MiroFish describes itself
