Artificial intelligence is evolving rapidly, but most AI tools still follow a familiar pattern: you provide a model with a prompt, and it generates a response.
Recently, a new approach has emerged: multi-agent simulations. In these systems, many autonomous AI agents interact within a shared digital environment. Instead of a single model producing an answer, these simulations model groups of agents exchanging information, forming opinions, and influencing each other.
A prominent open-source project in this space is MiroFish, a swarm intelligence engine designed to simulate real-world scenarios using thousands of AI agents. Its core goal is to provide a digital sandbox for exploring complex events—such as financial markets, public opinion shifts, and policy reactions—before they occur in reality.
💡 Building or interacting with AI agents and MCP servers? Apidog provides a powerful, built-in MCP Client for debugging and testing MCP Servers. Connect via STDIO or HTTP, test executable Tools, Prompts, and Resources visually, and handle OAuth 2.0 and rich Markdown/image responses—streamlining MCP integration testing.
Unlike traditional AI that outputs an answer directly, MiroFish builds a digital society of AI agents. Each agent has its own memory, personality traits, and decision logic. When you introduce an event—such as breaking news or a market signal—the agents interact and influence each other’s behavior.
Over time, these interactions form emergent patterns, revealing possible outcomes or sentiment shifts. This makes MiroFish a powerful environment for experimentation and forecasting.

What Is MiroFish?
MiroFish is a swarm intelligence simulation engine based on multi-agent AI. Instead of one model, it generates a population of autonomous agents within a simulated environment. Each agent represents a participant in this virtual society, with:
- Personality traits
- Behavioral rules
- Long-term memory
- Social relationships
- Decision-making processes
As agents interact—exchanging information and responding to events—emergent behavior occurs, i.e., system-level patterns arise from individual actions.
By simulating these interactions, MiroFish models how real-world events may unfold, acting as a sandbox for 'what-if' scenarios.
The Vision: A Mirror of Collective Intelligence
MiroFish aims to be a collective intelligence mirror of the real world. Traditional predictive systems rely on historical data and statistical models, but often fail when human behavior is unpredictable or socially driven.
Key examples:
- Financial markets swayed by investor sentiment
- Unpredictable social media trends
- Rapidly shifting public reactions to policy
MiroFish takes a different approach: it recreates a digital environment where simulated agents interact and influence one another. Observing these interactions can yield insights into potential real-world outcomes.
From Seed Data to a Digital World
To run a simulation, start with seed material—the information defining your scenario. This can include:
- News articles
- Financial or policy reports
- Research papers
- Social media discussions
- Fictional stories
Upload your material and describe your prediction goal in natural language. Example use cases:
- Simulate market response to a new policy
- Model public reaction to a statement
- Predict how a narrative might evolve
MiroFish then builds a parallel digital world where agents interact according to your scenario.
MiroFish Workflow: Simulation Pipeline
MiroFish transforms seed data into a dynamic simulation via several stages:
1. Knowledge Graph Construction
- Extracts entities and relationships from data sources (news, financials, policies, discussions).
- Builds a GraphRAG-based knowledge graph to structure information for the simulation.
- Injects both individual and group memory structures so agents retain historical context.
2. Environment Generation
- Extracts entities/relationships
- Generates agent personas
- Builds social networks
- Configures simulation parameters
Agents are assigned identities, backgrounds, and behavioral rules to reflect realistic social dynamics.
3. Parallel Simulation Execution
- Agents operate simultaneously, responding to events and interacting.
- The platform supports thousands of agents across parallel systems.
- Agents interpret prediction requests, simulate social interactions, update memory, and dynamically evolve the environment.
4. Report Generation
After multiple simulation cycles, a specialized agent—ReportAgent—analyzes the results, producing structured reports that summarize:
- Key outcomes
- Trends
- Behavioral insights
- Risks
This helps users interpret simulation results and anticipate real-world implications.
5. Deep Interaction
Users can interact directly with the simulated world:
- Communicate with individual agents
- Query their decisions and motivations
- Explore group dynamics
- Engage with ReportAgent for deeper analysis
This interactive capability sets MiroFish apart from static forecasting tools.
Quick Start: Running MiroFish Locally
You can deploy MiroFish locally via source or Docker. Here’s a practical setup guide.
System Requirements
Ensure the following tools are installed:
| Tool | Version | Purpose |
|---|---|---|
| Node.js | 18+ | Frontend runtime |
| Python | 3.11–3.12 | Backend runtime |
| uv | Latest | Python package manager |
Check installations:
node -v
python --version
uv --version
Step 1: Configure Environment Variables
Copy the sample config:
cp .env.example .env
Edit .env and add required API keys.
LLM API Configuration
MiroFish supports any OpenAI SDK-compatible API.
Example:
LLM_API_KEY=your_api_key
LLM_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1
LLM_MODEL_NAME=qwen-plus
Recommended: Use the Qwen model from Alibaba’s Bailian platform.
For large simulations, start with fewer than 40 rounds to manage compute resources.
Memory System Configuration
MiroFish uses Zep Cloud for agent long-term memory.
Example:
ZEP_API_KEY=your_zep_api_key
Zep Cloud’s free tier suffices for small experiments.
Step 2: Install Dependencies
Install all dependencies at once:
npm run setup:all
Or install separately:
Frontend:
npm run setup
Backend (creates Python virtualenv):
npm run setup:backend
Step 3: Launch the Platform
Start both services:
npm run dev
Default URLs:
- Frontend: http://localhost:3000
- Backend: http://localhost:5001
To run only backend:
npm run backend
To run only frontend:
npm run frontend
Docker Deployment
For containerized environments:
-
Configure environment variables as above:
cp .env.example .env -
Start containers:
docker compose up -d
Default ports:
- 3000: Frontend UI
- 5001: Backend API
Docker config includes optional mirror sources for faster image downloads.
Final Thoughts
Swarm intelligence platforms like MiroFish represent a step toward simulating complex social environments. Imagine testing policies before launch, anticipating market reactions, or studying information spread across networks—all inside a controllable simulation.
No simulation can fully capture real human complexity, but MiroFish demonstrates how AI can move beyond Q&A and begin modeling societal dynamics. As multi-agent simulation advances, tools like MiroFish may become essential for predictive analysis and digital experimentation.
