The idea

Simulate a business decision before you make it. Open-source platform built for the lablab.ai × AMD hackathon.

How it works

Five agents run in a pipeline:

  1. Manager plans the analysis.
  2. Research agent checks the decision against company policies using retrieval.
  3. Operations agent runs it through a digital twin of the business.
  4. Finance agent runs a Monte Carlo simulation.
  5. Critic challenges the result.

The final recommendation goes to a human who approves or rejects, and that decision is written to an audit log.

Stack

FastAPI, Next.js, PostgreSQL, Redis and Docker Compose, with an LLM provider layer that runs the same code against OpenAI-compatible APIs or vLLM. In practice it ran Qwen2.5-7B served with vLLM on an AMD MI300X GPU. The same capabilities are exposed as MCP tools.
