Hi! We, Vincenzo and Riccardo, built Doxa as an agnostic engine for emergent simulations with agents for constrainted scenarios (like geopolitical, economics, ...) and work well with LLMs like Qwen2.5:7B, Llama but also cloud models such as Gemini.

Doxa can be configured in minutes with YAML scenarios, where you can assign agents' persona, portfolios, constraints.
