About

What is Concilium?

Concilium is an open-source, local-first AI tool designed to solve the problem of inconsistent answers from different large language models (LLMs) for coding tasks. It allows users to send a single prompt to multiple agents like Claude, OpenAI, and OpenCode, which then run in parallel. The tool employs a three-stage consensus process: parallel execution, blind peer review by juror models, and synthesis by a chairman model. This approach ensures a validated, high-quality answer, combining the best aspects of each model's output. Available as a CLI and a desktop app for macOS and Linux, Concilium also offers built-in analytics for tracking token usage, costs, and model performance, all computed locally without data leaving the machine. A cloud version with team collaboration and API access is also planned.

Best used for

Ideal for developers who need to generate robust code, refactor existing implementations, and add complex features like authentication or rate limiting. Especially valuable for those seeking to leverage multiple LLMs for better answers while maintaining data privacy and optimizing costs.

FAQs

What LLMs does Concilium support for parallel execution?

Concilium supports OpenAI, Claude, and OpenCode for parallel execution. It also uses OpenRouter to access various models for the peer review and synthesis stages, allowing for flexibility in model selection for different parts of the deliberation process.

Does Concilium store my code or prompts in the cloud?

No, Concilium is designed to be local-first. All analytics, run history, and deliberation data are computed and stored locally on your machine. No data ever leaves your device, ensuring privacy and control over your sensitive code and prompts.

Can I use Concilium in my CI/CD pipeline or scripts?

Yes, Concilium offers both a CLI interface and a programmatic API. You can run deliberations directly from your terminal, pipe results to other tools, or embed the deliberation engine into your scripts and CI/CD pipelines with a simple function call.

What kind of analytics does Concilium provide?

Concilium provides a detailed analytics dashboard that tracks token usage, costs, timing, and model rankings. You can see token breakdown by model, cost per run, model win rates, and a full run history, helping you optimize your AI workflow.
