Choose your path: Consilium can be used through the web app (no setup) or via the SDKs and CLI for engineers. Pick the approach that fits your workflow.
For Users: Web App
Sign up at myconsilium.xyz. Authentication is handled by Clerk with support for email, Google, and GitHub sign-in methods. Your account gives you access to the deliberation dashboard, debate history, analytics, and API key management.
Consilium uses a Bring Your Own Keys model. Navigate to Settings and add API keys for the providers you want to use. All keys are encrypted with AES-256-GCM before storage — they are never stored in plaintext or logged. You need at least one provider key, but using 2-3 different providers gives you genuine model diversity in debates.
No keys? Consilium automatically falls back to Groq's free tier models (Llama 3.1 8B, Llama 3.3 70B, Llama 4 Scout) when no paid keys are configured.
Go to the Council page. Enter your topic or question, select a deliberation mode (Council is the default), and choose 2-5 AI models. Click "Start Deliberation" and watch the debate unfold in real-time via Server-Sent Events streaming.
You'll see each phase live: models proposing independently, cross-examining each other, defending their positions, voting, and finally synthesizing a consensus answer.
Every deliberation produces a rich set of outputs:
Golden Prompt — The synthesized final answer integrating the strongest arguments from all models
Confidence Scores — Per-model calibrated confidence based on explanation stability (how much each model changed its position under pressure)
Dissent Report — Majority and minority positions identified via agglomerative clustering. Shows where models agreed and where they fundamentally disagreed
Vote Results — Condorcet winner (if any), Borda scores, full ranking. Shows which position won and by what margin
Audit Trail — Every step recorded: model, input, output, tokens used, cost, latency. Full transparency into how consensus was reached
Cost Breakdown — Per-model, per-round cost tracking with total cost and token usage
Export results as Markdown, .cursorrules files, plain text, or copy to clipboard.
For Engineers: SDK & CLI
npm install -g @myconsilium/cliOr with yarn/pnpm:
yarn global add @myconsilium/clipnpm add -g @myconsilium/cli
consilium loginOpens your browser for Clerk authentication. On success, a CLI token is stored in ~/.consilium/config.json. Alternatively, set the CONSILIUM_API_KEY environment variable.
