Show HN: LLM Council: survival-of-the-fittest multi-modal deliberation Developer moiz released LLM Council 1.0.0, an open-source tool that queries four frontier LLMs in parallel with distinct personas, anonymizes their responses, and uses a chairman model to synthesize a recommendation with a confidence score. The tool, available on GitHub under the MIT license, supports modes such as council, braintrust, researcher, and general, and costs $0.50–2.00 per full deliberation via OpenRouter. Multi-model structured deliberation. Queries 4 frontier LLMs in parallel with distinct personas, cross-pollinates anonymously, synthesises a recommendation. Install the council-of-claude skill: clone https://github.com/moiz-i/council-of-claude to ~/.claude/skills/council-of-claude, run ./scripts/setup.sh, and add my OpenRouter API key to ~/.council-of-claude/.env, invoke via /council git clone https://github.com/moiz-i/council-of-claude cd council-of-claude ./scripts/setup.sh export OPENROUTER API KEY="sk-or-v1-..." python3 scripts/council.py "Should we use Postgres or DynamoDB for our event store?" \ --context "Event sourcing, 10k events/sec, need ACID" \ --mode council Invoke skill via /council . 1. Stage 1 — Each model gets a persona and responds independently. No crosstalk. 2. Stage 2 — Responses are anonymized Response A/B/C and shown to all models. Each tags peers: ADOPT / MERGE / DEFEND / CHALLENGE. 3. Stage 3 — Chairman synthesises a recommendation with confidence score, consensus, dissent, and preserved gems. Anonymization in Stage 2 prevents brand bias. Convergence tags force genuine engagement instead of polite agreement. | Mode | Seats | Use for | |---|---|---| | council | Reframer, Devil's Advocate, Dreamer, Operator | Strategic decisions | | braintrust | Builder, Skeptic, Dreamer, Operator | Build/ship decisions | | researcher | Methodologist, Domain Expert, Critical Reviewer, Statistician | Research questions | | general | Pragmatist, Skeptic, Strategist, Architect | General problems | export OPENROUTER API KEY="sk-or-v1-..." required export COUNCIL MODELS="anthropic/claude-sonnet-4.6,openai/gpt-5.4,google/gemini-3.1-pro-preview,x-ai/grok-4.20" export COUNCIL CHAIRMAN="google/gemini-3.1-pro-preview" export COUNCIL CHRONICLE PATH="~/.council-of-claude/chronicle.md" Default uses 4 frontier models via OpenRouter.
