Summary
Queries OpenAI, Google, and Anthropic APIs in parallel to synthesize consensus responses from multiple frontier models. Exposes tools for submitting questions to the hivemind, configuring API keys, checking provider status, and viewing token usage stats. When Claude is your MCP host, it orchestrates responses from GPT-5.2 and Gemini 3 Pro without needing an Anthropic key. Includes a deliberation algorithm that runs up to three refinement rounds when models disagree, with prompt caching to reduce costs on follow-ups. Useful when you want multiple model perspectives on difficult questions or need validation across different reasoning approaches.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Hivemind
Multi-model AI consensus platform that queries GPT-5.2, Claude Opus 4.5, and Gemini 3 Pro simultaneously to deliver synthesized, high-confidence responses.
MCP Server for Claude Code
Use Hivemind directly in Claude Code to get perspectives from GPT-5.2 and Gemini 3 Pro. Claude acts as the orchestrator and synthesizes the responses.
Requirements
- Node.js >= 18
- Claude Code CLI installed
- At least one API key: OpenAI or Google AI
Note: No Anthropic API key needed - Claude is already your host!
Installation
npm install -g @quantulabs/hivemind
claude mcp add hivemind -- hivemind
Configuration
You need at least one API key, but both are recommended for better consensus:
Option 1: Paste directly (recommended)
/hive-config sk-proj-xxx... # OpenAI key
/hive-config AIzaSy... # Google key
Option 2: Config file
Create ~/.config/hivemind/.env:
OPENAI_API_KEY=sk-...
GOOGLE_API_KEY=AIza...
# Optional: Override default models
OPENAI_MODEL=gpt-5.1
GOOGLE_MODEL=gemini-2.5-flash
A
.env.exampletemplate is included in the package.
Using with other MCP clients (non-Claude Code)
For standalone MCP usage, you can also add an Anthropic key to include Claude in the consensus:
ANTHROPIC_API_KEY=sk-ant-...
Disable Claude Code mode via /hive-config > Settings > Claude Code Mode.
Usage
/hive "Why is my WebSocket connection dropping?"
Claude orchestrates the consensus from GPT-5.2 and Gemini 3 Pro responses.

Automatic Hivemind Fallback
Copy CLAUDE.md.example to your project's .claude/CLAUDE.md to enable automatic Hivemind consultation when Claude is stuck (after 3+ failed attempts).
Prompt Caching
All providers use optimized caching for cost reduction on follow-up queries:
| Provider | Type | Savings | Min Tokens |
|---|---|---|---|
| OpenAI | Automatic | 50% | 1024 |
| Gemini 2.5+ | Implicit | 90% | - |
| Anthropic | Explicit | 90% | 1024 |
Web Interface
A full-featured web app with solo mode, hivemind mode, and conversation history.
Quick Start
# Clone the repository
git clone https://github.com/QuantuLabs/hivemind.git
cd hivemind
# Install dependencies (requires Bun >= 1.0)
bun install
# Start development server
bun dev
Open http://localhost:3000, click the settings icon, and enter your API keys.
Features
- Multi-Model Consensus: Query 3 leading AI models simultaneously
- Deliberation Algorithm: Up to 3 rounds of refinement to reach consensus
- Solo Mode: Chat with individual models (GPT, Claude, Gemini)
- Hivemind Mode: Get synthesized responses from all models
- Conversation History: Persistent chat sessions
- Dark/Light Theme: Full theme support
- Secure Storage: API keys encrypted with AES-GCM in browser
Security
- API keys are encrypted using AES-GCM with PBKDF2 key derivation
- Keys are stored locally in browser localStorage (never sent to servers)
- Session persistence uses sessionStorage (cleared on browser close)
How Consensus Works
- Initial Query: All 3 models receive the same question
- Analysis: An orchestrator analyzes responses for agreements/divergences
- Refinement: If no consensus, models see other perspectives and refine (up to 3 rounds)
- Synthesis: Final response synthesizes agreed points and addresses divergences
Supported Models
OpenAI
- GPT-5.2 (default)
- GPT-5.1, GPT-5, GPT-5 Mini, GPT-5 Nano
- O4 Mini
Anthropic
- Claude Opus 4.5 (default)
- Claude Sonnet 4.5, Claude Opus 4, Claude Sonnet 4
- Gemini 3 Pro (default)
- Gemini 3 Flash, Gemini 2.5 Pro/Flash/Flash Lite, Gemini 2.0 Flash
