Hivemind

Hivemind is an open-source multi-model AI consensus platform that queries leading language models (GPT-5.2, Claude Opus 4.5, and Gemini 3 Pro) simultaneously to deliver synthesized, high-confidence responses. Designed for developers, researchers, and power users, Hivemind provides an MCP server that integrates with Claude Code CLI, as well as a full-featured web app with solo chat, multi-model consensus, and persistent conversation history. The system is particularly useful for situations where reliable, consensus-based AI outputs are needed and includes features such as prompt caching, secure key storage, and themed web UI.
