FIM One

FIM One is an open-source agent platform designed for enterprises operating across global and China regions. It integrates disparate systems—ERP, CRM, HR, finance, databases, and messaging platforms—through a single AI agent core, eliminating the need to replace existing infrastructure. The platform supports three modes: standalone AI assistant, embedded copilot, and central orchestration hub.

Key features include multi-step tool calling with ReAct reasoning, DAG-based execution planning with parallel processing, and human-in-the-loop review for write operations. Users can self-host with any LLM provider, or use the managed cloud version. The project is built with Claude AI coding tools and is available on GitHub.
