OpenChiip Harness serves as an advanced framework for developers aiming to create self-hosted AI agents and orchestrate their workflows, whether they function independently or collaboratively. This innovative tool integrates large language model interactions, skill management, tool usage, multi-tiered memory systems, resource tracking, and teamwork among multiple agents, all presented through a user-friendly React-based admin dashboard. Users can operate it locally or link it to the OpenChiip platform to facilitate joint scheduling efforts. The system is equipped with a command-line interface, a web dashboard, an HTTP API, and a WebSocket interface, all of which enable effective management of chats, tools, sessions, memory, tasks, and performance monitoring. Additionally, it accommodates various model providers such as Baidu ERNIE and those compatible with OpenAI, along with the ability to delegate tasks to Codex or Claude Code. Installation options include pip, Docker, Linux packages, systemd, and Windows installers, while macOS users can also utilize pip for installation. The framework is distributed under the AIGCGPL-1.0 license, ensuring flexibility and openness for developers. With its comprehensive features, OpenChiip Harness is poised to significantly enhance the efficiency and effectiveness of AI agent workflows.
