FastGPT AI is an open-source knowledge-base question-answering system based on large language models, designed to help enterprises or individuals build personalized intelligent Q&A assistants, enabling efficient knowledge management and automated decision-making.
It supports uploading PDFs, Word documents, and other formats, can automatically perform text preprocessing, vectorization, and QA segmentation, and can be manually adjusted and optimized to quickly build a structured, personalized knowledge base.
FastGPT AI can connect to multiple LLM APIs, including OpenAI, Alibaba Cloud, Zhipu AI, and iFlytek Spark. If using domestic models, it is recommended to manage centralized forwarding via the One API middleware.
Its open-source version supports free private deployment, with code hosted on GitHub. If used for commercial multi-tenant SaaS services or involves copyright, please contact the author for the appropriate license.
By designing complex Q&A flows with a drag-and-drop interface, it enables querying databases, invoking external systems, automating tasks (such as summarizing GitHub Issues), and supports looping nodes to improve batch processing efficiency.
Its API interface is aligned with the OpenAI format; existing applications typically only need to modify the BaseURL and Authorization to quickly connect, and it can be integrated into Enterprise WeChat, WeChat Official Accounts, and Feishu.
