FastGPT is an open-source platform for building AI agents and knowledge-base applications. Teams assemble agents by stacking blocks in a visual workflow editor with a rich API ecosystem, ground answers in an enterprise knowledge base that uses hybrid retrieval to reduce hallucinations, and connect any model. Debugging and auditing tools cover the full LLM lifecycle, and SSO and role-based access control support a secure enterprise portal. The project has more than 28,000 GitHub stars and is used by over 1,000 enterprises, with private deployments available.
FastGPT serves enterprises and the developers inside them who want controllable, production-grade agents rather than a hosted chatbot. Sales operations teams use it for real-time rep assistance and training, support teams for ticket routing and customer service, HR teams for resume screening, and finance teams for expense review and market reports. Companies that need hands-on help can buy expert consulting, implementation support and enterprise customization. Open-source users can start from community templates and documentation, which keeps ramp-up fast for technical teams.
A support team can run an AI customer service assistant that answers thousands of inquiries daily, with a reported 42% drop in human handoffs. A recruiter can have the system read large volumes of resumes, score matches and surface top candidates. A finance team can snap a receipt and have the agent check budgets and rules and flag anomalies. A fund team can generate daily market reports with charts from templates. An R&D organization can deploy a knowledge assistant to shorten new-hire training, and developers can embed agents in their own product through the API.
