FastGPT serves as a comprehensive AI agent development and deployment framework designed to simplify the creation of intelligent, knowledge-driven applications. It integrates data connectors for ingesting documents, databases, and APIs, performs preprocessing and embedding, and invokes local or cloud-based models for inference. A retrieval-augmented generation (RAG) engine enables dynamic knowledge retrieval, while a drag-and-drop visual flow editor lets users orchestrate multi-step workflows with conditional logic. FastGPT supports custom prompts, parameter tuning, and plugin interfaces for extending functionality. You can deploy agents as web services, chatbots, or API endpoints, complete with monitoring dashboards and scaling options.
