GraphRAG-SDK v0.2 introduces significant enhancements designed to elevate the development of knowledge graph-based AI applications, offering features such as multi-model support, auto-ontology discovery, expanded data source compatibility, and multi-agent systems. This version supports both Google's Gemini and OpenAI's GPT models, allowing users to seamlessly switch between them for optimized performance. The auto-ontology discovery feature simplifies the management of multiple knowledge graphs by automatically generating ontologies, thereby reducing manual setup time. Additionally, the SDK now supports data ingestion from URLs, CSV, and JSON formats, streamlining the integration of diverse data sources. The multi-agent system, complete with an orchestrator, facilitates the coordination of different agents specializing in distinct tasks, making it easier to build complex AI-driven ecosystems. These updates collectively enhance the flexibility, efficiency, and scalability of AI workflows, enabling users to create more sophisticated and accurate knowledge graph applications.
