We're excited to announce R2R v3.5.0, featuring our new Deep Research API and significant improvements to our RAG capabilities.
🚀 Highlights
- Deep Research API: Multi-step reasoning system that fetches data from your knowledge base and the internet to deliver comprehensive, context-aware answers
- Enhanced RAG Agent: More robust with new web search and scraping capabilities
- Real-time Streaming: Server-side event streaming for visibility into the agent's thinking process and tool usage
✨ Key Features
Research Capabilities
- Research Agent: Specialized mode with advanced reasoning and computational tools
- Extended Thinking: Toggle reasoning capabilities with optimized Claude model support
- Improved Citations: Real-time citation identification with precise source attribution
New Tools
- Web Tools: Search external APIs and scrape web pages for up-to-date information
- Research Tools: Reasoning, critique, and Python execution for complex analysis
- RAG Tool: Leverage underlying RAG capabilities within the research agent
