This package provides two research modes: an IterativeResearcher for shorter reports using continuous refinement loops, and a DeepResearcher for thorough structured research. It uses a multi-agent architecture where specialized agents collaborate to investigate topics from multiple angles. The system is compatible with OpenAI, Anthropic, Gemini, DeepSeek, and local models like Ollama, and includes optional tracing for LLM and tool call observability.
