**Model ID:** `sonar-deep-research`

Sonar Deep Research is a research-focused LLM designed for multi-step retrieval, synthesis, and reasoning across complex topics. It excels in conducting exhaustive research, autonomously searching and evaluating hundreds of sources, and generating comprehensive reports across various domains such as finance, technology, health, and current events\[1]\[3].
