Query Refinement And Correction

via “iterative-query-refinement-with-feedback-loops”

Sonar Deep Research is a research-focused model designed for multi-step retrieval, synthesis, and reasoning across complex topics. It autonomously searches, reads, and evaluates sources, refining its approach as it gathers...

Unique: Implements query refinement as an internal reasoning loop where the model evaluates search result quality and autonomously decides whether to reformulate, rather than exposing refinement as a user-facing interaction

vs others: More adaptive than single-pass search APIs; more autonomous than systems requiring explicit user feedback between search iterations
