Contextual Search Query Generation From Page Content

via “context-aware search query formulation”

GPT-4o Search Previewis a specialized model for web search in Chat Completions. It is trained to understand and execute web search queries.

Unique: Search query formulation is implicit and trained into the model weights rather than explicit (no separate query-generation step or function call); the model learns to recognize search-worthy intents from conversational context and reformulate queries for optimal retrieval during training.

vs others: More natural and context-aware than rule-based search triggers, but less transparent and debuggable than explicit query-generation agents with separate LLM calls for query refinement.
