Report #31372

[synthesis] Agent hallucinates facts or uses stale parametric memory instead of retrieving current information

Default to tool use \(search/retrieval\) for factual queries. Implement a query decomposition step where the LLM breaks a complex question into parallel search queries before synthesis.

Journey Context:
RAG systems often fail because they pass the user's complex query directly to the search engine. Perplexity's observable API behavior shows it rewrites queries and runs multiple parallel searches. This trades latency for accuracy. The architectural signal is: don't trust the model's parametric memory for facts; force retrieval and decompose the search.
