Exa's Dynamic Highlights returns passages selected for the current query instead of requiring an agent to ingest every retrieved page in full. The output is designed to preserve the relevant span and enough surrounding context to make it usable downstream.
The change moves token selection into the retrieval service. That can reduce prompt volume and repeated parsing when an agent needs evidence from many pages, while keeping a source URL available for verification.
The vendor announcement does not prove that extracted passages preserve every caveat or outperform full-document reading on all tasks. Teams should compare recall, citation fidelity, and failure behavior on their own queries before treating context savings as retrieval quality.
