Exa, an AI search API company, has significantly upgraded its Highlights feature, enabling it to generate concise, query-relevant summaries from web pages in real time. The new Highlights can produce 500-character summaries that match the accuracy of 8,000-character full texts, reducing token consumption by 16 times. This improvement is particularly effective for long documents like technical guides and research papers, where 500-character Highlights achieve 60% accuracy compared to 6% for full texts. The upgrade is implemented at the model level, benefiting all requests with the enableHighlights parameter without requiring code changes.
