We’re excited to introduce "fast", a new depth value for the Linkup Search endpoint. "fast" is our sub-second search mode, optimized to provide accurate results and snippets in the lowest possible time. "fast" works best with focused queries, where you’re looking for one specific piece of information.

​
What’s new

"fast" uses a simpler, more direct search pipeline than "standard" or "deep". The key difference is scope:
  • "fast": one piece of information, one direct answer. Best for short, focused prompts. Only search results and relevant content snippets are returned.
  • "standard": best to handle several topics, data sources (general web search, financial data, LinkedIn public data), or retrieve fully scraped content of a URL provided in the query.
This makes "fast" ideal for conversational use cases, real-time lookups, and high-volume pipelines where latency is critical.
The "fast" depth is currently in beta. We welcome any feedback. Reach out on Discord or at support@linkup.so.

​
How to use

A simple rule of thumb: if your prompt is short and you’re looking for one specific thing, use "fast". If your prompt is longer or spans multiple topics, use "standard".
