Limitations & when to consider alternatives

Known limitations

  • Conversational Agent access may require enablement. The Conversational Agent API requires access to be enabled for the index; otherwise conversational endpoints return a 403 error.
  • Image uploads have size and format limits. Conversational image uploads allow up to five images per request, with formats and maximum sizes specified by Marqo.
  • Uploaded conversational images expire. Uploaded images are retained for 24 hours and then deleted.
  • Conversation history is retained for a limited period. Conversations are kept for 30 days after their last activity, and only the 100 most recent turns are stored and returned.
  • Search result pagination is capped. For search, composite search, and collections, limit plus offset must not exceed 10,000.

Look elsewhere when

  • You need a native mobile app rather than an API for embedding into a mobile storefront.
  • You need a browser extension or desktop installer rather than a cloud API and storefront integration.
  • You need document or spreadsheet uploads rather than image inputs.
