Reranker using the Azure OpenAI

How can I use a reranker cohere model for search results from Azure AI Foundry .

Currently, I only see the direct API from Corehere.

Hey @hunglv53, You’re right — Azure AI Foundry doesn’t have a built-in reranker like Cohere’s. The usual way to handle this is in two stages:

  1. First-pass retrieval → use Foundry search to get your top-K candidate results.

  2. Second-pass rerank → send those candidates (as text) with the query to Cohere’s Rerank API, which will reorder them by relevance.

This way you keep Foundry for indexing/search and use Cohere only as a reranker. Direct integration isn’t there yet, so you’ll need to call Cohere’s API yourself after the Foundry query.
