Azure Cognitive Search AMA: Vector search, Azure OpenAI Service, generative apps, plugins & more

Adding to Liam's answer, if you are only using vector search to retrieve documents, and not passing those documents to an Azure OpenAI prompt, then the usage of vector search by itself will not result in any calls to Azure OpenAI. Meaning, once you've generated the vector embeddings for your content (which will consume token counts in the embedding model/endpoint), there are no further costs beyond the search service itself. It's only when you pass the retrieved documents where additional costs can come into play.
