New tools and features in the Responses API

Re:New tools and features in the Responses API by beklein on Wednesday May 21, 2025 @02:04PM (#44054325)

On the announcement page they are saying that "...introducing updates to the file search tool that allow developers to perform searches across multiple vector stores...". On the docs, I still find this limitation: "At the moment, you can search in only one vector store at a time, so you can include only one vector store ID when calling the file search tool."

Anybody knows how searching multiple vector stores is implemented? The obvious plan would be to allow something like:

  "vector_store_ids": ["<vector_store_id1>", "<vector_store_id2>", ...]

sorry about the error in the docs. we're removing that call out.

`"vector_store_ids": ["<vector_store_id1>", "<vector_store_id2>"]` is exactly right. only 2 vector stores are supported at the moment.

2 feels quite arbitrary and honestly not that much of an improvement. Any plans to up that limit?
