Microsoft foundry(new)

Question

am using azure-ai-projects==2.0.0b3 and invoking agents using responses.create() with agent_reference.

I need to attach .xlsx or .csv files to Code Interpreter container when creating the response. I upload the file using the OpenAI file API and obtain the file_id.

However, I cannot find any parameter in responses.create() or conversation.item.create() with agent_reference to pass the file_id.

in the microsoft foundry classic SDK shows file attachments using MessageAttachment and tools=[CodeInterpreterToolDefination. but microsoft foundry new SDK doesnt have that atachment option.

Could you please point to the documentation that explains how to pass a file_id when using agent_reference, or confirm if this capability is not currently supported?

Answer 1

This capability is not documented as supported in the new Microsoft Foundry agents experience when using responses.create() with agent_reference.

In the classic model, files could be attached to a thread message (for example via MessageAttachment), which then became available to tools like Code Interpreter or file search on that thread-specific vector store. In the new model:

• responses.create() is a simplified, synchronous execution API that takes input, optional conversation, and an agent_reference in extra_body.
• The available documentation for tools focuses on:
  • File search, where files are uploaded, added to a vector store, and then attached at the agent or conversation level, not passed as file_id parameters on responses.create().
  • Code Interpreter, where troubleshooting covers upload/download of files via annotations and containers, but does not describe any file_id argument on responses.create() or conversation item creation.

The provided references show how to:

• Upload files and create vector stores for file search, including the requirement purpose="assistants" and supported file types such as .csv (as text/plain or text/csv-compatible) and .pdf, .json, etc., but only in the context of file search and vector stores, not Code Interpreter containers.
• Use the new responses.create() API with agent_reference for executing agent logic, without any documented mechanism to attach files by file_id in the request body.

Because no parameter or pattern is documented for passing file_id into responses.create() or conversation.item.create() with agent_reference, and the only file-handling patterns described are:

• File search via vector stores attached to agents or conversations, and
• Classic agents/threads with message attachments,

the ability to directly attach uploaded files to a Code Interpreter container at responses.create() time is not currently documented or supported in the new agents SDK.

The supported and documented file-related options in the new experience are:

1. Use file search: upload files, create a vector store, and attach it to the agent or conversation so the agent can retrieve content from those files.
2. For Code Interpreter, rely on the tool’s own file upload/download flow via annotations (for example container_file_citation), not via a file_id parameter on responses.create().

Answer 2

upload a file to Code Interpreter after an agent creation with Code Interpreter.

Answer 3

upload a file to Code Interpreter after an agent creation with Code Interpreter.

Answer 4

Do we have anyway to attach the uploaded fileid (which is .xlsx file uploaded to openai) attach with user query ?
