Background

The Anthropic code execution bash tool provides a list of the generated files. This feature was missing from #9435 (although present in the zod schemas). It enables downloading generated files from the Anthropic API.

Summary

  • add response property file_id in code-execution-20250825
  • add example downloading file.

Example

Use code execution to have the AI ​​create an Excel file. Get the executed python code.
anthropic_code_execution_file_download

prompt:

Write a Python script to calculate fibonacci number and then execute it to find the 10th fibonacci number finally output data to excel file and python code.

package/anthropic

  • packages/anthropic/src/anthropic-messages-language-model.test.ts
    • add fixtures anthropic-code-execution-20250825.2 for file_id return pattern.
    • check the snapshot and file_id was included in the result.

examples/ai-core

  • add the examples, src/stream-text/anthropic-code-execution-20250825-downloads.ts
  • add the examples, src/generate-text/anthropic-code-execution-20250825-downloads.ts

examples/next-openai

  • fix /components/tool/anthropic-code-execution-view.tsx (add a download button)

Guys any documentation on how to download the said fileId ? Do we need to get it directly from anthropic ? or is there a way to seamlessly get it from AI SDK, the file ?

@vishnukool

Thanks for the question!

As far as I know, after you obtain the file_id from the AI SDK you need to call Anthropic’s Files API directly to download the file.

Here are examples that only use generateText / streamText:

  • examples/ai-core/src/generate-text/anthropic-code-execution-20250825-downloads.ts
  • examples/ai-core/src/stream-text/anthropic-code-execution-20250825-downloads.ts

And here is a Next.js example:

  • Next.js example 
    cd examples/next-openai
pnpm dev
# then open:
# http://localhost:3000/chat-anthropic-code-execution

The downloading route is here:
examples/next-openai/app/api/code-execution-files/anthropic/[file]/route.ts

I’m not sure there is dedicated documentation for this flow yet, but I’m confident that you can implement file downloads for code execution results in your app using this approach.

Does this help answer your question? 🙂
