Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

I keep getting the "API Error: Stream idle timeout - partial response received

Turn failed Try sending it again"

and at the same time I start the session with Opus 4.7 (1m) and it just switches to regular Opus 4.7

What Should Happen?

it should not give me this API error and definitely when the model is chosen should not switch unless I switch it. This was on the edge browser, I don't seem to be having these issues in Chorme

TL;DR

The issue can be mitigated by trying a different browser or checking the network connection to rule out any issues with the Edge browser.

Guidance

  • Try reproducing the issue in another browser, such as Chrome, to see if the problem is browser-specific.
  • Check the network connection to ensure it is stable and not causing the "Stream idle timeout" error.
  • Verify that the issue persists when sending simple requests to isolate if the problem is specific to complex requests.
  • Consider reaching out to the Anthropic API support for further assistance, as the issue may be related to their service.

Notes

The exact cause of the issue is unclear, and more information about the network setup and the specific requests being sent would be helpful in diagnosing the problem.

Recommendation

Apply workaround: Try using a different browser or checking the network connection, as this may resolve or provide more insight into the issue.
