We use openai-agents-js (default Responses API) to run our Multi-Agent Systems (MAS). During MAS runs, we intermittently hit the following error:
{
"error": "TypeError: terminated"
}
We’ve seen this issue for a long time, but the frequency has increased significantly over the last 2 days. It happens in both streamed and non-streamed MAS runs.
We use the gpt-4.1 and gpt-5 model families across our MASes.
Full error (from our logs):

Because the SDK uses the Responses API by default, this may be related to the following thread:
This issue may also be related:
And this is the corresponding “twin” issue in the openai-agents-js repository:
If there are any known incidents, rate limits, networking changes, or recommended client settings for these model families that could explain the recent increase, we’d appreciate any guidance. We’d also like to understand whether this error is caused by our system (e.g., timeouts/aborts/network/proxy behavior) or if it’s originating from the OpenAI backend.
