Batch API Task Runs Repeatedly with gpt-5.2-pro

I’m experiencing the same issue described in the other thread Batch api Task runs repeatedly.

When I run a Batch API task using gpt-5.2-pro, even with only two queries in the job, the logs show that the tasks appear to run repeatedly. The cost keeps increasing during the process, so I end up having to cancel the batch job to stop the spending.

Resubmit a job with only one request, still encountering the same issue: the logs show multiple same requests, and cost me $20 (the same request I ran without batch mode is ~$2).

This time I let it run over, and after 10 hours, it failed with following empty error information…

{“id”: “batch_req_695f7ab53af081909f8093a3d1b36e74”, “custom_id”: “124904021”, “response”: {“status_code”: 0, “request_id”: “”, “body”: {}}, “error”: null}

I am pretty sure this is a similar issue as this previous post Batch api Task runs repeatedly

Hey @cfybasil , Apologies for the inconvenience this is causing. We are not able to find any information using the request id you shared. Would you please be able to provide a newer more latest request id where you are seeing this behaviour and we can take a look at it. Thank you!

How about batch_695eebbf78b88190aeedd428228f5e4c?
