Sudden increase in /v1/responses timeouts on gpt-4.1-mini (stable for months, started recently)

Hi @lastround360, that’s frustrating, especially when it was working before.
This lines up with the recent Responses API outage that caused elevated timeouts earlier. It’s been resolved now, so things should be stabilizing.
Can you confirm if you’re still seeing timeout errors on your end?
Also worth checking the status page in case anything pops up again: https://status.openai.com
If it’s still happening, share what you’re seeing and we can dig a bit deeper.
