Hey everyone,

We started receiving Model not found o4m-sonic-o-api-ev3 error on 26 March 2026 14:30 UTC. We constantly got this error for GPT-4o and GPT-4.1 models with web search tool. We checked the OpenAI Status but could not see any issue that describes this one.

Have you guys ever encountered an error like this before?
Thanks in advance.
