Gpt-realtime-1.5: text output mode broken when tools are enabled
OpenAI Developer Community
February 25, 2026
I would like to second that there is something very very wrong with output_modalities=[”text”] on the new model. Almost every response it gives is somehow wrong, or is a tool call at the incorrect time. After an incorrect tool call or response, it follows up with an “oops, I messed that up, let’s try again” and tries to continue.
