GPT realtime MINI calls tools incorrectly - Seems to be an error in the model

Hello Dear Team

Model: gpt-realtime-mini

We have an AI agent using gpt-realtime-mini

We ask the AI Transfer to “Person” as part of our routine tests.

We hear the model confirm and then dead silence. Call is still connected, but there is a dead silence. After sometime, Realtime model asks “Are you still there”…

When we check the log, we see that the model errored and called a tool differently than it did before.

It starts correctly calling the functions - you can see highlighted in red FUNCTION CALL: below

Suddenly, then the silence starts, it calls the function CALLFUNCTION: get_caller_info

It gives us the impression that the gpt-realtime mini version is not very good using tools.

Important: The second you change to gpt-realtime, (Same code, same build, same servers, same call, Same human testing, same speech utterance, same APIKEY - everything the same) the problem immediately goes away and all tools are called reliably.

Thank you so much and fully at your disposal for anything you need.

Hey @nbo2, thanks for the heads-up. We’re going to dig into this and see what might be causing it. If you’ve noticed any patterns or specific error messages, feel free to share them here, it really helps. We’ll post an update once we know more.
