Hi there! I’m trying to figure out how to change the model I’m using on the Android app. I keep finding all these responses about a “lightning icon.” I can’t find it anywhere, nor any other way to change my model. I’m not sure if this is a bug, or if it’s something that got updated away. Can someone please tell me where I’m supposed to find it, and if it’s gone, how I actually change the model? I keep wasting GPT-4o on things I could use GPT-4o mini for.
