Describe the feature or improvement you're requesting

Please Update Realtime API code documentation example as the default model is 1-10-2024, please let the default is the newest model. I surprised that I have been charged a lot and I didn't realize that I am using the old version which costs higher, so please make sure you update the code examples to use the newest version
