ChatGPT Integration with Siri - Current Status and Possibilities

I've heard about Apple's plans to integrate ChatGPT with Siri, and I have a few questions about this:

1. Has Apple officially released any ChatGPT integration with Siri?
2. Is there a way to use ChatGPT directly instead of Siri on iOS?
3. Is there any setting to forward Siri queries directly to ChatGPT?

I'm interested in knowing both official and third-party solutions if available. Has anyone successfully set up something like this on their iPhone?

I'm currently running iOS 18.3 and would appreciate any information about:

• Official integration status
• Available alternatives or workarounds
• Any upcoming features you might know about

Thanks for your help!

Best regards
