Do you know how I could use ChatGPT or anything like that to upgrade Alexa/Cortana?

I'm hoping to improve Alexa's&Cortana's smart home capabilities. Make one or both of them capable of controlling my PS4 or PS5 and make them more compatible with devices they already control. I'm also hoping to do this kind of stuff with them: [(378) Meet Jarvis: My GPT-4 Code Assistant - YouTube](https://www.youtube.com/watch?v=NxZgl2bK_l8)


in short I'm wondering if there is any free way to make a little bit cortana/alexa more like J.A.R.V.I.S.
