Depends on what AI you're looking for. I don't know of an LLM (a language model,think chatgpt) that works decently on personal hardware, but I also haven't really looked. For art generation though, look up automatic1111 installation instructions for stable diffusion. If you have a decent GPU (I was running it on a 1060 slowly til I upgraded) it's a simple enough process to get started, there's tons of info online about it, and it's all run on local hardware.

Ollama with ollama-webui. Models like solar-10.7b and mistral-7b work nicely on local hardware. Solar 10.7b should work well on a card with 8GB of vram.
I can run a pretty alright text generation model and the stable diffusion models on my 2016 laptop with two GTX1080m cards. You can try with these tools:

Yeah if your willing to carry a brick or at least a power bank (brick) if you don't want it to constantly overheat or deal with 2-3 hours of battery life. There's only so much copper can take and there are limits to minaturization.
It's not like that though. Newer phones are going to have dedicated hardware for processing neural platforms, LLMs, and other generative tools. The dedicated hardware will make these processes just barely sip the battery life.
if that existed, all those AI server farms wouldn't be so necessary, would they?
dedicated hardware for that already exists, it definitely isn't gonna be able to fit a sizeable model on a phone any time soon.
models themselves require multiple tens of gigabytes of storage space. you won't be able to fit more than a handful on even a 512gb internal storage. the phones can't hit the ram required for these models at all. and the dedicated hardware still requires a lot more power than a tiny phone battery.
And I do have a couple different LLMs installed on my rig. But having that resource running locally is years and years away from being remotely performant.
On the bright side there are many open source llms, and it seems like there's more everyday.
