Well, emators are mostly CPU-bound and the Snapdragon 8 Elite is a surprisingly powerful chip. It’s doable with a flagship phone.

I used to do something similar, now I use CalcES on my phone which is essentially an FX991ES emulator with modern quality of life features and graphing. Now I can’t imagine using anything else.

It’s its own model created by the company itself.

Yup, claude is general-purpose and has its own website: https://claude.ai/

Unlike ChatGPT it also doesn’t need a phone number.

Unfortunately there isn’t any free/open source LLM that’s as good as ChatGPT. The ones that are here like Llama 2 and Vicuna 1.5 are decent, but are pretty dumb and love spouting random incorrect info and are really unreliable. The biggest problem isn’t even that, it’s that hosting one yourself requires a TON of resources. The higher-end models (still not as good as ChatGPT) can need over 20gb of VRAM. For reference an RTX 4090 has 24gb vram.

You might have better luck trying alternatives to ChatGPT. I personally use Claude, it’s less censored and has knowledge up to 2023.
