Based on my experience with Grok, GPT, Gemini, Qwen, Minimax, Claude, Deepseek... For something I'd keep on me, I'd want a locally hosted, probably whichever FOSS one I like at the time. At the moment? Probably Minimax, Kimi, or Qwen. Though now that I think about it Bitnet might be the better choice for the hardware constraints.
