I feel this is going into increasingly-unlikely mixes of constraints and needs in order to try to keep a "wouldn't it be cool if" hypothetical-tool dream alive. [0] But OK, let's assume that: The power is out, but you have a generator with so much fuel you can run a desktop just fine; Your neighborhood will somehow make a mesh network; Your neighbors need some already stored information and the best solution for that…
Option 1 sounds better: I’m only out the cost of the drive, which is like $40 and doesn’t require anybody on the other side cooperate with me. - - - More broadly… You call it unlikely mixes, but we see it all the time: - people already have a computer for gaming or work - people (ie, “preppers” like we’re discussing) buy a generator for emergencies - local emergency response sets up mesh networking during disasters,…
At current prices you are also out about $4k for a Spark to actually run the inference on, if you want a full LLM in a low-power package.
In general, I'm not sure why one would want to pin your survival to an expensive, hallucination-prone data source, when an offline copy of wikipedia with a little vector search attached to a Raspberry Pi can fulfil the same role...
