Okay but does any one actually _want_ a reasoning model at such low tok/sec speeds?!

You can have questions that are not urgent. It's like Cursor, I'm fine with the slow version until a certain point, I launch the request then I alt-tab to something else.

Yes it's slower, but well, for free (or cheap) it is acceptable.

Does adding memory help? There's a Rpi 5 with 16GB RAM recently available.

Memory capacity in itself doesn't help so long as the model+context fits in memory (and and 8B parameter Q4 model should fit in a single 8 GB Pi).

Is there a back-of-the-napkin way to calculate how much memory a given model will take? Or what parameter/quantization model will fit in a given memory size?

Can’t you run larger models easily on MacBook Pro laptops with the bigger memory options? I think I read that people are getting 100 tokens a second on 70B models.

haven’t measured but the 70b runs fine on an m1 macbook pro with 64gb of ram, although you can’t do much until it has finished

Only interactive uses cases need high tps, if you just want a process running somewhere ingesting and synthesizing data it’s fine. It’s done when it’s done.

Earlier quoted context omitted.

q4=4bits per weight

So Q4 8B would be ~4GB.

Lots of use cases don’t require low latency. Background work for agents. CI jobs. Other stuff I haven’t thought of.

If my "automated" CI job takes more than 5 minutes, I'll do it myself..
