For anyone reading that has never ran local llms, please understand that anything under 100 tok/sec is worthless. You are faster typing stuff into Gemini free version that you get with a google account and copy/pasting it in (and you can easily build browser automation with playwright or any other js runtime to have this available in a chat window)
I get 80 tok/s on the same model, and it's pretty usable. I'm not chatting with it; it's either given a bag of tokens to generate an answer or it's doing some agentic coding.
https://openrouter.ai/anthropic/claude-opus-5 is it worthless because its 65 tps?
re: gemini
https://openrouter.ai/google/gemini-3.7-flash worthless as well?
That being said, 14 tok/s is pretty slow.
In agentic scenarios, an LLM has to read far more tokens than it outputs. I think focusing only on the decode speed is somewhat misleading. 14 tok/sec for decode is actually okayish. 93 tok/sec prefill is what's abysmal, my RTX 5090 goes above 2000 tok/sec with 5 bit quants.
What? Below 100tk/s is worthless?
I agree that 14t/s is pretty tedious for interactive use, yes. But 50-60tk/s is faster than I can read. 100tk/s is outright fast. Don't forget there is a limit entering content into meatspace.
Also, Gemini may be free but what if I don't want to give all my data to Google? This is precisely why I have a lot of stuff locally.
And will it remain free? How are they going to make back all those trillions of investment?
But yeah I would kinda balk at 14tk/s too that's why I use old datacenter/workstation-class GPUs.
I mean, if you don't care about your inputs being trained on, you can just use one of the many free models on openrouter.
Quality of tokens matters almost as much.
30 is worth it on a meaningfully better model, though annoying. 50 is pretty much unnoticeable (good old 60 FPS). 80-100 is heaven (aka 120 FPS - once you get used to it, it does suck to go back).
I would still rather have 30 tokens per second of GLM 5.3 Flash than 100 tokens per second of Qwen 3.6 35B-A3B.
