Home AI Fans Argue: How Slow Is Too Slow Before You Give Up?

A popular question is bouncing around the community of people who run AI chatbots on their own laptops and desktops: how slow is too slow? The number they argue about is 'tokens per second,' or TPS. A token is a chunk of a word — roughly three-quarters of one — so 30 TPS works out to about 22 words every second. That's several times faster than you can read. So why does anyone complain? Because when a model runs slower than that, watching it answer feels like watching someone peck at a keyboard.

Here's the real trade-off. Big, smart AI models need serious computing muscle. If you're running one on your own machine, it may only manage 10 or 20 TPS — noticeably sluggish, but the answers are better. Smaller models are quick and light, often hitting 100 to 150 TPS, but they stumble on harder questions. So the debate isn't really about speed. It's about whether you'd rather wait a bit for a smarter answer, or get a fast answer that's more likely to be wrong.

Why does this matter to you? Because running AI at home is quietly becoming an alternative to paying monthly subscriptions. If you own a decent gaming computer, you can already run a capable chatbot for free, with nothing sent to a company's servers. The catch is that you become your own tech support — juggling speed, quality, and memory settings yourself. Nobody hands you a dial labeled 'good enough.'

The thread has no resolution, and that's the honest takeaway. People's patience varies wildly depending on what they're doing. Drafting an email? Slow is fine. Chatting back and forth like a conversation? Speed matters a lot. If you're curious, most free tools let you try both and decide for yourself. Your own annoyance threshold is the only benchmark that counts.
