Lol:

The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog.

However, it delivers a jaw-dropping 750 kilowatts of power, which is the equivalent of 1,005 horsepower.

I feel like we’d need peak horsepower output of a small dog to truly understand this.

A dog’s power output comes from its muscle mass, which for a healthy dog is about 45% of its total body weight. This gives our 28-pound dog roughly 5.7 kg of muscle.

Studies of animal muscle show that the peak power output of vertebrate muscle tissue during a short, explosive burst (like a jump or the start of a sprint) is around 100 to 200 watts per kilogram of muscle.

Now we can estimate the dog’s peak power:

  • Low estimate: 5.7 kg of muscle x 100 W/kg = 570 watts
  • High estimate: 5.7 kg of muscle x 200 W/kg = 1140 watts

Converting these figures to horsepower (1 horsepower = 746 watts):

  • Low estimate: 570 W / 746 ≈ 0.76 horsepower
  • High estimate: 1140 W / 746 ≈ 1.5 horsepower

So, a small 28-pound dog might be able to generate a peak power of around 0.75 to 1.5 horsepower for a very brief moment.

So this YASA motor is somewhere between 670 and 1,340 times more powerful than the dog it’s being compared to in weight. That’s some jaw-dropping power output.

Stop burning the planet down to generate social media comments about shit you don’t understand

How do you know they’re not running a local model? Ultimately the problem with LLM accusations is that short of a confession or doing some hardcore surveillance of the other person you can’t prove it

Ultimately the problem with LLM accusations is that short of a confession or doing some hardcore surveillance of the other person you can’t prove it

Human variation.

Ironically you would have to take the others person word on it, luckily you just said you were comfortable doing so.

Some people are statistically insignificant, and to them lots of stuff is incredibly obvious and they’re constantly frustrated others can’t see it. They might even sink sizeable free time into explaining random shit, just to practice not losing their temper when people can’t see the obvious.

So you might not be able to tell that was AI from a glance, but humans are pattern recognition machines and we’re not all equally good at it.

So believe a “llm accusation” or not, but some people absolutely can pick out a chatbot response, especially when taking the two seconds to glance at typical comments from a user profile.

Jump from 1-2 sentence comments to a stereotypical AI response…

Well, again, not everyone is as good at picking out patterns quickly.

To some what took me literally under 10 seconds and two clicks counts as “hardcore surveillance” because it would take them a long time to figure it out.

Don’t assume everyone else is exactly like you.
