I wrote a program to classify thousands of images but that was using a model running on my gaming PC. Took about 3 days to classify them all. Only cost me the power right?
Power, gaming rig, internet, somewhere to store the rig, probably pay property taxes too.
You can draw the line wherever you want. :) Personally, I wish I'd built a new gaming rig a year ago so I could mess with local models and pay all these same costs.
