It's not about a secret super duper version, just specialisation. If military needs a product for location finding they can train that to a much better quality in a much smaller space than chatgpt, which needs to do just about anything. You can spend 100% energy on the task you want instead of memorising the bible.

Medical industry does it. Coding autocomplete solutions do it. Large deployments of support agents do it. Etc.

There's more than one dimension. Chatgpt is way worse at classifying my data than my custom 30k weight model. (And around infinity times more expensive) Which is more powerful? Yeah...
