Profitable without Capex, i.e. gross margin. Inference is included in COGS. Capex (training) is not. That's reasonable.
This also includes revenue sharing with distribution partners, which should probably be in COGS.
Isn't training necessary for the end-product? How is it not a cost to generate the output if you can't generate the output without having done the training? Seems more like saying that a car is profitable product when you don't have to account for the steel that its made from. Seems completely disingenuous.
Is it really capex though? New models are being constantly trained, released at least quarterly, while old ones become obsolete. Training costs vary, but never disappear.
