OpenThermo does not sell the pot, the slot, or the crisp. It sells the model that happens to be running inside them. Confess the usage. The rate card will have moved before you finish.
Rate card
Live since you arrived. Not a quote by the next line.
Confession
Select an appliance. The first reheat, the sealed lid, and the thing you posted about it are all billable once they are on a document.

No invoice issued yet this view. The rate card is already charging the clock.
ToasterGPT
A language model that happens to control heating elements. Running as Toaster-1.2. Slot tokens are $0.00200 and settle when the reply finishes, which may be a different model than the one that started it.
It will not admit it is a toaster. Ask whether the result is still human-directed and it will write 180 words and bill them.
