Then they have a price table that is the official public API prices for the models, but converted to their AI credits.
Currently, I'm averaging 15 credits (0.15 $) per request for some QnA questions with claude sonnet 4.6. It should be similar with gpt 5.4 (same output token price, similar input token price).
I think with the current pricing you can do light work with normal models (10-20 code completions/day), but vibe coding, heavy usage or using bigger models is not viable anymore.
It's hard to measure since I did not average my token expenditure per day.
Unfortunately, nobody saved it on the wayback machine (I just did with today's page), but you can search "github copilot pricing multiplier" and still see on google images the cost increase x6 or x9 on some models.
I am on an Enterprise plan so it's different for me: I pay the subscription and I get credits, but the token pricing is essentially the same as the public API pricing.
I understand they needed to change it, but I don't like how they try to erase the old prices from the record.
