TL;DR
Within two weeks in June 2026, GitHub Copilot moved its monthly plans to metered AI credits and Anthropic pulled programmatic Claude usage out of the flat subscription into a separate credit pool billed at API rates. If you are building an AI SaaS, the question is no longer whether to meter usage, but which billing model fits your cost structure: credit-based or classic subscription.
The problem
Most AI products still run on the classic billing model: pay a fixed monthly fee, use the product as much as you want. AI coding tools sold that promise too, and it worked while most users were light users. Agents broke it.
On June 1, 2026, GitHub Copilot switched its monthly plans to usage-based billing. Premium Request Units were replaced by "GitHub AI Credits" tied to actual token consumption at API list prices; annual plans keep the old model until they renew. The plan base prices stayed the same (Pro at 10 dollars, Pro+ at 39, Business at 19 per seat), but token-heavy work got more expensive. Developers who ran their April usage through the new billing preview reported projections jumping from roughly 29 dollars to 750, in one case from 50 to around 3,000. By June 2, the community thread had collected 435 comments and over 900 downvotes against just 22 upvotes.
