Flat-rate AI subscriptions are giving way to usage- and outcome-based billing — and the timing is specific: GitHub, Anthropic, and OpenAI all made moves in spring 2026. This episode explains why the shift happened, why per-token prices falling and enterprise bills rising are both true at the same time, and what operators should be asking their vendors right now.

- GitHub Copilot moved to token-metered "AI Credits" on June 1, 2026 — 1 credit = $0.01, no rollover

- Anthropic blocked third-party agentic tools from Claude Pro and Max subscriptions in April 2026, pushing heavy users to pay-per-token API pricing

- OpenAI layered metered consumption on top of ChatGPT Enterprise seat fees the same month, adding per-user credit tracking and budget controls

- The three pricing models — flat-rate, usage-based, outcome-based — differ in who carries the variance when consumption spikes

- The cheaper-yet-costlier paradox is a Jevons-paradox dynamic: per-token prices fell over 90% since 2023 while token volume rose roughly 450% in a year

- Outcome-based pricing shifts risk furthest onto the vendor but introduces a measurement problem that has no clean industry solution yet
