Copilot moves to per‑token billing on June 1, replacing premium‑request pricing

- GitHub is moving Copilot from a premium request model to token-based usage billing on June 1 and is urging individual users to review estimated costs now. - The company published new model multipliers for annual plans that remain request-based, signalling legacy plans will be recalibrated rather than left unchanged. - The change effectively treats developer tooling as metered infrastructure and raises the need for spend controls in internal AI gateways.
