Model multipliers were derived from an internal report rather than the authoritative public pricing page. This replaces them with values from https://docs.github.com/en/copilot/reference/copilot-billing/models-and-pricing using a direct mapping: $1 USD per 1M input tokens = 1x multiplier.

Changes

  • pkg/cli/data/model_multipliers.json + actions/setup/js/model_multipliers.json — Updated multipliers for all models listed on the pricing page (44 entries across 15 canonical models and their date/variant aliases). Models absent from the pricing page retain existing values.
  • description field — Updated to cite the new source of truth and conversion rule.
  • docs/src/content/docs/reference/model-tables.md — Regenerated.
  • pkg/cli/effective_tokens_test.go — Updated inventory test expectations to the new values.
  • .changeset/ — New patch changeset added.
