What developers pay per million tokens to call each model through its API (not the ChatGPT, Claude or Gemini app subscriptions). Read every week straight from each provider's own pricing page, checked against that page before it's shown, and compared with OpenRouter as a second opinion.
Prices are the standard pay-as-you-go tier at the base context length. Batch, cached-input and long-context rates are on each provider's page.
