Methodology and limits
Prices are list prices in USD per 1M tokens from the provider's pricing page; dates and named replacements come from the provider's deprecation page, quoted above with the date we last checked. The replacement is the provider's named replacement, not our recommendation — quality and behavior can differ. Discounts, committed-use or enterprise agreements, batch and regional pricing, and Azure OpenAI and Amazon Bedrock prices are not included. Dates marked "at least through" or "not before" are shown but never applied.Full methodology →
