A Claude.ai subscription is a separate flat fee. These are the API prices, which is what you pay if you're calling Claude from your own code or from Claude Code.

Claude Opus 4.1 is marked deprecated in Anthropic's own docs, so they're left out of the table above. The deprecation list has the dates.
