Claude API pricing
Part of Claude
The Claude API is how developers pay for Anthropic's models: per million tokens, with input and output priced separately and every model tier a fixed step apart. Since Opus 4.5 in late 2025 the top tier has dropped from $15 to $5 per million input tokens while a new tier above it, Fable 5.1, took the $10 slot.
