How much does Claude Sonnet 4.6 cost per API call?

Claude Sonnet 4.6 costs $3.00 per million input tokens and $15.00 per million output tokens. Claude Haiku 4.5 is much cheaper at $0.25 input / $1.25 output per million tokens, while Claude Opus 4.6 is $15 input / $75 output.

Does Anthropic offer prompt caching?

Yes. Anthropic offers prompt caching which lets you cache up to 200K tokens of context. Cache writes cost 1.25× the normal input rate, but cache reads are 90% cheaper — making it valuable for large, repeated system prompts.

How does Claude pricing compare to GPT-4o?

Claude Sonnet 4.6 ($3 input / $15 output) is slightly more expensive for input but cheaper per output token compared to GPT-4o ($2.50 input / $10 output). For high-output tasks, GPT-4o may be more cost-effective.
