Pricing Details

Opus does not offer a completely free plan, but lighter models such as Haiku and Sonnet can be tried on a limited basis. Paid plans allow Opus to be used via API at a cost of $5 per million input tokens and $25 per million output tokens. Developer, Professional, and Enterprise plans include advanced features for coding, project management, agentic automation, and advanced workflows, with discounts when using batch processing or prompt caching to reduce cost for large jobs.
