Open calculatorA note on accuracy
Pricing comes from OpenAI, Anthropic, and Google's published rates and is updated when they change. Numbers here are standard-tier estimates — volume discounts, prompt caching, and batch processing will all push your real bill lower. They tell you totals; for spend broken out by customer or feature, that's PerUnit. For longer reads, see the blog.
