Price calculation example

The basic text-token estimate separates input and output. For 1,000 input tokens and 500 output tokens:

Input: 1,000 ÷ 1,000,000 × $2.50 = $0.0025Output: 500 ÷ 1,000,000 × $10.00 = $0.005Estimated total: $0.0075 USD

Estimated cost; excludes taxes and unsupported billing components. Cached, batch, audio, image, and other special billing components are not included. Tokenizer estimates also make the final cost approximate.

Context and data limitations

The context figure is the upstream value captured in this snapshot, not a guarantee of availability, output length, rate limits, or behavior on every provider. This page does not infer model capabilities beyond the price, context, and tokenizer mapping shown above.
