Advantages
- The provider's current API rates are linked; input and output prices are shown separately.

Disadvantages
- Caching, long context, tools, region, and service tier can change the final bill.
- A price comparison does not measure model quality for your task.
Example workload cost
For 100,000 input tokens and 25,000 output tokens, the standard-rate estimate is $0.0225: 0.1 × $0.1 input + 0.025 × $0.5 output per million tokens.
This is an estimate from the listed rate, not a vendor quote. Actual charges can vary with model options, discounts, minimums, retries, and plan terms.
Standard short-context price. Long-context, cached, batch/flex, regional, and tool rates differ.
