Common workload examples

Input only

1M input tokens

$1.00 under the standard.short_context profile, excluding output and other charges.

Output only

1M output tokens

$6.00 under the standard.short_context profile, excluding input and other charges.

Default workload

10,000 monthly requests

At 1,000 input and 500 output tokens per request: $40.00 under standard / short context.

Cache scenario

50% cached input

The same default workload with 50% cached input is estimated at $35.50. Cache savings apply only to the tracked cached-input rate.

Verification

Sources and methodology

Pricing and limits are source-tracked and may change. Verify current values with the provider before making production purchasing decisions.

Calculator profile rule: standard.short_context is the verified default. Requests with more than 272,000 input tokens use the higher long-context rate for the full request.
