Explicit assumptions

Common workload examples

Input only

1M input tokens

$10.00 under the standard.short_context profile, excluding output and other charges.

Output only

1M output tokens

$50.00 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: $350.00 under standard / short context.

Cache scenario

50% cached input

The same default workload with 50% cached input is estimated at $305.00. Cache savings apply only to the tracked cached-input rate.
