How much does it cost to summarise a long document?

Scenario: A 50,000-token document in, a 1,000-token summary out.

Input dominates here, so the cheaper input price of Flash matters most.

How it's calculated: input tokens × input price + output tokens × output price, per 1M tokens, rounded up per call to the next millionth of a dollar. Prices: Flash $1.60 / $3.40, Max $1.80 / $3.80, Heavy $2.00 / $4.40; prompts over 262K tokens bill their whole input at 1.5×. These are estimates from the list prices; Max and Heavy usually write more output tokens than Flash for the same task because they reason first.
