This. Price is set by value delivered and what the market will pay for whatever capacity they have; it’s not a cost + X% market.

I'm more curious about the input/output token discrepancy

Their pricing suggests that either output tokens are more expensive for some technical reason, or they're trying to encourage a specific type of usage pattern, etc.

Or that market research showed a higher price for input tokens would drive customers away, while a lower price for output tokens would leave money on the table.
