Seedance 2.5 is priced 53% above 2.0 per token, and its 480p frame shrank

Short summary

Seedance 2.5's per-token price is 53% higher than 2.0, and its 480p frame is 4.5% smaller (854×480 vs ~864×496), creating a hidden discrepancy between token-rate increases and per-second cost increases. The analysis reverse-engineers ByteDance's token metering formula to show that 4K is cheapest per token but most expensive per output, and that reference-video inputs are billed at the same rate as generated frames. Includes a cost calculator function for accurate billing.

• •Seedance 2.5 costs 53% more per token than 2.0 but only 46% more per second at 480p due to a smaller frame size
• •4K tier is cheapest per token but 19× more pixels makes it the most expensive output — rate-column comparisons are misleading
• •Reference video inputs are billed at full rate, so a 30-second reference on a 5-second output costs 3.9× more
