Questions to test
  • Does its current API support the formats, controls, and rights required by your frozen brief?
  • What prompt adherence, correction count, render time, and observed cost result from repeated runs?
  • Can a system scheduled for removal satisfy the required operating lifetime?
  • What migration path would be required before the documented removal date?
Pricing questionWhat do the current official plan, usage, and overage terms cost at your expected volume?What do the current official plan, usage, and overage terms cost at your expected volume?
Decision questionDoes Kling API produce the accepted output with fewer corrections, lower observed cost, or a better control fit on your frozen task?Does Sora 2 API produce the accepted output with fewer corrections, lower observed cost, or a better control fit on your frozen task?

Reproducible comparison rubric

Freeze one task, its inputs, acceptance criteria, account state, model settings, and evaluator before the first run. Use the same number of trials for both products.

  1. Record whether the output meets the acceptance criteria.
  2. Count reviewer corrections and recovery attempts.
  3. Record elapsed time to an accepted output.
  4. Record observed usage and billed cost from the test account.
  5. Publish raw results, settings, evaluator identity, and limitations.

Declare a winner only when the run and a predeclared decision rule are published. A tie or a split decision by task is valid.
