1. Choose the reason to switch
The right alternative differs if the constraint is price, queue time, audio, resolution or endpoint availability. Rank only the factors that can block delivery.
CORE FORMULAEffective cost = attempt cost ÷ acceptance rate
2. Run matched tests
Use the same aspect ratio, duration, reference asset and acceptance rubric. Otherwise the comparison measures configuration differences instead of models.
3. Keep a fallback endpoint
Production teams benefit from a second acceptable model even when it is not the cheapest. Availability can matter more than a small rate difference.

Frequently asked questions
What is the cheapest alternative?
It depends on the exact configuration and acceptance rate; use the live price index.
Can two models share the same prompt?
Yes for baseline testing, but final prompts usually need model-specific tuning.
