Comparison notes
Use these notes to interpret price differences without treating price as the only decision factor.
What is the fastest way to compare these models?
Use the pricing table for unit costs, then run the calculator with your own request and token assumptions.
Which workload should I test first?
Start with your highest-volume workflow because small per-request differences matter most there.
Can model capability change the cost decision?
Yes. A cheaper model can cost more overall if it needs longer prompts, retries, or fallback calls.
