Comparison notes
Use these notes to interpret price differences without treating price as the only decision factor.
How is this provider comparison calculated?
The summary uses central model data for each provider, including available input prices, output prices, cached pricing, and model counts.
Should I choose based only on price?
No. Price matters, but quality, latency, context needs, reliability, and product fit should be tested before choosing.
Why run the calculator after comparing providers?
Provider tables show unit prices, while the calculator shows what those prices mean for your actual request and token volume.
