Choosing the right chat model

The right model balances task fit, output quality, latency, and price.

Selection signals

Match the model to the input and output you actually need.
Compare models that use the same pricing unit.
A small test reveals quality and latency differences that a catalog cannot.

FAQ

What makes a good chat model?

A strong fit matches the task, quality bar, latency target, and budget. A small evaluation set makes quality and reliability differences easier to see.

Can I switch models later?

Yes. Keep the public model ID and request format explicit, and compare alternatives on the same tasks.
