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.
