Start with the task
Everyday drafting and straightforward questions may suit a faster model. Complex analysis or reasoning may benefit from a more capable option.
Read the cost band
A single $ indicates a lower relative cost band, $$ a middle band and $$$ a higher band. They are approximate comparisons, not exact prices or subscription charges.
Check current availability
Model providers and availability can change. The live selector is the source of truth for choices available now.
Use reasoning where it helps
Reasoning is available only for supported models. It can add effort to a task, but does not guarantee accuracy.
Verify regardless of model
Check calculations, citations, sensitive conclusions and external actions. Higher capability still requires your judgment.
