FAQ
LLM Price Compare FAQ
How should I compare model prices fairly?
Use a blended cost that weights input and output by your real ratio, and normalize currencies. Cheap output but expensive input can flip the ranking for chat-heavy traffic.
Are these prices live?
Prices come from the NextModel catalog with a source label per model. Always confirm against the provider before committing high-volume traffic.
