Essay = a 1,000-word essay; Chat = a 100-message conversation; PDF = summarizing a 50-page PDF. *A rule of thumb: one page is about 500 words, and a model "reads" about 0.75 words per token. Smartness is our 1 to 5 banding of the Artificial Analysis Intelligence Index (how); "Not rated yet" means no score is available. Costs are computed from list prices using the assumptions on How we work.

Smarter does not always mean pricier

Among the models rated 5 of 5, a 100-message chat costs from $2.62 to $13.12; for 4 of 5 it runs from $0.13 to $2.54. A higher rating does not always cost more.
