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.

How we chose: Free to download does not mean easy to run: the biggest ones need a room full of computers.
