A visualization of the data from

as of July 9/2025, to compare usage (Tokens on the X axis) and cost (on the Y axis).
Claude Sonnet 4 and Gemini 2.5 Pro are the clear winners. DeepSeek V3 0324 is surprisingly positioned in that it has extremely low cost, but people are actually using it quite a lot. Claude Opus seems just too expensive for people to actually use.
