GoKawiilArtificial Analysis publishes daily-updated chart ranking LLMs by price vs performance
Artificial Analysis maintains an Intelligence Index that plots large language models against their blended API cost per million tokens, using a 3:1 input-to-output ratio and a log-price scale. The tool highlights a 'value frontier' of models that aren't beaten on both price and intelligence by any other option, showing only top variants and hiding low scorers by default, with filters to expand the view.
