How to read this comparison
A lower price per token does not settle which model is cheaper for you. The two models can differ in how the bill splits between input and output: one may have cheaper input and dearer output than the other. Which side wins depends on how long your prompts are compared with the answers you ask for, so set the workload above to your own traffic before reading the last row.
If your requests repeat a long prefix, such as a system prompt or a document, raise “From cache”. The share you set is billed at each model’s cache-read price when one is published, which can change the result when only one of the two offers it. Reasoning models bill hidden thinking as output: for those, raise the output tokens to what your requests really consume.
Price is one axis. Context window, maximum output and accepted inputs are listed because they decide whether a model can do the job at all; the Intelligence Index, where shown, is a third-party score from Artificial Analysis and not a judgement by this site.
