is there a website where i can compare openai, anthropic and gemini models on cost/token ?
You really need to look at the cost per task. artificialanalysis.ai has a good composite score, measures the cost of running all the benchmarks, and has 2d a intelligence vs. cost graph.
Tried a lot of them and settled on this one, they update instantly on model release and having all models on one page is the best UX.
