Sending prompts to the GPT API without knowing the token count is like shopping without checking prices — you might get a nasty surprise at checkout. GPT Calculator is a simple, practical tool that lets you calculate the token count and estimated cost of your prompt before you run it. Just select your model — GPT-4, GPT-3.5, GPT-3 Ada, or GPT-3 Davinci — paste in your text, and get instant results.
It's especially useful for developers and teams building on the API who need to budget for usage and optimize prompt length. Note that the calculator covers prompt token costs; output token costs will vary based on the model's responses. A small tool that saves big surprises on your API bill.
