Frequently Asked Questions
What is a prompt cost calculator?
A prompt cost calculator estimates the API cost of running a prompt on AI models such as GPT, Claude or Gemini based on token usage.
How is prompt cost calculated?
Prompt cost is calculated using the number of input tokens and output tokens multiplied by the price per 1,000 tokens for each model.
Do different AI models have different prices?
Yes. Models like GPT-4o, Claude 3 and Gemini have different pricing for input tokens and output tokens.
Why should developers calculate prompt cost?
Calculating prompt cost helps developers control API spending and optimize prompts before running them in production applications.
Does this calculator support Gemini models?
Yes. This tool supports OpenAI GPT models, Anthropic Claude models and Google Gemini models.
