Token cost calculator
LLM token cost calculator
Type in your monthly tokens, or requests and their average size, then tick the models to compare. You get each model's monthly cost at list price, cheapest first. It runs in your browser with no sign up, and the link in your address bar keeps your numbers so you can share them.

Just want a quick monthly estimate that stays on this screen? The AI API cost calculator does that, and nothing you type goes into a link.
Send each request to the model it needs.
Connect your own Anthropic, OpenAI, and xAI API keys, and FUSR.ai picks a model per request by rules you can read. Run npx fusrai setup in your terminal, or start in the browser.
You bring your own API keys. Chat plans like Claude Pro or ChatGPT Plus are separate and FUSR.ai does not use them.
