Calculators for what AI work costs

Each tool uses the prices and limits on this site, says which numbers are measured and which are assumptions, and gives a result you can copy as a Markdown table with its source.

• Model picker Six common tasks, your volume and data rules: the models that meet them, cost a month, a cheap-first combination and what is still unknown.
• Task cost calculator Cost of one task, then per hour, week and month: growing input, cache, visible output, hidden reasoning.
• Rate limit planner A batch job and a deadline: requests and tokens per minute, the published tier that makes it, batch and rented GPUs.
• Subscription vs API Seats, active share, tasks per day and the plan’s limit window against the same work through the API.
• VRAM & GPU cost Does the model fit the card, and what a million tokens costs on your own GPU with idle time.
• Token counter Tokens for text, images and PDF pages with each provider’s counting rules.
• Invoice auditor Reads your usage export in the browser: what you paid, cheaper models of the same class, and where the money goes.
• Prompt cache auditor Paste an API request to see what breaks the provider’s prompt cache and what a fixed request saves.
