AI Agent Cost & Tools Hub

Not sure what your AI agent will cost? AI Agent Cost & Tools Hub is a free, beginner-friendly calculator. Pick a preset like "support bot" or "coding agent", enter how many tasks it runs a day, and see the monthly bill side by side for 79 models from OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral and more. Agents make several model calls per task, so costs add up faster than with a chat. The calculator counts steps, input and output tokens and prompt caching, and every price is checked daily against official provider pages (the "last verified" date is on every page). It also has plain-English guides (cost per month, prompt caching, cutting token costs, cheapest LLMs for agents), model-vs-model comparisons, a directory of agent tools and a free weekly newsletter. Share links and CSV export included, no account needed. It's a small independent project; AI helped write the text and build the calculator, and the numbers come only from the price data.
