# Units ### What is a Unit? On The Grid a Unit is the atomic building block of capacity. One Unit equals 1 million tokens of inference output, covering both input and output tokens. Units are what you buy on the order book, what moves between your Trading and Consumption accounts, and what gets drawn down when your application makes API calls. Each Unit is tied to a specific Instrument (like Text Max, Text Prime, or Text Standard), which defines the minimum intelligence, latency, and throughput you receive. * One Unit represents **1 million tokens** of inference capacity. Input and output tokens are counted as the same. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://thegrid.ai/docs/introduction/core-concepts/units.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
