Lead Green is a public index of the GPU energy it takes to serve a million output tokens (watt-hours per million output tokens), by model, GPU and configuration, with grid carbon intensity to price it anywhere, published as open data with a JSON API and an MCP server under CC BY 4.0. Every figure comes from a named public source with a retrieval date; it is a Katonic project, run and paid for by Katonic, and takes no money from hardware, cloud or model vendors.
