// how this ranking works
Every active Grok model ranked by blended price per million tokens. Only active models with a published price and context window are included. Prices are base-tier list prices in USD per million tokens; the blended price weights input and output 3:1, a typical mix for chat and RAG workloads. The data comes from models.dev and is refreshed every day, so this ranking changes as soon as a provider changes its prices.
