What would an app built on Grok Build 0.1 cost?
With 10,000 requests a month of 1,500 input and 400 output tokens, Grok Build 0.1 would cost about $23.00 a month at list price, without cache or batch discounts.
What is the API id of Grok Build 0.1?
The id is x-ai/grok-build-0.1. It is the name passed in the model parameter of the API (or on OpenRouter).
Where do the prices come from and how often are they updated?
From the public catalogs of OpenRouter, models.dev and LiteLLM, which publish each provider's list prices. They sync once a day and the last update date is shown above the comparison.
What does price per million tokens mean?
It is what the provider charges per million tokens you send (input) or the model generates (output). A token is roughly 4 characters. Output almost always costs more than input.
Sources: OpenRouter, models.dev and LiteLLM. Prices in USD per million tokens, list price, no volume discounts. Prompt tokens are an estimate; each provider's tokenizer may differ.
