Each model gets the same prompt. These runs show how their creative choices differ.

Dates use London time. Elapsed time covers the initial creation run, including checks and preview work. Token counts come from local logs and cover the main agent only, including repeated cached input and output. They exclude subagents and later changes.

USD estimates apply standard API token rates checked on 29 Sep 2026, including cache reads and writes. They are not billed amounts and exclude subscriptions, separate tool fees, and taxes.
