Take: The introductory price is the real news: for seven weeks a frontier model costs half its list price, so this is the cheapest window to run it against our own evals. I’d put Argon through the scoring prompts behind the AI interview product now, but write the comparison at the $4/$20 list price, because that is what production will pay after November 30.Gemini 4 Argon is generally available in GitHub Copilot, billed at provider list price and on by default for Business and Enterprise unless admins turn it offhttps://www.darius.wiki/en/daily/2026-10-14/copilot-gemini-4-argon/https://www.darius.wiki/en/daily/2026-10-14/copilot-gemini-4-argon/Wed, 14 Oct 2026 00:00:00 GMTToolsCopilot added Argon the same day Google launched it, across the CLI, the coding agent and every major IDE. Take: “On by default, billed at list price” is the line team leads should read. If you run Copilot Business, decide this week whether Argon goes on the allow list, and set a budget before people find it in the model picker. Pair it with the 10-10 change that lets code review be billed to the organization: model choice is now a cost line, not a preference.
