Gemini models and the Gemini API, Gemma open models, and Google’s developer tools for agents. Every brief item about Google, newest first, each with its primary source.
Where it stands
Google has shipped on two tracks this month. On the open side it released EmbeddingGemma 2 on October 6 under Apache 2.0, then open-sourced the AQuA production-agent auditor and the ML Drift on-device GPU inference engine on October 8. On October 13 it released Gemini 4 Argon, its new frontier model, at an introductory $2/$10 per million tokens until November 30 and $4/$20 after, and GitHub made it generally available in Copilot the same day.
The trend is that Google is competing on price and distribution at once: a frontier model launched at half its list price, available on day one in Copilot as well as its own Antigravity, AI Studio and Gemini app, with open models and tooling keeping developers in its ecosystem below the frontier.
What to watch next: whether the introductory price is extended past November 30, how Argon’s 1M unified token limit and continuation protocol behave in long agent runs, and what Argon costs per finished task compared with other frontier models.
My advice: use the next seven weeks to run Argon on your own evals while it is cheap, but make the decision at list price; and if you use Gemma or EmbeddingGemma locally, look at the vLLM changes Google upstreamed, since they are free speed.

- Model release blog.google ↗Google releases Gemini 4 Argon at an introductory $2/$10 per million tokens until November 30, then $4/$20, with a 1M unified input-output limit
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.
From the Oct 14 brief · item 01 → - Tools github.blog ↗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 off
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.
