Google has released Gemini 4 Hydrogen to replace Gemini 3.8 Flash. Its overall score is slightly above Argon, it runs about 2.5 times faster, and it has a free tier in AI Studio and the Gemini API, with paid use at $1.50 per million input tokens. We cover the benchmarks, pricing, where to use it, how to migrate from older models, and a prompt you can give your AI agent to switch models for you.

Google's Gemini Decisions API and the new Gemini Decision 1 model handle closed questions: yes or no, pick one, or score on a scale. Up to 1000 questions per request, about 0.2 seconds per response, and free output. Useful for choosing tools for an AI agent, routing requests, and running safety checks. Includes a prompt you can hand to your AI agent to try it.

Gemini 4 Carbon is now open to everyone through the paid API and Google AI Ultra. It's built for long-running agent work and cybersecurity. Here's how it splits work with Argon, when the price doubles, and what Antigravity's /swarm does.

Google's A2UI 1.0 lets an agent say what belongs on screen while your app paints it with its own native parts: forms, charts and confirmation cards. Jira and Alation already use it, and it runs in Claude and Gemini through MCP Apps. Includes a prompt that walks your AI agent through the quickstart.

A breakdown by use of what Google AI Ultra bundles: Colab compute, monthly Cloud credits, Flow image and video quotas, Antigravity coding quotas, 30TB of storage and various memberships, plus how the quotas are calculated separately.
