Introduction to Gemini 3

Why it matters

Model selection is an architecture decision only when you understand the behaviours and controls available to the application that calls the model.

What to practise

Run text and multimodal prompts, vary generation controls, request structured output, and observe tool calling and code execution through the model API.

How it fits

Pair observations with subsection 3.1’s model-sourcing and execution-model Bites. Separate a model capability from the orchestration and governance an agent runtime adds around it.
