Standardize Google Gemini API direct-model integration for chat, vision, Nano Banana image generation and editing, thinking levels, structured outputs, streaming, and function calling. Use when Codex needs to choose a Gemini model, wire generateContent or streamGenerateContent flows, expose thinking controls, JSON schema output, tool/function calling, image input, image generation, connection profiles, model selectors, or shared progress and error states. Do not use for Vertex AI, non-Gemini Google Cloud APIs, non-Gemini providers, Agent/App orchestration, or prompt-only work with no integration change.
