Summary of Changes

Hello @Giom-V, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request systematically updates the model references within numerous example and quickstart Jupyter notebooks. The primary goal is to replace older, deprecated, or less performant generative AI models with their newer, recommended counterparts, such as upgrading to gemini-2.5-flash, gemini-embedding-001, and imagen-4.0-generate-001. This ensures that users are always working with the most current and capable versions of the models, improving the relevance and accuracy of the provided examples.

Highlights

Model Upgrades: Replaced deprecated embedding models like text-embedding-004 with the newer gemini-embedding-001 across multiple example and quickstart notebooks, ensuring consistency with current recommendations.
Generative Model Updates: Upgraded various instances of gemini-2.0-flash to gemini-2.5-flash in several notebooks, including those demonstrating ReAct prompting, PDF structured outputs, and story writing, to leverage improved capabilities.
Image Generation Model Migration: Migrated references from imagen-3.0-generate-002 to imagen-4.0-generate-001 and gemini-2.0-flash-preview-image-generation to gemini-2.5-flash-image in relevant examples and quickstarts, reflecting the latest image generation models.
Live API Model Refresh: Updated Live API models from older versions such as gemini-2.0-flash-live-001 and gemini-live-2.5-flash-preview to the more recent gemini-2.5-flash-native-audio-preview-12-2025.
Model List Synchronization: Ensured the quickstarts/Models.ipynb notebook accurately reflects the latest available model names, including new gemini-3 preview models and veo-3.1 models, providing an up-to-date overview of the model landscape.

Code Review

This pull request aims to update deprecated model names across various notebooks. While most of the updates are correct, there are several instances where the list of models in @param decorators now contains duplicate entries. Additionally, in a few markdown cells, the description of a model is now inconsistent with the updated model ID. I've left specific comments on these issues.
