Summary of Changes

Hello @cfloress, 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 introduces new Go samples for the Google Generative AI SDK, expanding its capabilities to include controlled content generation using schemas, enhanced safety settings for text output, and the ability to generate videos from both text and image inputs. These additions provide developers with practical examples for leveraging advanced GenAI features.

Highlights

• Controlled Generation Sample: Added a new Go sample demonstrating how to enforce a specific JSON schema for generated text, including support for nested objects and enumerated types.
• Safety Settings Sample: Introduced a new Go sample showcasing the application of safety settings to text generation requests, allowing users to configure thresholds for various harm categories.
• Video Generation Samples: Provided two new Go samples for video generation: one that generates video based on a text prompt and another that generates video from an input image, both with configurable aspect ratios and GCS output.

Code Review

This pull request adds several new Go samples for the GenAI SDK, covering controlled generation, safety settings, and video generation. The code is generally well-structured and the examples are clear.

I have a few suggestions to improve the code quality and fix a bug in the tests:

• In the safety sample, a prompt string contains unnecessary whitespace which should be removed for better readability.
• The two video generation samples share a significant amount of duplicate code. I recommend refactoring this into a common helper function to improve maintainability.
• The test for video generation uses a hardcoded placeholder for a GCS bucket name, which is a critical issue that will cause the tests to fail. This must be corrected.

Detailed feedback is provided in the comments on the respective files.
