Summary of Changes

Hello @jdomingr, 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 significantly expands the Generative AI SDK's live samples, providing developers with practical examples for integrating advanced AI capabilities. The new samples cover a range of interactive scenarios, from real-time audio conversations and text-to-speech generation to complex function calling, grounding with RAG engines, and structured data extraction. These additions aim to enhance understanding and ease of use for various live AI applications.

Highlights

• New Live Samples Added: Introduced six new live samples demonstrating various functionalities of the Generative AI SDK.
• Audio Interaction: Added samples for live audio response from text input, and live conversation with audio input and audio output.
• Function Calling: Included a new sample showcasing live function calling with text input.
• Grounding with RAG Engine: Provided a sample demonstrating live grounding using Vertex AI RAG Engine with text input.
• Structured Output: Added a sample for live structured output using the OpenAI client.
• Text Response from Audio: Implemented a sample to get live text responses from audio input.

Code Review

This pull request introduces several new live samples for the GenAI SDK, covering audio responses, conversation, function calling, grounding, structured output, and text responses from audio. The changes include adding a new dependency for OpenAI client and new Java files for each sample. Overall, the new samples demonstrate various capabilities of the Live API effectively. However, there are several instances of hardcoded values and placeholders that should be made configurable for better reusability and clarity.

[gemini-code-assist]

The MIME type and audio rate are hardcoded. These values might vary depending on the audio source. It would be better to derive them from the audioBytes or make them configurable.

            .audio(Blob.builder().data(audioBytes).mimeType("audio/pcm;rate=16000").build()) // Consider making mimeType and rate dynamic
