This sample is part of the AI Sample Catalog. To build and run this sample, you should clone the entire repository.

This sample demonstrates how to use the Firebase Hybrid SDK, utilizing both on-device (Gemini Nano via ML Kit Prompt API) and cloud-based models via the Firebase AI Logic SDK.

The sample lets users generate generic user reviews for a hotel based on a few selected topics.

Here is how the model is instantiated to leverage hybrid inference:

val model = Firebase.ai(backend = GenerativeBackend.googleAI())
                .generativeModel(
                    "gemini-2.5-flash-lite",
                    onDeviceConfig = OnDeviceConfig(mode = InferenceMode.PREFER_ON_DEVICE)
                )

val response = model.generateContent(prompt)
