Let's go Bananas with GenMedia — Guillaume Vernade, Google DeepMind

Guillaume Vernade from Google DeepMind demonstrates the full GenMedia stack—Nano Banana for images, Veo for video, Lyria for music, and TTS—by illustrating an open-source book live. The core insight is that Gemini acts as the prompt engineer for every other model, and this works partly because the gen media models were trained on prompts written by Gemini. He shows how to generate character portraits, chapter scenes, animated video clips using images as first frames, and distinct music per chapter, with Lyria Realtime allowing continuous music that responds to new prompts like a DJ. A new interactions API caches context server-side to make chained multi-turn calls cheaper. For TTS, he uses a trick: assigning different speaking styles (e.g., long poetic pauses vs. breathless stutter) to the same two voices to create four distinct-sounding characters.
