What Gemma 4 Predicts When Watching Videos

matthen2 · x · 2026-07-19

The author asks: What exactly is a multimodal LLM "thinking" about when watching a video? The post mentions that Gemma 4 12B directly reads raw image patches and processes them like tokens. Although it hasn't been trained to make predictions on these "patch tokens," the video demonstrates what happens if you forcibly sample from its next-token head to see the predicted next step. This post is more of an exploration of the internal representations and prediction mechanisms of multimodal models rather than a standard product introduction.
