Researchers have demonstrated that frozen weights from the Gemma 4 31B text-pretrained model can be effectively reused across different modalities, including robotics and associative recall tasks. By employing a thin, trainable interface, these unmodified weights achieved state-of-the-art results on a robotic manipulation benchmark and matched Decision Transformer performance in reinforcement learning with significantly fewer trainable parameters. The study also identified specific transformer heads that are crucial for both text-based tasks and cross-modal applications, suggesting a deeper computational reuse mechanism within the model. AI
