Are you referring to PALM-E? It didn't have any positive transfer for NLP tasks, in fact the unfrozen model performed slightly worse after the finetune. That being said, PALM-E wasn't really a multimodal model from the start, it's still basically just a text model with a visual one glued on top. Whether a truly multimodal model will be better at reasoning and data efficiency is still an open question though.
