PaLM-E

The PaLM-E project introduces an innovative Embodied Multimodal Language Model, which integrates real-world sensor data with linguistic models for advanced robotic tasks. PaLM-E, short for "Projection-based Language Model embodied," fuses textual inputs with continuous sensory information, such as visual and state estimation data, to create a comprehensive understanding and interaction in the physical world. Designed to aid in tasks like robotic manipulation planning, visual question answering, and captioning, PaLM-E showcases the potential of large, multimodal language models trained on varied tasks across domains. With its largest iteration, PaLM-E-562B, boasting 562 billion parameters, the model not only excels in robotic tasks but also achieves state-of-the-art performance in visual-language tasks like OK-VQA, while maintaining robust general language skills.
