Apple has introduced Ferret-UI, a groundbreaking development in artificial intelligence, aimed at significantly enhancing Siri's capabilities. Developed by Apple researchers K You, H Zhang, E Schoop, F Weers, A Swearngin, J Nichols, Y Yang, Z Gan in 2024, Ferret-UI leverages multimodal large language models (MLLMs) to improve AI's interaction with mobile applications. This technology enables Siri to understand and execute tasks related to user interface screens with unprecedented precision. The introduction of Ferret-UI, detailed in a paper by Apple and covered by David Snow, could make Apple the frontrunner in the AI assistant space. Ferret-UI's ability to perform precise referring and grounding tasks, while interpreting open-ended language instructions, represents a significant advancement in making AI interact more human-like with mobile applications. Additionally, Ferret-UI will be presented at the International Conference on Learning Representations (ICLR), highlighting its potential to revolutionize digital assistants' utility and efficiency.
