Two months back, Apple, in collaboration with Columbia University, quietly unveiled Ferret, a new multimodal large language model adept at referring and grounding.
Check out the GitHub repository here.
Ferret can refer to image regions in any free-form shape and automatically establish grounding for text deemed groundable by the model.
The researchers have curated the GRIT dataset for model training. The dataset includes 1.1 million samples that contain rich hierarchical spatial knowledge, with 95K hard negative data to promote model robustness.
They also said that the resulting model achieved superior performance in classical referring and grounding tasks and greatly outperformed existing MLLMs in region-based and localisation-demanded multimodal chatting.
“Our evaluations also reveal a significantly improved capability of describing image details and a remarkable alleviation in object hallucination,” the researchers said that Ferret, like most MLLMs, may produce harmful and conunterfactual reponses.
Citing LISA, the researchers said they plan to enhance Ferret to output segmentation masks and bounding boxes.
The Significance of Ferret’s Stealthy Debut
Apple’s strategic move to release Ferret without a formal announcement speaks volumes about the company’s dedication to staying at the forefront of multimodal AI. The unexpected embrace of open-source development departs from Apple’s traditional closed-door approach, setting the stage for potential collaboration and community-driven advancements.
Talking about its functionality, it is elegantly simple yet powerful. Beyond identifying elements within an image, the model draws connections to formulate responses to user queries. This opens up possibilities in image search, accessibility, and other applications where nuanced contextual understanding is crucial.
Ferret’s versatility is further enhanced by a spatial-aware visual sampler capable of handling various sparsity patterns associated with different shapes. Ferret accommodates diverse regional inputs, including points, bounding boxes, and free-form shapes.
