Cisco has released an open-source tool "to trace the origins of AI models," reports SC World , "and compare model similarities for great visibility into the AI supply chain." [ Cisco's Model Provenance Kit ] is a Python toolkit and command-line interface (CLI) that looks at signals such as metadata and weights to create a "fingerprint" for AI models that can then be compared to other model fingerprints to determine potential shared origins. "Think of Model Provenance Kit as a DNA test for AI models," Cisco researchers wrote. "[...] Much like a DNA test reveals biological origins, the Model Provenance Kit examines both metadata and the actual learned parameters of a model (like a unique genome that comprises a model), to assess whether models share a common origin and identify signs of modification." The tool aims to address gaps in visibility into the AI model supply chain.…
