Gemini Nano is on-device right now - on the Pixel 8 Pro. This potentially makes it vulnerable to attempts to extract the weights from such a device and publish them. Alternativelly, Google may decide to open source the weights.

This question Resolves to YES if between now and the end of 2024 it is possible for a member of the public to download the weights of Gemini Nano, or an updated version, in an unprotected format.
