Gemini 4 Hydrogen? AI Leaks, Demos and What’s Actually Known

A new codename can generate more certainty than the evidence deserves. This AI news roundup starts with the reported Hydrogen connection to Gemini 4 and keeps the model-identity claim separate from the examples people can actually inspect. We look at published visual tests, world-model research, local-model developments and practical coding updates. Pelican motion, voxel structures and diagram labels offer concrete details to check instead of relying only on a leaderboard headline. Anonymous checkpoint names and reported leaks remain unconfirmed where the video identifies them that way. Published community examples are not presented as our own tests. #AINews #Gemini #LocalAI
