I love a cozy hoodie. This one from #DeepMind is cozy and subtle enough to wear outside of the house.

Best team-swag has to be the Nano Banana jumper. Unique design, great box too (I kept it for months, "just in case").

A close 2nd was the Robotic Android figurine from @ptruiz.bsky.social. The spanner and laptop accessories are cute af. Not sure it's visible but the laptop is showing an object segmentation case.

Probably my favourite was this custom @jeffdean.bsky.social and Sanjay Gemmahat Lego set, holding the Map reduce paper. Thanks @developers.google.com!

The vectors themselves come from residual activations across every layer in response token generation, then they evaluate which layer is the most important per-trait in order to "subtract evil" or w/e later on, efficiently.
