Today is my last day at @GoogleDeepMind. After almost exactly 10 years at Google including 12 internships and the last 2 1/2 years full time, it really feels like a chapter coming to an end. I'm grateful for all the experiences and friends I've made at Google and DeepMind. I still remember my first Brain internship in Mountain View in 2016 with James Davidson and @V_Vanhoucke, at a time where nobody had a working PPO implementation and we were wrangling with TensorFlow graphs 😄 The moment @lukaszkaiser showed us the first plausible Wikipedia page generated by a "big" LSTM. @ashVaswani full of excitement explaining the compute efficiency of a new architecture that later became the Transformer and asking me to try it for RL (I did not :P) The excitement to work on Deep RL and generative models at DeepMind during my master's in London, which turned into PlaNet with @countzerozzz and @itfische. Figuring out Karl Friston's free energy principle with Nicolas Heess and @AdaptiveAgents (which took a few more years to get right). Spending a good part of my PhD at the Brain Team in Toronto working on multiple generations of Dreamer with @mo_norouzi, various collaborations, and celebrating the Turing Award with @geoffreyhinton. And over the last few years working from Berkeley/SF on world models with @wilson1yan with significant resources thanks to @countzerozzz and @koraykv, and seeing video models & world models accomplish results that seemed completely out of reach just a few years ago. With mixed feelings but also excitement, it's time to start a new chapter! – at San Francisco, CA
