At its Tokyo symposium "From World Models to Real-World AI" (400+ attendees), Sakana AI announced it is moving into in-house pretraining. Chief Scientist Takuya Akiba unveiled the "Sakana Sawara" (tentative) LLM series, with the first small model slated for spring 2027. Chief Scientific Advisor Jürgen Schmidhuber — pioneer of pre-training/distillation, modern world models, artificial curiosity, and LSTM co-author — gave the keynote and a fireside chat with CEO David Ha, who argued that foundation models are among the fastest-depreciating financial assets in history and that scaling alone isn't the only path: "intelligence is born from constraints." Sessions also covered open-ended autonomous discovery (Robert Tjarko Lange) and world models & physical AI (Stefania Druga, Sebastian Risi); a full English report is available.
