Psi-0.6: unified vision-language world model with adaptive "streams of thought"
Psi-0.6 (arXiv:2610.32177v1) is a unified vision-language world model that interleaves images, text, and explicit geometry/motion representations into shared-token "streams of thought" the model can generate and interpret. The paper reports zero-shot gains over leading open-weight models on multi-view spatial reasoning, supports counterfactual simulation (imagined scene generation/interpretation), and shows VQA accuracy improvements when reinforcement learning jointly optimizes use of intermediate representations.
