Károly Zsolnai-Fehér demonstrates Sonnet 5.5 adapting part of an existing physics-simulation research implementation into a single HTML file and matching selected experiments. The review also shows graphics examples, while explicitly noting that the physics port is not a reproduction of the entire research system.
Károly Zsolnai-Fehér compares the reported cost and quality of recent models and argues that training efficiency can matter more than parameter count alone. The claim that comparable frontier capability may eventually run on laptops or phones is his extrapolation, not a verified statement about these models' sizes or an available local release.
