Gemini Models Advance on Geisel Library Reconstruction

EnactraAI posted a video of an infographic displaying Gemini 3.1 Pro, 3.5 Flash, 3.7 Flash, and 3.8 Flash outputs. The sequence shows progressive refinement in a spatial world simulation attempting to reconstruct Geisel Library from a reference photo, with the 3.8 Flash render forming the building's iconic geometry. Academic Lianhui Qin quoted that Gemini 3.8 is substantially better and retweeted the original post. The demonstration focuses on visible spatial intelligence gains across the model iterations shown.
