Descriptions:
Google’s Gemini 3.1 Pro is reviewed across an extensive range of capability tests, accessible via the Gemini app by selecting the Pro tier. The video covers creative design, 3D rendering, music composition, physics simulation, and multimodal video understanding in sequence, making it a broad practical evaluation of the model’s current state.
Notable demonstrations include a mobile OS concept called Fluid OS with eight AI-powered apps, visual comparisons of 3D pagoda and object renderings between Gemini 3.1 Pro and its predecessor Gemini 3 (with 3.1 Pro showing substantially more geometric detail), and a coherent 32-bar piano opus generated through a custom piano roll interface — contrasted against GLM-5’s more dissonant output on the same prompt. A particularly striking test involves uploading a video about Japan earthquakes with no text description and having the model autonomously build a functional interactive earthquake simulation map for Japanese cities.
SVG animation quality and lighting physics simulations with multiple metallic spheres are also compared between model versions. The reviewer positions Gemini 3.1 Pro as the current leader for canvas-based code generation and 3D spatial reasoning, giving Google a strong entry in the competitive frontier model landscape of early 2026.
