Gemini 4 Krypton tops visual coding benchmarks

Google's heavy allocation of test-time compute in Krypton signals a major strategic pivot toward spatial and visual reasoning. If these early arena benchmarks hold, 3D web development and visual coding will become the next frontier battleground.

• –Krypton deploys significantly more reasoning compute than previous checkpoints, enabling procedural 3D environments and complex multi-layer SVG graphics
• –Spatial reasoning focus addresses coordinate hallucinations that plague standard models during Three.js and WebGL generation
• –Blind arena comparisons show Krypton matching Anthropic's Claude Opus 5.5 and Fable 5.2 in dense frontend synthesis
• –Visual code generation is shifting from simple layout boilerplate to complex procedural and spatial rendering
