Gemma 4 31B nails Gargantua test

Hot take: this is less a product launch than a stress test for whether a model can hold a physically grounded, shader-heavy, single-page 3D build together without collapsing into loops or broken output.

• –The prompt is a strong proxy for advanced coding capability because it combines graphics, physics approximation, interaction design, and packaging constraints in one shot.
• –The post’s main signal is comparative: Gemma 4 31B reportedly converged quickly, while the Qwen variants needed more iterations or failed outright.
• –Because this is self-reported Reddit evidence rather than a formal benchmark, it’s useful as a qualitative field test, not a definitive ranking.
• –The task highlights where local models still diverge sharply: stateful code generation, multi-part constraints, and visually coherent WebGL or canvas work.
• –For developers, the interesting part is not the black hole itself but the model’s ability to produce usable, self-contained front-end simulations under pressure.
