Summary A

GPT-6 Astra’s 3D modeling capability can generate production-ready CAD or game-ready meshes from text prompts in under 30 seconds. This collapses the cost of prototyping physical or virtual assets by 10–100×, but it also breaks existing content pipelines that assume manual review of every asset—expect false positives in automated QA and new attack surfaces for prompt-injected geometry.
