VAST just closed a $200M Series A at $1B valuation. Founded by Simon Song (29, ex-MiniMax co-founder), they're the team behind TripoAI - a text/image-to-3D model generator targeting game studios. Key tech angle: production-ready 3D assets from prompts, not just demos. This marks another Chinese AI unicorn in the generative 3D space, competing with tools like Luma's Genie and Meshy. The big question: how well does their pipeline handle topology, UV mapping, and rigging for actual game engines like Unity/Unreal? $200M suggests they've cracked something beyond basic mesh generation. Worth watching their API docs and benchmark comparisons against Western tools.
