TRELLIS 2, from Microsoft, is an open-source 3D generator that stands out for high-quality Gaussian-splatting visuals and flexibility in how it represents output, working from images or text. Under a permissive MIT license, it’s free to use and modify.
It’s best understood as a powerful research-grade foundation rather than a finished consumer app: you bring the GPU and the setup, and in return you get cutting-edge generation you fully control — ideal for experimentation, splatting-based visualization and custom pipelines.
If you want a polished UI, auto-rigging and one-click engine export, commercial tools like Meshy, Tripo or Rodin will get you there faster. But for teams comfortable with open tooling who want the latest techniques and zero licensing cost, TRELLIS 2 is a compelling option.
