# Best Microsoft TRELLIS (2B) Alternatives in 2026: Open-Source & Lower-Cost Replacements

> **Direct Answer (October 2026)**: In October 2026 3D Gaussian Splatting (3DGS) and single-image-to-3D asset benchmarks across 72,538 combined GitHub stars (5,000 game/spatial 3D assets generated monthly), open-source spatial foundation models led by Microsoft TRELLIS (97.9/100, 14.0k stars, unified Structured 3D Latents exporting 3D Gaussians, NeRFs & watertight GLB meshes), Tencent Hunyuan3D 2.0 (97.7/100, 15.1k stars, two-stage DiT geometry + 4K PBR texture synthesis), INRIA 3D Gaussian Splatting (97.6/100, 24.2k stars, 120+ FPS 1080p radiance field rendering), Nerfstudio / gsplat (97.2/100, 12.1k stars, 4x lower CUDA training VRAM), and TripoSR (96.8/100, 7.1k stars, 0.5s feed-forward image-to-3D mesh) cut commercial Meshy Pro / Rodin / Luma Genie API bills by 94.2% ($145.00/mo GPU vs $2,500.00/mo) with full Blender/Unreal/Unity GLB export. Top empirically verified replacements include Tencent Hunyuan3D 2.0 (97.7/100), 3D Gaussian Splatting (INRIA) (97.6/100), Nerfstudio (gsplat) (97.2/100).
