Meta and Nvidia’s open models trail DeepSeek in reported 3D building tests
EnactraAI says it tested the models on BuildingBench, which measures reconstruction of real buildings from photographs.
TLDR
EnactraAI says Meta’s Muse Spark Open scored 56.9 on BuildingBench at an estimated median cost of $8.59 per task, while Nvidia’s Nemotron 3.5 Super VL scored 37.8 at $0.76. DeepSeek V4.1 Flash scored 72.9 at an estimated $2.33 per task. EnactraAI says both new models ran in Claude Code at max effort and neither reached the cost–quality frontier.
