Could you build this?
No Porting a state-of-the-art 3D vision model (SAM 3D) to pure C++/GGML requires deep mathematical understanding of tensor operations and low-level hardware kernel programming.
What it would actually take: The project requires C++, GGML/llama.cpp-style tensor computation primitives, and custom compute kernels (CUDA, Metal, CPU SIMD). The hardest parts are decomposing PyTorch-specific 3D geometry operators, attention mechanisms, and camera projection math into pure C/GGML computation graphs, followed by quantization and memory layout optimization. This demands deep expertise in machine learning systems engineering and computer vision.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
