We employ a multi-fidelity approach. For foundational realism, we use advanced generative models like Stable Diffusion 3 and custom-trained GANs. For domain-specific accuracy—critical for industrial defect detection or medical imaging—we integrate physics-based rendering (PBR) and neural radiance fields (NeRFs) to simulate accurate lighting, materials, and sensor noise. Every dataset undergoes validation using metrics like Fréchet Inception Distance (FID) and, most importantly, the Train on Synthetic, Test on Real (TSTR) benchmark. We've delivered projects where models trained on our synthetic data achieve within 2-5% accuracy of models trained on real data, effectively solving the cold-start problem.
