Many GPUs support mixed-precision computation, allowing faster processing without major accuracy loss.

Quantization involves reducing numerical precision of neural network weights, often from 32-bit floating point to 16-bit or 8-bit formats. Community tools enabled Stable Diffusion to run using half-precision or optimized formats without significant quality loss. Reduced precision decreases memory consumption and increases inference speed on supported GPUs. These adaptations made high-quality generation accessible on mid-range consumer hardware. Engineering trade-offs balanced fidelity and efficiency. Numerical compression expanded reach. Optimization broadened adoption.
