bf16
Brain Float 16
Definition
BF16 is a 16-bit floating-point format with the same exponent range as 32-bit float but reduced mantissa precision, making it well-suited for deep learning training. It avoids the numerical overflow issues common with FP16 while halving memory usage compared to FP32.
BF16 is natively supported on Google TPUs and modern NVIDIA GPUs (Ampere and later).
