Loss Scaling Free __link__ -

# Define the model model = nn.Sequential([...])

# PyTorch example with torch.autocast(device_type='cuda', dtype=torch.bfloat16): loss = model(input) loss.backward() # No loss scaling needed optimizer.step() loss scaling free

To understand why "loss scaling free" training is the new gold standard, it is important to look at the problems it solves: # Define the model model = nn

Because BF16's range matches FP32, gradients are extremely unlikely to underflow or overflow, allowing researchers to remove the GradScaler logic entirely from their training scripts. Key Benefits of Scaling-Free Training
