Increasing the bf16 threshold by a factor of 10 to 5e-2 is a significant change that could mask future precision regressions. To maintain test quality, it's important to keep thresholds as tight as possible.

If this large threshold is necessary due to limitations with bfloat16 on CPU, please add an inline comment to explain the reason. This provides valuable context for future developers and justifies the large value.

DTYPE_AND_THRESHOLDS = {"fp32": 5e-4, "fp16": 5e-3, "bf16": 5e-2}
DTYPE_AND_THRESHOLDS = {"fp32": 5e-4, "fp16": 5e-3, "bf16": 5e-2} # Increased for bf16 on CPU due to precision issues.
