 ## MoE Support Matrix
 
-In MoE, the weights are pre-quantized to mxfp4. The activation can be in either bf16 (Hopper) or mxfp8 (Blackwell), with similar accuracy.

+In MoE, the weights are pre-quantized to mxfp4. The activation can be in either bf16 (Hopper) or mxfp8 (Blackwell), with similar accuracy. FP8 activation with per-tensor scaling factor has limited support. Note that the per-tensor scaling factor needs to be calculated dynamically during inference with the official mxfp4 checkpoints, which may negatively impact perf. The configs in **bold** are the recommended configs for the official checkpoints.
