Kimi K3.1 Pro model precision details revealed as inaccurate

By PulseAugur Editorial · [1 sources] ·

A technical analysis of the Kimi K3.1 Pro model revealed discrepancies in its reported bit precision. While the model page indicated 8-bit precision and the download badge suggested the same, a detailed calculation based on the checkpoint's file size and parameter count indicated an average of 4.49 bits per parameter. This suggests that not all weights within the model are quantized to 4-bit, with some layers maintained at higher precision due to quality considerations or size inefficiencies. AI

IMPACT Highlights the importance of verifying model quantization claims for accurate resource sizing and understanding model architecture.

    The model page said 8-bit. The checkpoint is 4.49 bits per parameter.

    <p>I was working out how much disk Kimi K3.1 Pro would need, and the model page gave me two numbers that cannot both be true. The card says <code>MXFP4 weights / MXFP8 activations</code>. The badge beside the download button says <code>8-bit precision</code>. So I added up the sh…
