FLUX.2-klein-4B Q4_0

This file is exactly 2,460,394,048 bytes — 2.29 GiB / 2.46 GB at an effective 5.079 bits per weight. The nominal rate for Q4_0 is lower; mixed-precision tensors make the real figure higher, always.

A quantization label names a mixture, not a uniform precision. Attention and output tensors are routinely kept at higher precision than the label implies, which is exactly why the effective bits-per-weight above exceeds the nominal rate.
