FLUX.2-klein-4B Q4_K_M

This file is exactly 2,604,311,104 bytes — 2.43 GiB / 2.60 GB at an effective 5.376 bits per weight. The nominal rate for Q4_K_M 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.
