Before I quantized Qwen3.8-27B, I ran tests to figure out which weight groups actually matter, rather than just looking at where the model falls apart (3 builds: Bedrock / Tightrope / Gambit).
Went with the same approach I used in my Qwen3.6 post. You quantize one weight group at a time, measure the KL divergence against the source model, and find where the real safe floor sits instead of just pulling a number out of thin air. Built a fresh imatrix specifically for this model. This round I pushed it one step
