PRISM-DQ Quantization
This model uses
PRISM-PRO Dynamic Quantization
— a proprietary per-tensor-class
mixed-precision allocation that assigns different quantization types to different
tensor classes based on 7 structural weight metrics.
Unlike uniform quantization (Q4_K_M, Q5_K_M), PRISM-DQ analyzes each tensor class's
sensitivity to quantization error and allocates precision where it matters most.
Attention projections receive higher precision than FFN layers, with block-level
overrides that protect early layers (high downstream error propagation).
No calibration data, no importance matrices, no training data required.
The result: BF16-equivalent quality at 5.02 bits-per-weight — a 68% size reduction
with zero measurable quality loss.
Download the GGUF file and load it in LM Studio. The model will be detected as Gemma 4 31B.
