G4-PRISM-PRO — PRISM Dynamic Quantization

Gemma 4 31B-It PRISM-PRO-Dynamic-Quant

  • PRISM-PRO: Production model with full over-refusal and bias mechanisms completely removed using State of the Art PRISM pipeline.
  • DQ: Per-tensor-class mixed-precision allocation derived entirely from weight structure sensitivity analysis - not closed-gated Datasets.

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.

Usage

Refusal & Bias Removal

This model has been treated to remove bias, over-refusals and propaganda from the base google/gemma-4-31B-it using the State of The Art PRISM pipeline.
