Model Summary
Solstice-AI/GLM-5.3-Flash-UNCENSORED-mlx-oQ8e is the official oQ8e mixed-precision release of the uncensored 320B foundation model, GLM-5.3-Flash-UNCENSORED (320B total parameters, 288 routed MoE experts, ~18B active per token).
Mixed-Precision Quantization Architecture:
- Base Precision: 8-bit affine (group_size=64).
- Target bpw: ~8.6 bpw.
- Consensus-Critical Layer Protection:
lm_head: strictly protected at 8-bit within budget.- MoE Routers & Gate Projections (
mlp.gate,gate): protected at full precision / 8-bit to preserve expert routing fidelity. - 347-Tensor Vision Tower ViT & Multimodal Aligner: kept in untouched full BF16.
- Attention Sinks & Hyper-Connection Tables (
hc_*): kept in full BF16/FP32.
- Native 1M Context Window: 1,048,576 tokens native context.
- Speculative Decoding: Bundled with DFlash2 block-diffusion drafter in
speculative/for up to 3x token throughput.
