Executive Overview

Solstice-AI/Qwen3.8-27B-TTURBO-Cold-Fusion-709-L-Uncensored-mlx-oQ4e is the official Apple Silicon MLX release of DavidAU's Qwen3.8-27B-TWIN-TURBO-Fable-Cold-Fusion-709-L-Uncensored.

Engineered specifically for Apple Silicon Unified Memory architectures (M2, M3, M4, M5 Max / Ultra), this release couples oQ4e imatrix-guided mixed-precision with Solstice's proprietary 10-Level Cognitive Variable Thinking System and native Hardware Multi-Token Prediction (MTP).

Model Architecture Specifications:

• Base Precision: oQ4e mixed-precision with importance-matrix sensitivity allocation.
• Sensitive Layer Protection: Attention QKVO projections, MLP gate/up matrices, and normalization tensors strictly preserved at higher bit-depths (6-bit/8-bit/BF16).
• Multi-Token Prediction (MTP): Native Hardware MTP execution on Metal, providing 58–74 tok/s on consumer and pro Apple Silicon.
• Context Scaling: 262,144 tokens native context window.
• Refusal Vector Neutralization: Full orthogonalized abliteration across all safety refusal directions.
