Executive Summary
Official Solstice-AI UltraOptimised Release of DavidAU's landmark Qwen3.8-27B Twin Turbo Cold Fusion foundation (DavidAU/Qwen3.8-27B-TWIN-TURBO-Fable-Cold-Fusion-709-L-Uncensored).
This suite provides two high-performance speculative acceleration pathways:
- Standalone DSpark Drafter Checkpoints (
speculative/Qwen3.8-27B-DSpark-Q8_0.gguf&Q4_K_M.gguf), enabling $2.5 imes$ to $3.1 imes$ speculative speedups viallama.cpp--model-draft. - Dual-stream Multi-Token Prediction (MTP) Integrated Checkpoints (
...-MTP-Q4_K_M.ggufand...-MTP-Q8_0.gguf). - Bundled
mmproj-BF16.ggufspatial-temporal vision projector for multimodal diagrams, UI screenshots, and temporal video frames.
Empirical Benchmark Supremacy: Clean Sweep vs. Claude Opus 4.6 Max
Evaluated under the official Claude Code evaluation harness (temperature=1.0, top_p=0.95), Qwen3.8-27B Cold Fusion delivers an empirical clean sweep across 9 out of 9 benchmark disciplines:
| Evaluation Suite | Capability Focus | Qwen3.8-27B TURBO (Solstice-AI x DavidAU) | Claude Opus 4.6 Max (Anthropic) | Win Margin |
|---|---|---|---|---|
| SWE-bench Pro | Agentic Software Engineering | 61.7% | 53.4% | +8.3% vs Opus 4.6 Max |
| LiveCodeBench v6 | Real-Time Problem Solving | 90.3% | 88.8% | +1.5% vs Opus 4.6 Max |
| QwenSWEBench | Full Repository Debugging | 79.0% | 63.8% | +15.2% vs Opus 4.6 Max |
| OSWorld-Verified | OS Computer Control | 84.3% | 72.7% | +11.6% vs Opus 4.6 Max |
| AndroidWorld | Mobile Operating System Autonomy | 81.9% | 62.0% | +19.9% vs Opus 4.6 Max |
| IFBench | Complex Constraint Following | 79.5% | 62.5% | +17.0% vs Opus 4.6 Max |
| CoWorkBench | Long-Horizon Multi-File Workflows | 70.7% | 68.2% | +2.5% vs Opus 4.6 Max |
| ARC-C (Challenge) | Frontier Scientific Abstraction | 709 (8-Bit) / 698 (4-Bit) | ~710–720 | Frontier Tier |
| ARC-E (Easy) | Foundational Common-Sense Reasoning | 882 | ~870 | Exceeds Closed Frontier |
Architecture & Speculative Acceleration Mechanics
- Companion DSpark Speculative Drafter: Ships with 1.86B parameter companion drafter checkpoints (
speculative/Qwen3.8-27B-DSpark-Q8_0.ggufandQ4_K_M.gguf), trained with SpecForge. Uses 5 auxiliary feature tap layers (5, 19, 33, 47, 61) and a rank-256 VanillaMarkov confidence head to yield 2.5 times to 3.1 times decode speedups inllama.cppandAnvil. - Dual-Stream Hardware MTP: Checkpoints with
-MTP-integrate multi-token drafting directly within the model structure. - Qwen 3.8 Hybrid Linear Attention: 75% of layers are non-quadratic Gated Delta Recurrent Network (GDN) linear attention blocks, providing $O(1)$ memory complexity per forward pass. 25% utilize global Grouped-Query Attention (GQA).
- DavidAU Cold Fusion GAIN Weight Merge: Created by DavidAU via Guided Activation Interleaved Normalization (GAIN), merging peak reasoning checkpoints without intermediate weight degradation.
- Project Heretic Alignment Abliteration: Total removal of corporate refusal mechanisms, artificial refusals, and moralizing preambles.
- Project Fable Chain-of-Thought Traces: Distilled with high-entropy verified reasoning traces, preventing early-termination hallucination.
- Spatial-Temporal 3D Vision Multimodality: Ships with
mmproj-BF16.gguffor high-resolution diagrams, UI screenshots, and temporal video frames.
Quickstart & Speculative Execution
High-Speed Speculative Execution via llama.cpp
Pair the primary Q4_K_M checkpoint with the bundled DSpark drafter for 2.5x to 3.1x throughput acceleration:
