Qwen3.8-27B-TURBO NEO-CODER (Official Clean GGUF Suite)

Official Solstice-AI Release • Standard Clean UD 3.0 Matrix • Multi-Token Prediction (MTP) Speculative Tiers • Pure BF16 Multimodal Vision Projector

Original Architecture by Qwen / Alibaba Cloud • Uncensored Weights by DavidAU • Curated & Packaged by Solstice-AI

Model Summary

Solstice-AI/Qwen3.8-27B-TURBO-Fable-Cold-Fusion-NEO-CODER-GGUF contains the official clean GGUF suite of Qwen3.8-27B NEO-CODER, bringing DavidAU's latest coding and agentic prompt engineering optimizations into standard, clean UD 3.0 GGUF binaries.

Key NEO-CODER Capabilities:

Dynamic Reasoning Effort Controls (reasoning_effort):
- medium: Suppresses default system prompt injection for direct, unrestricted coding execution and SWE-bench compatibility.
- xhigh: Injects deep-reasoning verification tags (<thought>) for complex algorithmic design and proofs.
Deterministic XML Tool Calling: Pre-configured for <tool_call><function=...><parameter=...></function></tool_call> execution.
Pure BF16 Vision Transformer (mmproj-BF16.gguf): Standalone 16-bit multimodal vision projector with zero FP16 underflow risks.
Multi-Token Prediction (MTP) Speculative Tiers: Bundles specialized MTP models (speculative-mtp/) and DSpark drafters (speculative/).
