What it is¶

Qwen3.8-27B-Cold-Fusion-GAIN-V1.1 is a third-party fine-tune of Qwen3.8-27B released as GGUF quantizations for local inference.

• Text: generates text locally.
• Images: processes images when mmproj is present.
• Reasoning: provides three reasoning levels.
• Quantization: ships standard and MTP quants.

MTP requires checking token acceptance on your specific hardware. Test it locally against official Qwen3.8-27B on your own tasks instead of relying on author benchmarks.

Development line¶

• 2026-08-20 — Qwen3.8-27B-Cold-Fusion GGUF artifact linked. Apache-2.0 GGUF release with standard and MTP quants, including Q4_K_M.

What changed¶

2026-08-20 — DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF released: Apache-2.0 GGUF release with standard and MTP quants, including Q4_K_M.

The model card adds the full name, three reasoning modes (xhigh, medium, low), 256k context, and a separate mmproj requirement for images. The accessible card shows no publication date, so we do not claim a more precise source date.

We found no new dated steps tied to the development of this specific model.

How to use this¶

As of 2026-08-20, evaluate the linked GGUF artifact as a distinct Qwen derivative, checking its provenance, configuration, and capabilities before use.

1. Install llama.cpp and run the selected Q4_K_M build with llama serve -hf …:Q4_K_M, then check outputs on your task. — https://huggingface.co/DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF
2. For quick local execution, run ollama run hf.co/…:Q4_K_M. — https://huggingface.co/DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF
3. To process images, download one compatible mmproj file and place it next to the GGUF. — https://huggingface.co/DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF

Best practices¶

• Compare standard and MTP builds on your hardware; use standard quantization if token acceptance falls below 50%. — https://huggingface.co/DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF
• For MTP, keep temperature no higher than 1 and repetition penalty at 1 so speed does not degrade. — https://huggingface.co/DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF
• Test the model on your own tasks before deployment because the reasoning change is substantial. — https://huggingface.co/DavidAU/Qwen3.8-27B-Cold-Fusion-GAIN-V1.1-NM-DAU-NEO-MAX-MTP-GGUF

Superseded by this¶

• Nothing marked obsolete yet.

Still unknown¶

• The model card provides no creation date or commit history, so we cannot date the release more precisely than 2026-08-20.
• Author claims of preserved performance, fewer thinking tokens, and benchmark wins lack independent reproducible verification.
• No specific revision or commit links the Cold-Fusion weights to official Qwen/Qwen3.8-27B.
