GGUF fine-tune of a 27B Qwen model by DavidAU, with switchable instruct and reasoning modes and a built-in help system. Hugging Face lists it as image text to text. For local runners.

About

What it is: This repository holds a GGUF fine-tune of a 27B Qwen model, made by DavidAU. It adds the Turbo Brilliance 50X system, which lets you choose an instant instruct mode or a reasoning mode from small to large inside your prompt. Hugging Face lists 27.3B parameters, about 13.7 GB at 4-bit, and the task as image text to text.

Who it suits: People who run large models on their own computer and like to choose how much the model thinks. The card says the systems only start when you ask for them. Otherwise the model runs with its normal Qwen modes.

Title: Who uses it, and how
Industry | Who uses it | How they use it | Example
Local AI | Hobbyists | Pick a short or long reasoning mode per prompt | Use instruct mode for a quick fact and a reasoning mode for a puzzle
Software | Developers | Call the model through a local API | Switch modes with the same keywords in requests
Research | Tinkerers | Compare precision levels and modes | Run the same task at 4-bit and at 8-bit
Writing | Creators | Get focused drafts with fewer wasted tokens | Try one mode, then a second mode, on the same prompt

Skip it if you need audited benchmark results, because the card's quality claims come from its author and this page shows only part of the card.

Where to use it:

• A runner that loads GGUF files, on Windows, macOS or Linux
• Chat, where you pick the mode in your prompt
• An API or vLLM, where the card says modes switch the same way
• Windows, macOS or Linux for downloading the files, with Python

Use case | Who | What they get back
Quick answers | Hobbyists | An instant reply from an instruct mode
Hard problems | Developers | A longer answer from a reasoning mode
Mode comparison | Tinkerers | Several answers to one prompt, one per mode

How to set it up: You need Python and pip to download the files, and a runner for GGUF models. The card is cut on this page, so its full run steps and sampler settings are not shown here. Follow your runner's own instructions for loading a GGUF file.

• Python and pip
• A GGUF runner
• About 13.7 GB of disk space at 4-bit, per Hugging Face, and more for larger quants
• A computer with enough memory for a 27B model

1. Install the Hugging Face hub library.
2. Download the repository.
3. Load a quant in your runner and read the card for its settings.

pip install -U huggingface_hub
hf download DavidAU/Qwen3.8-27B-Jumbo-Fusion-IQ-747-900-Turbo-Brilliance-50X-Reasoning-Instruct-NEO-MAX-MTP-GGUF

How to use it: Write the mode you want into your prompt, then ask your question. The card says there are no buttons, because you pick the mode in the prompt or through the API. A help system built into the model can suggest which modes suit a task and in what order.

Tool | What it does
Instruct modes | Give an instant answer with no long thinking
Reasoning modes | Think for a little or a lot, from tiny to large
Xhigh modes | Go beyond the default Qwen reasoning, with combined versions
Help system | Advises on which mode fits your task

Example: You ask a quick factual question in instruct mode and get an instant reply. Then you ask a hard logic puzzle in a reasoning mode and let the model think longer. You compare both answers and keep the one that fits.

For newcomers and experts: If you are new, try the 4-bit file with the default settings first. Only after that, add a mode to your prompt and compare the answers.

For people in the field, the author reports arc-c and ARC-E scores for this fine-tune, plus a drop in thinking tokens. Those figures are the author's own, and this page cannot show the tables behind them. Treat them as claims to test on your own tasks.

Good to know:

Title: Author-reported arc-c score by precision
BF16: 747 pts
8-bit: 744 pts
4-bit: 742 pts

• License: Apache 2.0
• Cost to run: none named, you use your own computer
• Data it reaches: it downloads files from Hugging Face, and the card names nothing else it touches
• Not for: work that needs verified benchmarks or a documented stable release
• The card claims the model uses fewer thinking tokens than a normal Qwen mode, which you should check yourself
