About Qwen3.8-27B-Uncensored
Qwen3.8-27B-Uncensored (orcarouter) is a GGUF model based on orcarouter/Qwen3.8-27B-Uncensored on Hugging Face. GGUF files are published by 2 sources (bartowski/orcarouter_Qwen3.8-27B-Uncensored-GGUF, orcarouter/Qwen3.8-27B-Uncensored-GGUF). It has about 27.3B parameters, the qwen35 architecture, a maximum context length of 262,144 tokens (values written in the GGUF).
There are 28 quantizations, with file sizes from 8.88 GB (IQ2_XXS) to 54.7 GB (BF16) (actual sizes on Hugging Face).
Running Q4_K_M (17.8 GB) with an 8,192-token context needs an estimated 19.5 GB of memory, and an estimated 21.2 GB at 32,768 tokens. For 8,192 tokens, a GPU with 24 GB or more of VRAM (such as GeForce RTX 3090 Ti, GeForce RTX 4090), or a Mac with 24 GB or more of unified memory, is a rough guide (macOS caps how much memory the GPU can use, so leave some headroom). The smallest, IQ2_XXS (8.88 GB), needs an estimated 10.6 GB at 8,192 tokens.
The original model is licensed under Apache License 2.0, which allows commercial use (keep the license text and copyright notice when redistributing). Check the original license for the terms of use. An mmproj file for image input is also available.

File sizes are the actual values on Hugging Face. Memory is estimated for each context length (KV cache f16). The formula is in How memory is calculated.
All memory figures are Estimated (KV cache f16). It should run on a setup with at least this much VRAM (or Mac unified memory). Click a value to see the devices and models that fit that amount (Find by GPU / Mac).
2 sources publish GGUF files of this model. Quantization types and file sizes differ slightly between sources, so there is a table for each source below.
Using image input: This model supports image input. To use images, an mmproj file is loaded as well.
About the "quality guide" (how far a quantization drifts from the original)
For each quantization type, how far the output drifts from the original model, grouped into six levels from values llama.cpp measured on Llama-3-8B.
The value is mean KLD (the difference between the original and quantized model in next-token probabilities); smaller means closer to the original. Quantizations made with an imatrix (importance data) come out slightly smaller. Levels use the value without an imatrix (or with one, for types that only have that).
These values were not measured on this model. Larger models and MoE models tend to drift less with the same type. Distributor-specific mixed types (such as UD-Q4_K_XL) cannot be matched by type name alone, so they show "-".

Generation speed on common GPUs and Macs (estimated)
A rough guide to how fast Q4_K_M (17.8 GB) generates text. Each token reads the model weights once, so the upper limit is memory bandwidth ÷ file size. The guide is 60–80% of that, where most published measurements fall.
| Device | Memory bandwidth | Guide (tokens/s) Estimated | Upper limit |
|---|---|---|---|
| Radeon RX 7900 XT 20 GB | 800 GB/s | 27–36 | 45 |
| Radeon RX 7900 XTX 24 GB | 960 GB/s | 32–43 | 54 |
| GeForce RTX 5090 32 GB | 1,792 GB/s | 60–81 | 101 |
| Apple M4 32 GB | 120 GB/s | 4.1–5.4 | 6.8 |
| Apple M4 Pro 48 GB | 273 GB/s | 9.2–12 | 15 |
| Apple M5 Ultra 96 GB | 1,200 GB/s | 41–54 | 68 |
Estimates only. Prompt processing speed (limited by compute) is not included. Longer contexts and offloading part of the model to the CPU make it slower. Macs are shown only when installed memory is at least 4/3 of what is needed. Devices without published bandwidth (some GeForce cards, etc.) are not shown.

How to run
Mainline llama.cpp can load this model's format (qwen35) from b7990 (Feb 10, 2026) onward. Ollama and LM Studio bundle llama.cpp internally, so an older app fails to load it with errors such as "unknown model architecture". If that happens, update the app.
Example commands using Q4_K_M. To use another quantization, replace the name with one from the table above. Commands for files from other sources are in each source's section. How to run local LLMs
Ollama
Run it by pointing directly at the GGUF on Hugging Face.
ollama run hf.co/bartowski/orcarouter_Qwen3.8-27B-Uncensored-GGUF:Q4_K_M
llama.cpp
Pass the repository and quantization name to llama-server (or llama-cli) with -hf.
llama-server -hf bartowski/orcarouter_Qwen3.8-27B-Uncensored-GGUF:Q4_K_M
LM Studio
Paste bartowski/orcarouter_Qwen3.8-27B-Uncensored-GGUF into the search box, download it, and choose the quantization from the file list.
