About Qwen3-14B-abliterated

Qwen3-14B-abliterated (richardyoung) is a GGUF model based on Qwen/Qwen3-14B on Hugging Face. GGUF files are published by richardyoung/Qwen3-14B-abliterated-GGUF. It has about 14.8B parameters, the qwen3 architecture, a maximum context length of 40,960 tokens (values written in the GGUF).

There are 6 quantizations, with file sizes from 6.88 GB (IQ3_M) to 29.5 GB (F16) (actual sizes on Hugging Face).

Running Q4_K_M (9.00 GB) with an 8,192-token context needs an estimated 11.2 GB of memory, and an estimated 15.2 GB at 32,768 tokens. For 8,192 tokens, a GPU with 12 GB or more of VRAM (such as GeForce RTX 3080 Ti, GeForce RTX 5070), or a Mac with 12 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, IQ3_M (6.88 GB), needs an estimated 9.07 GB at 8,192 tokens.

File size and estimated memory per quantization

  • Up to 8 GB
  • Up to 16 GB
  • Up to 24 GB
  • Up to 48 GB
  • Up to 128 GB
  • More

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).

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 (9.00 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 7600 XT 16 GB 288 GB/s 19–26 32
Radeon RX 6950 XT 16 GB 576 GB/s 38–51 64
GeForce RTX 5090 32 GB 1,792 GB/s 119–159 199
Apple M2 16 GB 100 GB/s 6.7–8.9 11
Apple M2 Pro 16 GB 200 GB/s 13–18 22
Apple M5 Ultra 96 GB 1,200 GB/s 80–107 133

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 (qwen3) from b5092 (Apr 9, 2025) 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. How to run local LLMs

Ollama

Run it by pointing directly at the GGUF on Hugging Face.

ollama run hf.co/richardyoung/Qwen3-14B-abliterated-GGUF:Q4_K_M

llama.cpp

Pass the repository and quantization name to llama-server (or llama-cli) with -hf.

llama-server -hf richardyoung/Qwen3-14B-abliterated-GGUF:Q4_K_M

LM Studio

Paste richardyoung/Qwen3-14B-abliterated-GGUF into the search box, download it, and choose the quantization from the file list.
