About Qwen2.5-72B-Instruct-abliterated

Qwen2.5-72B-Instruct-abliterated is a GGUF model based on Qwen/Qwen2.5-72B-Instruct on Hugging Face. GGUF files are published by zetasepic/Qwen2.5-72B-Instruct-abliterated-GGUF. It has about 72.7B parameters, the qwen2 architecture, a maximum context length of 32,768 tokens (values written in the GGUF).

There are 3 quantizations, with file sizes from 37.7 GB (Q3_K_M) to 64.3 GB (Q6_K) (actual sizes on Hugging Face).

Running Q4_K_M (47.4 GB) with an 8,192-token context needs an estimated 50.9 GB of memory, and an estimated 59.0 GB at 32,768 tokens. For 8,192 tokens, a GPU with 48 GB or more of VRAM, or a Mac with 48 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, Q3_K_M (37.7 GB), needs an estimated 41.2 GB at 8,192 tokens.

The original model is licensed under Qwen License Agreement, which allows commercial use with conditions such as scale or purpose. Check the original license for the terms of use.

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 (47.4 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
Apple M5 Pro 64 GB 307 GB/s 3.9–5.2 6.5
Apple M2 Max 64 GB 400 GB/s 5.1–6.7 8.4
Apple M5 Ultra 96 GB 1,200 GB/s 15–20 25

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.
