About MOSS-Music-8B-Instruct
MOSS-Music-8B-Instruct is a GGUF model based on OpenMOSS-Team/MOSS-Music-8B-Instruct on Hugging Face. GGUF files are published by 2 sources (scragnog/MOSS-Music-8B-Instruct-GGUF, nerualdreming/MOSS-Music-8B-Instruct-GGUF). It has the moss-aud architecture (values written in the GGUF).
There are 3 quantizations, with file sizes from 1.72 GB (F16) to 16.4 GB (F16) (actual sizes on Hugging Face).
Running F16 (1.72 GB) with an 8,192-token context needs an estimated 3.78 GB of memory, and an estimated 7.40 GB at 32,768 tokens. For 8,192 tokens, a GPU with 4 GB or more of VRAM (such as Arc A310, Arc A370M), or a Mac with 4 GB or more of unified memory, is a rough guide (macOS caps how much memory the GPU can use, so leave some headroom).
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.

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.
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 F16 (1.72 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 |
|---|---|---|---|
| Arc A370M 4 GB | 112 GB/s | 39–52 | 65 |
| Arc A770 (8GB) 8 GB | 512 GB/s | 178–238 | 297 |
| GeForce RTX 5090 32 GB | 1,792 GB/s | 623–831 | 1,039 |
| Apple M2 8 GB | 100 GB/s | 35–46 | 58 |
| Apple M2 Pro 16 GB | 200 GB/s | 70–93 | 116 |
| Apple M5 Ultra 96 GB | 1,200 GB/s | 418–557 | 696 |
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.
