Qwen3.8-Flash-Next — GGUF Quantizations

Original Model quant-kit

Quantized GGUF versions of Qwen3.8-Flash-Next

Works with llama.cpp · Ollama · LM Studio


⚡ The Model Architecture

Qwen3.8-Flash-Next is an incredibly powerful 125B parameter Mixture-of-Experts (MoE) model featuring a massive 51B N-gram embedding table. Despite its massive total size, its sparse architecture only activates ~6B parameters per token, making it blazingly fast during inference!

This GGUF was quantized to Q4_K_M to preserve maximum intelligence while shrinking the massive 360GB original size down to a highly efficient 111GB footprint.


📦 Available Files (Sharded)

Because this model is so large, the Q4_K_M GGUF has been split into 3 shards to bypass the 50GB file size limit.

Filename Size RAM Required Quant Quality
Qwen3.8-Flash-Next-Q4_K_M-00001-of-00003.gguf 45.0 GB - Q4_K_M ⭐⭐⭐⭐
Qwen3.8-Flash-Next-Q4_K_M-00002-of-00003.gguf 45.0 GB - Q4_K_M ⭐⭐⭐⭐
Qwen3.8-Flash-Next-Q4_K_M-00003-of-00003.gguf 21.0 GB - Q4_K_M ⭐⭐⭐⭐

⚠️ IMPORTANT: You must download all 3 files into the same folder! When loading the model in llama.cpp or Ollama, simply point the program to the first file (...00001-of-00003.gguf) and it will automatically detect and stitch together the rest of the shards during inference.

(System RAM Warning: You will need at least 128GB of Unified Memory (Mac) or System RAM/VRAM to run this model without severe swapping).


🚀 How to Use

llama.cpp CLI

Make sure all 3 shards are in the same directory.
