About qwen38-flash-next-v3

qwen38-flash-next-v3 is a GGUF model based on Qwen/Qwen3.8-Flash-Next on Hugging Face. GGUF files are published by nitinpanj/qwen38-flash-next-v3. It has about 176.9B parameters, the qwen4exp architecture, a maximum context length of 262,144 tokens (values written in the GGUF).

There is one quantization, Q4_0, with a file size of 103 GB (actual size on Hugging Face).

Running Q4_0 (103 GB) with an 8,192-token context needs an estimated 104 GB of memory, and an estimated 105 GB at 32,768 tokens. For 8,192 tokens, a GPU with 128 GB or more of VRAM, or a Mac with 128 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 Qwen Community License 1.0, 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 "-".

License and commercial use

Qwen Community License 1.0 Conditional

Allows commercial use. However, companies (including affiliates) that offer the model to third parties as a service (Model as a Service, e.g. via an API) or run an AI assistant business for coding or office work need a separate license from Qwen before commercial use (internal-only use is excluded). Products with over 100 million monthly active users or over USD 20 million in monthly revenue must display the model name.

Based on the license on the original model's Hugging Face page. Original license text (checked Oct 18, 2026)

How to run

Mainline llama.cpp can load this model's format (qwen4exp) from b10660 (Aug 27, 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_0. 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/nitinpanj/qwen38-flash-next-v3:Q4_0

llama.cpp

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

llama-server -hf nitinpanj/qwen38-flash-next-v3:Q4_0

LM Studio

Paste nitinpanj/qwen38-flash-next-v3 into the search box, download it, and choose the quantization from the file list.

Frequently asked questions

How much memory do I need to run qwen38-flash-next-v3 (Q4_0)?
The file size is 103 GB (measured). With a 8,192-token context, the estimated memory including the KV cache is 104 GB. The formula is published at https://localllm.az-arte.com/en/guide/memory-calculation.
Can qwen38-flash-next-v3 be used commercially?
The original model's license is Qwen Community License 1.0 (Commercial use with conditions).Allows commercial use. However, companies (including affiliates) that offer the model to third parties as a service (Model as a Service, e.g. via an API) or run an AI assistant business for coding or office work need a separate license from Qwen before commercial use (internal-only use is excluded). Products with over 100 million monthly active users or over USD 20 million in monthly revenue must display the model name. Check the original license text before deciding.
Does qwen38-flash-next-v3 run in 8 GB, 12 GB, 16 GB or 24 GB of VRAM?
8 GB: no quantization fits; 12 GB: no quantization fits; 16 GB: no quantization fits; 24 GB: no quantization fits (estimated at 8,192 tokens with an f16 KV cache, files from the most-downloaded source).
What is the command to run qwen38-flash-next-v3 with Ollama?
Run "ollama run hf.co/nitinpanj/qwen38-flash-next-v3:Q4_0" to use the GGUF on Hugging Face directly. To use another quantization, replace the name at the end.
