What is Qwen 3-Coder?

Qwen 3-Coder is Alibaba's MoE open-weights language model. Released in 2025-07, it ships in 2 sizes (30B, 480B) and is licensed Apache 2.0 (30B), custom (480B). The most popular use case is long-context code agent workflows.

VRAM and hardware

The smallest 30B size needs at least 18 GB VRAM; the largest 480B needs around 18 GB.

Size	Min VRAM (Q4_K_M)	Recommended VRAM	Tokens/sec on 3090
30B	18 GB	27 GB	~18 tok/s
480B	280 GB	420 GB	~10 tok/s

How to run Qwen 3-Coder locally

Option 1: Ollama (simplest)

ollama pull qwen-3-coder
ollama run qwen-3-coder

Option 2: Mullama (production)

mullama pull qwen-3-coder
mullama run qwen-3-coder

Option 3: llama.cpp (CLI)

# Download a GGUF from Hugging Face (search "qwen-3-coder gguf")
./llama-cli -m qwen-3-coder.Q4_K_M.gguf -p "Hello, AI!"

Option 4: Python with Mullama or llama-cpp-python

from mullama import Model, Context
model = Model.load("qwen-3-coder.Q4_K_M.gguf", n_gpu_layers=99)
ctx = Context(model, n_ctx=4096)
print(ctx.generate("Hello, AI!", 256))
