Qwen3 Next 80B A3B Instruct — Hardware Requirements & GPU Compatibility

ChatFunctions

Qwen3 Next 80B A3B Instruct is a Mixture of Experts (MoE) model from Alibaba Cloud's Qwen 3 series, with approximately 81.3 billion total parameters and around 3 billion active parameters per forward pass. This extreme ratio between total and active parameters allows the model to encode extensive knowledge across its expert layers while maintaining very fast per-token inference, making it an unusually efficient design for its capability level. The model is instruction-tuned for general-purpose chat and requires VRAM proportional to its full 80B parameter count for weight loading, typically needing high-VRAM GPUs or quantized multi-GPU setups. Its low active parameter count results in fast generation speeds despite the large total model size. Released under the Apache 2.0 license.

Run Qwen3 Next 80B A3B Instruct

49.3 GB VRAM at 16K context

Works on macOS, Windows and Linux.

Install Ollama (Linux)
$curl -fsSL https://ollama.com/install.sh | sh
Install Ollama (macOS / Windows)
Download and run the app; it installs the ollama command.
Download Ollama ↗
Run Q4_K_M
$ollama run hf.co/unsloth/Qwen3-Next-80B-A3B-Instruct-GGUF:Q4_K_M
Raise the context window
Type it inside the chat. For the API server instead, start it with OLLAMA_CONTEXT_LENGTH=16384 ollama serve.
$/set parameter num_ctx 16384
A larger context needs more memory than the weights alone.
Use the API
Ollama serves its API on http://localhost:11434.

Works on macOS, Windows and Linux.

Install LM Studio
Desktop app for macOS (Apple silicon), Windows and Linux.
lmstudio.ai ↗
Download the model
In the app press Ctrl/Cmd + Shift + M and search qwen/qwen3-next-80b, then pick Q4_K_M. Or use the CLI (run LM Studio once first):
$lms get qwen/qwen3-next-80b@q4_k_m
Open on Hugging Face ↗
Load and chat
Open the model loader, select the model and set Context Length to 16384. Leave GPU offload at maximum if it fits.
Start the local server (optional)
$lms server start

Works on macOS, Windows and Linux.

Install llama.cpp (macOS)
MacPorts, Nix and conda-forge also work.
$brew install llama.cpp
Install options ↗
Install llama.cpp (Windows)
$winget install llama.cpp
Install llama.cpp (Linux)
Download the prebuilt llama-*-bin-ubuntu-* archive for your GPU backend (CPU, Vulkan) from the releases page, unpack it and run the binaries from that folder. Homebrew (brew install llama.cpp) and conda-forge also work on Linux.
llama.cpp releases ↗
Start the server
Downloads the model on first run. The chat UI and an OpenAI-compatible API are at http://localhost:8080.

Model Runner docs ↗
The quant tag after the repo is how Hugging Face cards write it; if your Docker version rejects it, drop the tag and pick the quant by repo.
Option B: llama.cpp server image (NVIDIA)
Needs the NVIDIA Container Toolkit. Models are cached in the llama-cache volume. Open http://localhost:8080.
$docker run --gpus all -p 8080:8080 -v llama-cache:/root/.cache ghcr.io/ggml-org/llama.cpp:server-cuda -hf unsloth/Qwen3-Next-80B-A3B-Instruct-GGUF:Q4_K_M -c 16384 -ngl 99 --host 0.0.0.0 --port 8080

Frequently Asked Questions

How much VRAM does Qwen3 Next 80B A3B Instruct need?

Qwen3 Next 80B A3B Instruct requires 49.2 GB of VRAM at Q4_K_M, or 163.1 GB at BF16. Full 262K context adds up to 3.1 GB (52.3 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 81.3B × 4.8 bits ÷ 8 = 48.8 GB

KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 3.5 GB (at full 262K context)

Can I run Qwen3 Next 80B A3B Instruct on a Mac?

Yes — Mac Studio M1 Max (32 GB) and 84 other Macs can run Qwen3 Next 80B A3B Instruct, the smallest at IQ2_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 49.2 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (64 GB).

Can I run Qwen3 Next 80B A3B Instruct locally?

Yes — Qwen3 Next 80B A3B Instruct can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Qwen3 Next 80B A3B Instruct?

At Q4_K_M, Qwen3 Next 80B A3B Instruct can reach ~97 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 3.3 GB active ÷ (8000 × 0.65) = 0.64 ms, plus 48 layers × 0.055 ms = 2.64 ms, so 1000 ÷ 3.28 ms = ~305 tok/s

Estimated speed at Q4_K_M (49.2 GB)

NVIDIA B200

~305 tok/s

NVIDIA B300

~305 tok/s

NVIDIA GH200 Grace Hopper Superchip

~271 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.

What's the download size of Qwen3 Next 80B A3B Instruct?

At Q4_K_M, the download is about 48.79 GB. The full-precision BF16 version is 162.65 GB. The smallest option (IQ2_XXS) is 22.36 GB.

Which GPUs can run Qwen3 Next 80B A3B Instruct?

No single consumer GPU has enough VRAM to run Qwen3 Next 80B A3B Instruct at Q4_K_M (49.2 GB). Multi-GPU or professional hardware is required.

Which devices can run Qwen3 Next 80B A3B Instruct?

52 devices with unified memory can run Qwen3 Next 80B A3B Instruct at Q4_K_M (49.2 GB), including ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB), GMKtec EVO-X2 (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
