Question 1

How much VRAM does Qwen3-Coder-Next need?

Accepted Answer

Qwen3-Coder-Next (79.7B) requires approximately 178.0861421585083 GB of VRAM at full precision (FP16), 89 GB at 8-bit quantization (Q8), and 44.5 GB at 4-bit quantization (Q4). The actual VRAM usage may be slightly higher due to KV cache and runtime overhead.

Question 2

What GPUs can run Qwen3-Coder-Next?

Accepted Answer

We have 5 compatible GPUs indexed for Qwen3-Coder-Next, including MI300X, B200, B100, MI325X, MI350X. Compatibility is determined by whether the GPU's VRAM can fit the model's memory footprint, potentially using quantization to reduce memory usage.

Question 3

What is the cheapest GPU to run Qwen3-Coder-Next?

Accepted Answer

The cheapest GPU to run Qwen3-Coder-Next in the cloud is the MI300X at $1.99/hr. Other affordable options include B200 ($5.49/hr). Prices reflect the lowest on-demand rate across cloud providers.

Question 4

Can Qwen3-Coder-Next run on consumer hardware?

Accepted Answer

Qwen3-Coder-Next requires approximately 178.0861421585083 GB of VRAM at FP16, and even with 4-bit quantization (Q4) it needs about 44.5 GB. This exceeds the 24 GB available on the highest-end consumer GPU (RTX 4090), so Qwen3-Coder-Next requires datacenter or cloud GPUs.

Question 5

What quantization options are available for Qwen3-Coder-Next?

Accepted Answer

Qwen3-Coder-Next supports the following quantization levels: FP16 (full precision): ~178.0861421585083 GB, Q8 (8-bit): ~89 GB, Q6 (6-bit): ~66.8 GB, Q4 (4-bit): ~44.5 GB. Lower quantization reduces VRAM usage at the cost of some quality loss. Q8 offers a good balance between quality and memory savings, while Q4 provides maximum compression. As a Mixture of Experts (MoE) model with 512 experts (10 active), Qwen3-Coder-Next has a larger total weight size but only activates a subset of parameters per token, which can affect effective memory usage during inference.
