Qwen3.6-35B-A3B GPU requirements
Qwen3.6-35B-A3B has 36B parameters. To serve it, plan for about 86 GB of GPU memory in 16-bit, 43 GB in 8-bit or 22 GB in 4-bit, including about 20% for the KV cache and activations.
It is a mixture of experts: 256 experts, 8 of them active for each token. All of them stay in GPU memory, so plan memory for all 36B parameters.
What it takes to serve it
GPU memory to run it for inference, with the smallest GPU setup that holds it and the lowest price on Arrakis right now.
| Precision | Memory and the smallest setup |
|---|---|
| 16-bit | 86 GB: one RTX PRO 6000, from $1.90 per GPU-hour |
| 8-bit | 43 GB: one L40S, RTX 6000 Ada or RTX A6000, L40S from $0.44 per GPU-hour |
| 4-bit | 22 GB: one RTX 4090 or RTX 3090, RTX 3090 from $0.19 per GPU-hour |
What it takes to fine-tune it
QLoRA trains adapters on a 4-bit frozen model, LoRA on a 16-bit one, and full fine-tuning updates every weight. Figures are before activations, which grow with batch size and sequence length.
| Method | Memory and the smallest setup |
|---|---|
| QLoRA | 25 GB: one RTX 5090, from $0.58 per GPU-hour |
| LoRA | 86 GB: one RTX PRO 6000, from $1.90 per GPU-hour |
| Full fine-tuning | 575 GB: 8 × H100, from $16.56 per hour for all 8 |

Deploy it on Arrakis
Open Models in the console, choose vLLM, SGLang or llama.cpp, and rent a GPU it fits on. You get an OpenAI-compatible endpoint with its own API key, and root SSH to the machine. Or run it yourself on any machine with enough GPU memory:
vllm serve Qwen/Qwen3.6-35B-A3B --tensor-parallel-size 1Questions
