How to run Qwen 3.8 without a GPU
Two different questions hide behind this one. If you mean the big Qwen 3.8 checkpoints, the answer is a hosted endpoint, no subscription required, and the numbers are below. If you mean Qwen 3.8 in general, there is a 27B in the same family that runs on a 16 GB card, and that is a better answer for most people. Both routes are here.
What is actually hosted
The cloud catalog carries two Qwen 3.8 entries, and every plan and every credit pack reaches both of them:
| Qwen 3.8 Max | Qwen 3.8 A95B | |
|---|---|---|
| Model id | Qwen/Qwen3.8-Max | Qwen/Qwen3.8-2.4T-A95B |
| Plan | Every plan and every credit pack | Every plan and every credit pack |
| Credits per input token | 0.165 | 0.2 |
| Credits per output token | 0.4951 | 0.6 |
| Image input | No | No |
| Thinking | On by default, can be switched off | On by default, cannot be switched off |
| Tool calls | Native | Native |
One credit is $0.00001 of wholesale inference cost. The difference between those two is smaller than the names suggest and the thinking switch is the part that matters, which is why it has its own page.
Which plan, and what it buys
Every plan and every credit pack reaches the whole chat catalog, so a bigger plan buys a bigger budget and nothing else. A 5 EUR credit pack is 165,000 credits and needs no subscription at all. The Hosted plan is 19 EUR a month for 900,000 credits, Pro is 49 EUR for 2,350,000 and Max is 99 EUR for 5,000,000.
Spent entirely on output tokens, that works out to roughly:
| Budget | Qwen 3.8 Max | Qwen 3.8 A95B |
|---|---|---|
| 5 EUR pack, 165,000 credits | 333,000 output tokens | 275,000 output tokens |
| Hosted, 900,000 credits | 1.8 million | 1.5 million |
| Pro, 2,350,000 credits | 4.7 million | 3.9 million |
| Max, 5,000,000 credits | 10.1 million | 8.3 million |
Those are output tokens only. Input tokens come out of the same wallet, so a long context chat lands below the figure in the row.
What else is in the same picker
The other 36 chat models sit next to the two Qwen 3.8 entries rather than behind a plan, and most of them are far cheaper per token. A few worth knowing by name:
- GLM 5.3 Flash, which takes images, reasons on every turn and holds a 1M context, at 0.015 credits per input token and 0.05 per output token
- Kimi K3, the 2.8 trillion parameter multimodal reasoner, at 0.285 in and 1.425 out
- DeepSeek V3.2 at 0.026 in and 0.038 out, with a think toggle
- Gemma 4 26B with image input at 0.007 in and 0.034 out
- gpt-oss 120B at 0.0037 in and 0.017 out
- Ling 3.0 flash at 0.006 in and 0.018 out
If what you wanted from Qwen 3.8 was a strong reasoner without buying a card, GLM 5.3 Flash gets you most of the way there for a tenth of the token price, and it reads pictures, which neither Qwen 3.8 entry does.
The API route
- Sign in at lu-labs.ai and go to Settings > Cloud API keys.
- Create a key. It carries an
lu_prefix and is shown once, so copy it before the dialog closes. - Point your client at base URL
https://lu-labs.ai/api/inference/v1with the OpenAI chat completions shape.
curl https://lu-labs.ai/api/inference/v1/chat/completions \
-H "Authorization: Bearer $LU_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "Qwen/Qwen3.8-Max",
"messages": [
{"role": "user", "content": "Explain this stack trace and name the likely cause."}
]
}'
SillyTavern, Aider, LibreChat and anything else that takes a base URL, a key and a model string work against the same endpoint.
The other answer: run the 27B at home
The same Qwen 3.8 wave shipped a 27B dense checkpoint, and unlike the big two it is Apache 2.0 and it fits on hardware people actually own. Real numbers from our own setup guide:
| Quant | Size | Practical home |
|---|---|---|
| UD-Q3_K_XL | 13.4 GB | 16 GB cards |
| IQ4_XS | 15.7 GB | 16 GB cards, the last one that fits whole |
| Q4_K_M | 17.1 GB | 24 GB cards, the sweet spot |
| Q6_K | 22.9 GB | 24 GB, barely, or 32 GB |
It is a native vision language model, so a 0.9 GB mmproj file gets you image input the hosted Qwen 3.8 entries do not have. Context is 262,144 native. The full walkthrough with the KV cache math and the chat template trap is in how to run Qwen 3.8 27B locally, and there is a mirror of it at lu-labs.ai.
Our free desktop app for Windows and Linux is one way to run it, and it has a Cloud switch on the same account, so the local 27B and the hosted models sit in one picker. That is the setup we actually use: the 27B for the everyday work that stays on the machine, the switch for the prompts that outgrow it.
