How to access Qwen 2.5
1. Zero‑setup: Qwen Chat web interface
The fastest route is the free web front‑end at chat.qwen.ai (international) or chat.qwenlm.ai (China). It is a fork of Open‑WebUI, supports model‑selection, system prompts and file uploads, and does not require a Chinese phone number for signup.
Steps:
- Create or sign in with an Alibaba Cloud ID.
- Click the model selector → pick Qwen 2.5‑7B‑Instruct, Qwen 2.5‑VL‑72B‑Instruct or QwQ‑32B.
- Adjust temperature / max tokens if needed; hit Run.
Latency is ~3 s/req for 7 B and ~12 s/req for 72 B from Europe (observed).
2. Alibaba Cloud Model Studio & DashScope APIs
If you prefer managed inference, follow the Model Studio onboarding:
- Create an Alibaba Cloud account and enable “Model Studio” in your console.
- Navigate to Models ► Qwen ► qwen‑max‑2025‑01‑25 and click Create API.
- Copy the auto‑generated AccessKey ID and Secret, then install the SDK:
bashpip install alibabacloud_aiserviceAlibaba exposes two endpoints:
| Endpoint | Format | Billing | Strengths |
|---|---|---|---|
| OpenAI‑compatible | /v1/chat/completions | Pay‑as‑you‑go USD 0.7 / 1M tokens (7 B) | Drop‑in with OpenAI SDKs |
| DashScope | dashscope.api.Chat | Same pricing; free 50 k tokens | Fine‑grained control, tools calling, streaming chunks |
Example (Python):
import alibabacloud_aiservice as ai
client = ai.Client(access_key_id, access_key_secret, region_id="ap-southeast-1")
resp = client.generate(
model="qwen-max-2025-01-25",
prompt="Summarize the latest semiconductor export regulations from the US (2024‑2025).",
top_p=0.9, temperature=0.3, max_tokens=512
)
print(resp.text)SDKs exist for Java, Go, JS, PHP. Traffic stays within Alibaba’s Frankfurt PoP for EU users.The Max endpoint taps the 72 B checkpoint with dynamic MoE routing, delivering approx. 7 tokens / s on the public endpoint and billing by output tokens.
3. Self‑host with Ollama, Docker or Transformers
The QwenLM/Qwen2.5 GitHub repo publishes HF safetensors, tokenizer and configuration.
bash# one‑liner with Ollama (CPU/GPU)
ollama run qwen2.5:7b
For GPU clusters, pull the NGC container qwen‑2.5‑7b‑instruct (CUDA 12 + Python 3.10). The Docker image bundles Flash‑Attention 2 and LoRA scaffolding for finetuning.
Hardware recommendations
| Model | vRAM (fp16) | vRAM (int4/ggml) | Notes |
|---|---|---|---|
| 1.5 B | 4 GB | ‑ | Raspberry Pi 5 compatible |
| 7 B | 24 GB | 8 GB | RTX 4090 hits 115 t/s |
| 72 B | 8×80 GB A100 | 3×48 GB with quantization | Use deepspeed‑ZeRO‑3 |
4. Hugging Face & ModelScope
All base and instruct checkpoints, plus the multimodal VL and Omni branches, are mirrored to huggingface.co/Qwen/ and modelscope.cn/models/Qwen/ . Model cards include SHA256 sums, license (Apache 2.0 with Responsible‑AI addendum), and evaluation scripts. Chinese developers behind the Great Firewall can leverage ModelScope’s object‑storage acceleration.
