Instructions to use Qwen/Qwen2.5-72B-Instruct with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Qwen/Qwen2.5-72B-Instruct with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Qwen/Qwen2.5-72B-Instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-72B-Instruct")
model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2.5-72B-Instruct", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Hi, I'm using huggingface_hub InferenceClient for inference, but I always get an error today:

"Model too busy, unable to get response in less than 120 second(s)"

endless stream!

from huggingface_hub import InferenceClient

client = InferenceClient(api_key="YOUR_HF_TOKEN")

messages = [{"role": "system", "content": SYSTEM_PROMPT}]

stream = client.chat.completions.create(
    model="Qwen/Qwen2.5-72B-Instruct", 
    messages=messages, 

    temperature = 0.1,
    top_p = 0.2,
    presence_penalty = 0.6,
    frequency_penalty = 0.6,
    max_tokens=6144,

    stream=True
)

for chunk in stream:  # this infinity Loop !!!
    print(chunk.choices[0].delta.content)

Yes, I also encounter this situation.Maybe it decreases the number of GPUs?

For those asking about API access — I've been using Crazyrouter as a unified gateway. One API key, OpenAI SDK compatible. Works well for testing different models without managing multiple accounts.

The "model is too busy" error usually happens when the HF Inference API is overloaded. If you need reliable access, consider using a dedicated API endpoint instead.

I have been using Crazyrouter which routes to multiple backends — if one is busy, it can failover. Plus it is OpenAI SDK compatible, so integration is straightforward.
