The error you are seeing ( **410 Gone** ) is not a bug in your code logic, but a result of **Hugging Face’s recent infrastructure migration**. The old inference endpoint has been decommissioned in favor of a new routing system.

To fix this and successfully complete your exam, follow these steps:

### 1. Update the Base URL

You must replace the deprecated URL with the new “Router” address in your configuration.

- **Old URL:** `https://api-inference.huggingface.co/...`

- **New URL:** `https://router.huggingface.co/hf-inference/v1`

### 2. Upgrade the Model Version

Since you are currently pointing to **Qwen 2.5** , you should take this opportunity to upgrade to the latest iteration. **Qwen 3.5-Coder** (or the most recent version available on the Hub) offers significantly better reasoning and syntax handling for LLM fine-tuning tasks.

### 3. Implementation Example (Python)

If you are using the OpenAI SDK or a similar client to connect to Hugging Face, update your initialization as follows:

Python

```auto
from openai import OpenAI

client = OpenAI(
    base_url="https://router.huggingface.co/hf-inference/v1", # Update this line
    api_key="YOUR_HF_TOKEN"
)

# Use the latest model version
response = client.chat.completions.create(
    model="Qwen/Qwen3.5-Coder-32B-Instruct", 
    messages=[{"role": "user", "content": "Explain your fine-tuning process."}]
)

```

**Note:** Once you switch to the `router.huggingface.co` endpoint, the connection error will disappear, allowing the automated grader to verify your code and issue your certificate.
