  "textContent": "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.\n\nTo fix this and successfully complete your exam, follow these steps:\n\n### 1. Update the Base URL\n\nYou must replace the deprecated URL with the new “Router” address in your configuration.\n\n  * **Old URL:** `https://api-inference.huggingface.co/...`\n\n  * **New URL:** `https://router.huggingface.co/hf-inference/v1`\n\n\n\n\n### 2. Upgrade the Model Version\n\nSince 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.\n\n### 3. Implementation Example (Python)\n\nIf you are using the OpenAI SDK or a similar client to connect to Hugging Face, update your initialization as follows:\n\nPython\n\n\n    from openai import OpenAI\n\n    client = OpenAI(\n        base_url=\"https://router.huggingface.co/hf-inference/v1\", # Update this line\n        api_key=\"YOUR_HF_TOKEN\"\n    )\n\n    # Use the latest model version\n    response = client.chat.completions.create(\n        model=\"Qwen/Qwen3.5-Coder-32B-Instruct\",\n        messages=[{\"role\": \"user\", \"content\": \"Explain your fine-tuning process.\"}]\n    )\n\n\n\n* * *\n\n**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.",
