| ============================== | |
| MANDATORY | |
| - Before submitting, ensure the following variables are defined in your environment configuration: | |
| API_BASE_URL The API endpoint for the LLM. | |
| MODEL_NAME The model identifier to use for inference. | |
| HF_TOKEN Your Hugging Face / API key. | |
| - The inference script must be named `inference.py` and placed in the root directory of the project | |
| - Participants must use OpenAI Client for all LLM calls using above variables | |
