How to Use
1. Install and import the necessary libraries, such as transformers and torch.
2. Load the model and tokenizer from Hugging Face: `model = AutoModelForCausalLM.from_pretrained(model_name)` and `tokenizer = AutoTokenizer.from_pretrained(model_name)`.
3. Prepare your input prompt, such as the requirements for an algorithm.
4. Use `tokenizer.apply_chat_template` to process the input message and generate the model input.
5. Pass the model input to the model, setting generation parameters such as `max_new_tokens=512`.
6. Call the model's `generate` method to produce code.
7. Use `tokenizer.batch_decode` to convert the generated code IDs into text format.
