📖 Overview

This specialized CodeT5 model has been fine-tuned for C++ code completion tasks.
It excels at understanding C++ syntax and common programming patterns to provide intelligent code suggestions as you type.

---

✨ Key Features

• 🔹 Context-aware completions for C++ functions, classes, and control structures
• 🔹 Handles complex C++ syntax including templates, STL, and modern C++ features
• 🔹 Trained on competitive programming solutions from high-quality Codeforces submissions
• 🔹 Low latency suitable for real-time editor integration

⚙️ Installation & Usage

🔧 Direct Integration with HuggingFace Transformers

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer

# Load model and tokenizer
model = AutoModelForSeq2SeqLM.from_pretrained("outlander23/codelander")
tokenizer = AutoTokenizer.from_pretrained("outlander23/codelander")

# Generate completion
def get_completion(code_prefix, max_new_tokens=100):
    inputs = tokenizer(f"complete C++ code: {code_prefix}", return_tensors="pt")
    outputs = model.generate(
        inputs.input_ids,
        max_new_tokens=max_new_tokens,
        temperature=0.7,
        top_p=0.9,
        do_sample=True
    )
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

💻 Example Completions

✅ Example 1: Factorial Function

Input:

int factorial(int n) {
    if (n <= 1) {
        return 1;
    } else {

Completion:

        return n * factorial(n - 1);
    }
}
