# Kexer models

Kexer models is a collection of fine-tuned open-source generative text models fine-tuned on Kotlin Exercices dataset. 
This is a repository for fine-tuned CodeLlama-7b model in the Hugging Face Transformers format.

# Model use

```python
  from transformers import AutoModelForCausalLM, AutoTokenizer

  # Load pre-trained model and tokenizer
  model_name = 'JetBrains/CodeLlama-7B-Kexer'  # Replace with the desired model name
  tokenizer = AutoTokenizer.from_pretrained(model_name)
  model = AutoModelForCausalLM.from_pretrained(model_name).cuda()

  # Encode input text
  input_text = """This function takes an integer n and returns factorial of a number:
  fun factorial(n: Int): Int {"""
  input_ids = tokenizer.encode(input_text, return_tensors='pt').to('cuda')

  # Generate text
  output = model.generate(input_ids, max_length=150, num_return_sequences=1, no_repeat_ngram_size=2, early_stopping=True)

  # Decode and print the generated text
  generated_text = tokenizer.decode(output[0], skip_special_tokens=True)
  print(generated_text)
```

# Training setup

The model was trained on one A100 GPU with following hyperparameters:

|         **Hyperparameter**           |             **Value**              |
|:---------------------------:|:----------------------------------------:|
|           `warmup`            |           10%            |
|        `max_lr`        |          1e-4          |
|        `scheduler`        |          linear          |
|        `total_batch_size`        |          256 (~130K tokens per step)          |


# Fine-tuning data

For this model we used 15K exmaples of Kotlin Exercices dataset {TODO: link!}. For more information about the dataset follow th link.

# Evaluation 

To evaluate we used Kotlin Humaneval (more infromation here)

Fine-tuned model:
