	# Model description

	This is a repository for the CodeLlama-7b model fine-tuned on the [KStack-clean](https://huggingface.co/datasets/JetBrains/KStack-clean) dataset with rule-based filtering, in the Hugging Face Transformers format. KStack-clean is a small subset of [KStack](https://huggingface.co/datasets/JetBrains/KStack), the largest collection of permissively licensed Kotlin code, automatically filtered to include files that have the highest "educational value for learning algorithms in Kotlin".

	# How to use

	```python
	from transformers import AutoModelForCausalLM, AutoTokenizer

	# Load pre-trained model and tokenizer
	model_name = 'JetBrains/CodeLlama-7B-KStack-clean'
	tokenizer = AutoTokenizer.from_pretrained(model_name)
	model = AutoModelForCausalLM.from_pretrained(model_name).to('cuda')

	# Create and encode input
	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
	output = model.generate(
	input_ids, max_length=60, num_return_sequences=1,
	pad_token_id=tokenizer.eos_token_id
	)

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

	As with the base model, we can use FIM. To do this, the following format must be used:
	```
	'<PRE> ' + prefix + ' <SUF> ' + suffix + ' <MID>'
	```

	# Training setup

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

	\| Hyperparameter \| Value \|
	\|:---------------------------:\|:----------------------------------------:\|
	\| `warmup` \| 100 steps \|
	\| `max_lr` \| 5e-5 \|
	\| `scheduler` \| linear \|
	\| `total_batch_size` \| 32 (~30K tokens per step) \|
	\| `num_epochs` \| 2 \|

	More details about fine-tuning can be found in the technical report (coming soon!).

	# Fine-tuning data

	For tuning the model, we used 25K exmaples from the [KStack-clean](https://huggingface.co/datasets/JetBrains/KStack-clean) dataset, selected from the larger [KStack](https://huggingface.co/datasets/JetBrains/KStack) dataset according to educational value for learning algorithms. In total, the dataset contains about 23M tokens.

	# Evaluation

	For evaluation, we used the [Kotlin HumanEval](https://huggingface.co/datasets/JetBrains/Kotlin_HumanEval) dataset, which contains all 161 tasks from HumanEval translated into Kotlin by human experts. You can find more details about the pre-processing necessary to obtain our results, including the code for running, on the [datasets's page](https://huggingface.co/datasets/JetBrains/Kotlin_HumanEval).

	Here are the results of our evaluation:

	\| Model name \| Kotlin HumanEval Pass Rate \|
	\|:---------------------------:\|:----------------------------------------:\|
	\| `CodeLlama-7B` \| 26.89 \|
	\| `CodeLlama-7B-KStack-clean` \| 37.89 \|

	# Ethical Considerations and Limitations

	CodeLlama-7B-KStack-clean is a new technology that carries risks with use. The testing conducted to date has not covered, nor could it cover all scenarios. For these reasons, as with all LLMs, CodeLlama-7B-KStack-clean's potential outputs cannot be predicted in advance, and the model may in some instances produce inaccurate or objectionable responses to user prompts. The model was fine-tuned on a specific data format (Kotlin tasks), and deviation from this format can also lead to inaccurate or undesirable responses to user queries. Therefore, before deploying any applications of CodeLlama-7B-KStack-clean, developers should perform safety testing and tuning tailored to their specific applications of the model.
