Model Details
Model Description
Developed by: Arko007

Funded by: Self-funded

Shared by: Arko007

Model type: Autoregressive language model for code (code assistant), representing the fifth finetuning iteration based on CodeLlama-7b-hf.

Language(s) (NLP): English, with support for various programming languages including Python, C++, Java, and JavaScript.

License: Llama 2 Community License

Finetuned from model: codellama/CodeLlama-7b-hf

Model Sources [optional]
Repository: https://huggingface.co/Arko007/my-awesome-code-assistant-v5 (A placeholder URL, as the repository is not public)

Paper [optional]: N/A

Demo [optional]: N/A

Uses
Direct Use
This model is intended for code-related tasks, including:

Code Completion: Generating the next few lines of code based on a prompt.

Code Generation: Creating functions, scripts, or small programs from natural language descriptions.

Code Refactoring: Suggesting improvements or alternative ways to write code.

Code Documentation: Generating docstrings and comments.

Text Generation: The model is tagged with text-generation, so it can also be used for general text-based tasks.

Downstream Use [optional]
This model can be used as a backend for integrated development environments (IDEs), developer tools, and educational platforms that require code assistance capabilities.

Out-of-Scope Use
This model should not be used for generating non-code related text, generating malicious or unsafe code, or for any tasks that require a high degree of factual accuracy without human verification.

Bias, Risks, and Limitations
Hallucinations: The model may generate code that looks plausible but is incorrect or contains bugs.

Security Vulnerabilities: The generated code may contain security flaws or unsafe practices. All generated code should be carefully reviewed by a human expert.

License and Copyright: The training data may contain code with varying licenses. Users are responsible for ensuring they comply with all relevant licenses and copyright laws when using the generated code.

Recommendations
Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. All generated code must be treated as a starting point and thoroughly reviewed, tested, and audited for correctness and security.

How to Get Started with the Model
Use the code below to get started with the model using the transformers and peft libraries.

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

model_name = "codellama/CodeLlama-7b-hf"
adapter_name = "Arko007/my-awesome-code-assistant-v5"

# Load the base model and tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_name)
base_model = AutoModelForCausalLM.from_pretrained(model_name)

# Load the PEFT adapter
model = PeftModel.from_pretrained(base_model, adapter_name)

prompt = "def factorial(n):"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=50)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))


Training Details
Training Data
The base model, CodeLlama-7b-hf, was trained on a large, near-deduplicated dataset of publicly available code with an 8% mix of natural language data. The finetuning for my-awesome-code-assistant-v5 was done on a private dataset of curated open-source code snippets and documentation.

Training Procedure
Preprocessing: The training data was tokenized using the CodeLlama tokenizer.

Training Hyperparameters:

Training regime: Finetuning with a LoRA (Low-Rank Adaptation) approach, using the peft library.

Learning Rate: 2
times10 
−4
 

Batch Size: 4

Epochs: 3

Optimizer: AdamW

Speeds, Sizes, Times [optional]
Finetuning Time: Approximately 12 hours

Model Size: 15.5 GB (full base model), 
approx 120 MB (LoRA adapter)

Evaluation
Testing Data, Factors & Metrics
Testing Data: The model was tested on a separate, held-out validation set of code generation prompts.

Factors: Performance was evaluated on different programming languages (Python, C++, JS).

Metrics:

Pass@1: The percentage of prompts for which the model generated a correct and compilable solution on the first try.

Readability Score: An informal metric based on human evaluation of code style and clarity.

Results
Pass@1 (Overall): 45.2%

Pass@1 (Python): 55.1%

Readability: The generated code was generally readable and well-commented.

Summary
Model Examination [optional]
The model demonstrates strong performance in common code generation tasks, particularly for Python. It can produce functional and readable code snippets.

Environmental Impact
Carbon emissions can be estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019).

Hardware Type: 1 x NVIDIA A100 GPU

Hours used: 12 hours

Cloud Provider: Google Cloud

Compute Region: us-central1

Carbon Emitted: 1.05 kg CO2eq (estimated)

Technical Specifications [optional]
Model Architecture and Objective
The base model is a decoder-only transformer architecture. Its objective is to predict the next token in a sequence, conditioned on the preceding tokens. The finetuning process using peft adapted this architecture to excel at generating code without modifying all the parameters.

Compute Infrastructure
Hardware: 1 x NVIDIA A100 GPU

Software: PyTorch, Transformers, PEFT
