- License: Apache 2.0
- Fine-tuning method: QLoRA (LoRA rank=32) via LLaMA-Factory
What does this model do?
Given a Python programming question in English, the model returns a structured JSON answer in Arabic, explaining the solution step by step.
How to Use
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model_id = "jana-ashraf-ai/python-assistant"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.float16,
device_map="auto"
)
system_prompt = """You are a Python expert assistant.
Answer the user's Python question in Arabic following the Output Schema.
Do not add any introduction or conclusion."""
question = "How do I reverse a list in Python?"
messages = [
{"role": "system", "content": system_prompt},
{"role": "user", "content": question}
]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training Data
Fine-tuned on a curated subset (1,000 samples) from iamtarun/python_code_instructions_18k_alpaca.
The answers were annotated and structured using GPT to produce Arabic explanations in a JSON schema format.
Train / Val split: 90% / 10%
Limitations
- The model is optimized for Python questions only.
- Answers are in Arabic — not suitable for English-only use cases.
- Small model size (1.5B) may struggle with very complex programming problems.
- Output quality depends on the question being clear and specific.
