# GemCod270M - Jade (gemma-270m-it-code v4.1.0)

![GemCod logo](./gemcod_logo_c.png)
                                                                                                                                
GemCod is a lightweight code generation model finetuned using SFT on the base gemma-270m-it model(https://huggingface.co/google/gemma-3-270m-it). It offers accurate and quick(ish) code snippet and long-form code generation in all major programming languages.
It's small size (270M parameters) allows it to run comfortably on laptop grade GPUs.

The Jade model serves as an upgrade from the previous Aquamarine model(https://huggingface.co/DireDreadlord/GemCod-codegen-270M), as it provides facilities for superior long-form code generation and explainability of generated snippets whilst keeping the inference time and space requirements roughly the same.

This model also offers rudimentary Q/A and subject matter expert capabilities on code related subjects.

**Estimated parameters:** ~270M

**Architecture:** Gemma3

**Intended use:** Code snippet and long-form code generation from natural language

## Training data
- Source: magicoder-glaive-code-instruct dataset (https://huggingface.co/datasets/DireDreadlord/magicoder-glaive-code-instruct)
- Rows: ~350,000 rows templated with a custom .jinja chat format
- Training: trained for 3,000 steps on an RTX 3050 (4GB VRAM)


## Usage

Install requirements:

```bash
pip install -r requirements.txt
pip install transformers datasets accelerate safetensors
```


## Usage (Hugging Face Hub)
You can load it directly from HuggingFace:

```python
from transformers import AutoTokenizer, AutoModelForCausalLM


tokenizer = AutoTokenizer.from_pretrained("DireDreadlord/GemCod-Jade-270M")
model = AutoModelForCausalLM.from_pretrained("DireDreadlord/GemCod-Jade-270M")
model.to(device)
model.eval()
model.resize_token_embeddings(len(tokenizer))


if tokenizer.pad_token is None:
    tokenizer.pad_token = tokenizer.eos_token

chat_template = """{% for message in messages %}{% if message['role'] == 'user' %}User: {{ message['content'] }}
{% elif message['role'] == 'assistant' %}Assistant: {{ message['content'] }}
{% endif %}{% endfor %}"""
tokenizer.chat_template = chat_template

def generate_code(prompt, max_tokens) -> str:
    messages = [
        {
            "role": "user",
            "content": prompt
        }
    ]
    
    formatted_prompt = tokenizer.apply_chat_template(
        messages,
        tokenize=False,
        add_generation_prompt=True 
    )

    
    inputs = tokenizer(formatted_prompt, return_tensors="pt").to(device)
    input_length = inputs["input_ids"].shape[1]
    
    with torch.no_grad():
        outputs = model.generate(
            **inputs,
            max_new_tokens=512,
            do_sample=False,
            num_beams=1,
            pad_token_id=tokenizer.eos_token_id,
            eos_token_id=tokenizer.eos_token_id,
            use_cache=False,
        )

    generated_tokens = outputs[0][input_length:]
    generated_text = tokenizer.decode(generated_tokens, skip_special_tokens=True)
    return generated_text


prompt = "WAP to train a sklearn model to predict the price of a house based on its size and location"
print("Prompt: ", prompt)

result = generate_code(prompt)
print(result)
```
