Usage

Installation

pip install transformers torch

Basic Code Generation

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "your-username/sheikh-2.5-coder"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

prompt = "Write a function to sort an array using quicksort:"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    **inputs,
    max_new_tokens=200,
    temperature=0.1,
    do_sample=True,
    top_p=0.95
)
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(result)

Chat Interface

messages = [
    {"role": "user", "content": "Create a Python class for managing a student database:"}
]

inputs = tokenizer.apply_chat_template(
    messages, 
    add_generation_prompt=True, 
    return_tensors="pt"
).to(model.device)

outputs = model.generate(
    inputs,
    max_new_tokens=300,
    temperature=0.1,
    do_sample=True,
    top_p=0.95
)

response = tokenizer.decode(
    outputs[0][len(inputs[0]):], 
    skip_special_tokens=True
)
print(response)

Quantized Inference

8-bit Quantization

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    load_in_8bit=True,
    device_map="auto"
)

4-bit Quantization

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    load_in_4bit=True,
    device_map="auto"
)

Performance

Benchmarks

The model achieves strong performance on code generation benchmarks:

• HumanEval: 51% pass@1
• MBPP: 57% pass@1
• MultiPL-E: Competitive performance across languages

Efficiency Metrics

• Memory Usage: ~10.8GB (full precision), ~2GB (4-bit quantized)
• Inference Speed: ~1.7 seconds per generation
• Throughput: Optimized for real-time applications

Deployment

On-Device Deployment

The model is optimized for mobile and edge deployment:

1. CPU-only: Full functionality on modern CPUs
2. 4-bit Quantized: Maximum efficiency for edge devices
3. 8-bit Quantized: Balance of performance and memory usage

Hardware Requirements

• Minimum RAM: 4GB (4-bit), 8GB (8-bit), 16GB (full precision)
• CPU: Modern multi-core processor
• GPU: Optional, for faster inference

Limitations

1. Context Window: 32K tokens (sufficient for most coding tasks)
2. Training Data: Performance varies by programming language
3. Code Quality: Generated code may require review and testing
4. Deployment: Requires proper quantization for optimal mobile performance

Ethical Considerations

• Generated code should be reviewed before use in production
• The model may produce code with security vulnerabilities
• Users are responsible for ensuring code compliance with their standards
• Consider safety implications when using for automated code generation
