Thought & Code:

Quick Start

Using Transformers (Python)

python

# Method 1: Pipeline (Recommended for beginners)
from transformers import pipeline

pipe = pipeline("text-generation", model="amkyawdev/amk-coder-v2")
messages = [
    {"role": "user", "content": "Python function တစ်ခုရေးပါ။ list comprehension နဲ့ sorting လုပ်ပေးပါ။"}
]
result = pipe(messages, max_new_tokens=512, temperature=0.2)
print(result[0]['generated_text'])

# Method 2: Direct Model Loading
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

tokenizer = AutoTokenizer.from_pretrained("amkyawdev/amk-coder-v2")
model = AutoModelForCausalLM.from_pretrained(
    "amkyawdev/amk-coder-v2",
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

messages = [
    {"role": "system", "content": "You are a helpful coding assistant."},
    {"role": "user", "content": "Write a Python function to reverse a string"}
]

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

outputs = model.generate(inputs, max_new_tokens=512, temperature=0.2)
response = tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True)
print(response)

Using vLLM (Production)

bash

# Install vLLM
pip install vllm

# Start server
vllm serve "amkyawdev/amk-coder-v2" --tensor-parallel-size 1

# API call
curl -X POST "http://localhost:8000/v1/chat/completions" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amkyawdev/amk-coder-v2",
    "messages": [
      {"role": "user", "content": "Hello, write Python code"}
    ],
    "max_tokens": 512,
    "temperature": 0.2
  }'

Using SGLang

bash

# Install SGLang
pip install sglang

# Start server
python -m sglang.launch_server --model-path "amkyawdev/amk-coder-v2" --port 30000

# API call
curl -X POST "http://localhost:30000/v1/chat/completions" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "amkyawdev/amk-coder-v2",
    "messages": [{"role": "user", "content": "Write a hello world in Python"}]
  }'

Usage Examples

🇲🇲 Myanmar Prompts

python

messages = [
    {"role": "user", "content": "Python function တစ်ခုရေးပါ။ ဂဏန်းတွေကို sorting လုပ်ပေးပါ။"}
]
# Output: def sort_numbers(numbers): return sorted(numbers)

🇬🇧 English Prompts

python

messages = [
    {"role": "user", "content": "Explain this code:\nfor i in range(10):\n    print(i)"}
]
# Output: This is a for loop that prints numbers 0 to 9

🐛 Debugging

python

messages = [
    {"role": "user", "content": "Fix this Python code:\nprint('Hello' + 5)"}
]
# Output: TypeError fix suggestion with corrected code

API Deployment

⚠️ Limitations

Context Length - Maximum 32,768 tokens
Code Quality - May generate incorrect code; verify outputs
Myanmar Unicode - Best results with proper Zawgyi-to-Unicode conversion
Domain Knowledge - Limited to common programming languages
Safety - May produce harmful content; use responsible AI practices
