Truss Python: Qwen3-4B Specialized Coding Assistant

Truss Python is a specialized fine-tuned version of Qwen3-4B-Instruct-2507, optimized for generating clean, professional, and robust Python code. By focusing on high-quality seed prompts involving standard libraries, asynchronous programming, and data structures, this model prioritizes type safety, documentation, and modern Pythonic patterns.

🚀 Model Details

Base Model: Qwen/Qwen3-4B-Instruct-2507
Architecture: Qwen3ForCausalLM
Fine-Tuning Method: LoRA (Low-Rank Adaptation)
Quantization: Q4_K_M (GGUF)
File Size: ~2.5 GB
License: Apache 2.0 (Inherited from Qwen3)

✨ Key Features

Professional Structure: Consistently generates code with Google-style docstrings and comprehensive type hints.
Modern Syntax: Proficient in Python 3.10+ features like match-case structural pattern matching.
Robust Error Handling: Prioritizes try/except blocks and resource management (e.g., async with, contextlib).
Standard Library Focus: Expert-level knowledge of asyncio, threading, csv, functools, and pandas.

💻 Usage with Ollama

This model is optimized for local deployment using Ollama.

1. Local Import (Using GGUF)

If you have downloaded the .gguf file:

Create a Modelfile:

FROM ./truss-qwen3-python-lora.gguf
PARAMETER temperature 0.2
SYSTEM "You are an expert Python developer. Provide clean, efficient, and well-documented code."

Create the model in your terminal:

ollama create truss-python -f Modelfile

Run the model:
```
ollama run truss-python
```

🧪 Example Prompts

Task	Prompt
Algorithms	"Write a binary search function with type hints and no built-in libraries."
Decorators	"Create a `@timer` decorator using `functools.wraps` and `time.perf_counter`."
Async I/O	"Fetch data from 3 URLs concurrently using `aiohttp` and `asyncio.gather`."
Data Science	"Optimize a pandas merge for 1M+ rows using specific dtypes."

⚙️ Technical Specifications
