	# Koa-AI v1 Code 3B

	Koa-AI-v1-Code-3B is an ultra-lightweight, high-efficiency 3B parameter model fine-tuned for code generation, multi-step agentic planning, and debugging tasks.

	Built on top of `mistralai/Ministral-3b-instruct` using Unsloth and QLoRA, it is optimized to run blazingly fast on consumer hardware, local edge devices, and laptop GPUs without sacrificing code reasoning capabilities.

	---

	## ⚡ Highlights

	* Base Model: `mistralai/Ministral-3b-instruct`
	* Dataset: Fine-tuned on multi-turn debugging and agentic coding trace data (`greghavens/fable-5-coding-and-debugging-traces`).
	* Efficiency: Lightweight 3B parameter size allows low-latency, real-time code completion in local IDE extensions (e.g., Continue, VS Code).
	* Extended Context Support: Native context window up to 128,000 tokens (SFT fine-tuned at a 2,048 sequence length cap).

	## 💻 Quickstart & Usage

	### Running with `transformers` (Python)

	```python
	import torch
	from transformers import AutoTokenizer, AutoModelForCausalLM

	model_id = "vamazing/Koa-AI-v1-Code-3B"

	tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
	model = AutoModelForCausalLM.from_pretrained(
	model_id,
	torch_dtype=torch.float16,
	device_map="auto",
	trust_remote_code=True
	)

	prompt = "Write a Python function to check if a number is prime and optimize it for speed."
	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(model.device)
	outputs = model.generate(**inputs, max_new_tokens=512, do_sample=True, temperature=0.7)

	print(tokenizer.decode(outputs[0], skip_special_tokens=True))
