LaboAI-0.4.0-3B

LaboAI-0.4.0-3B is a 3B-parameter code model fine-tuned for Android / Kotlin / Jetpack Compose development. It is built on top of Qwen2.5-Coder-3B-Instruct using QLoRA with Unsloth, and the LoRA weights are merged into the released model.

Model details


Developer	LaboAI
Base model	Qwen/Qwen2.5-Coder-3B-Instruct
Parameters	~3B
Fine-tuning method	QLoRA (4-bit base, LoRA r=32, alpha=64)
Context used in training	1024 tokens
Languages	Kotlin, Java, general code; English and Spanish prompts
Available formats	Merged safetensors, GGUF `q4_k_m`

Intended use

Generating and explaining Kotlin code for Android apps
Jetpack Compose UI snippets, ViewModels, state handling, Room, Retrofit, coroutines
Fixing and refactoring small to medium Kotlin snippets
Local inference on modest hardware via the GGUF build (llama.cpp, Ollama, LM Studio)

Prompt format

The model was trained with a plain instruction/response template (not the Qwen chat template), so for best results use:

### Instruction:
{your request}

### Response:

How to use

Transformers

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

repo = "LaboAI/LaboAI-0.4.0-3B"
tokenizer = AutoTokenizer.from_pretrained(repo)
model = AutoModelForCausalLM.from_pretrained(
    repo, torch_dtype=torch.float16, device_map="auto"
)

prompt = (
    "### Instruction:\n"
    "Write a Jetpack Compose screen with a counter and a button to increment it.\n\n"
    "### Response:\n"
)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=512, temperature=0.2, do_sample=True)
print(tokenizer.decode(out[0], skip_special_tokens=True))

llama.cpp / GGUF

llama-cli -m LaboAI-0.4.0-3B-Q4_K_M.gguf -c 2048 --temp 0.2 \
  -p "### Instruction:\nCreate a Room DAO for a Note entity.\n\n### Response:\n"

Training data

The training mix was filtered for Android/Kotlin/Jetpack content (keyword filter on the text fields) and formatted into the instruction/response template above:

Dataset	Notes
giggiovpg/ornith-android-instruct	Android instruct data
giggiovpg/android-kotlin-compose-compiler-verified	Compose code verified by compiler
microsoft/NextCoderDataset	Kotlin subset, capped at 10,000
glaiveai/glaive-code-assistant-v3	Android/Kotlin subset, capped at 6,000
theblackcat102/evol-codealpaca-v1	Android/Kotlin subset
sahil2801/CodeAlpaca-20k	Android/Kotlin subset
genqa/GenQA (code split)	Android/Kotlin subset, capped at 4,000

Examples with empty or near-empty text were removed, and the final dataset was shuffled (seed 42).

Training procedure

Hyperparameter	Value
LoRA rank / alpha / dropout	32 / 64 / 0
Target modules	q, k, v, o, gate, up, down projections
Max sequence length	1024
Per-device batch size	2
Gradient accumulation	4 (effective batch 8)
Steps	4,500
Warmup steps	225
Learning rate	1e-4 (cosine)
Weight decay	0.01
Optimizer	AdamW 8-bit
Precision	fp16 (T4)
Hardware	1x NVIDIA T4 (Kaggle)
Framework	Unsloth + TRL SFTTrainer

Limitations and risks

It is a small 3B model: it can produce code that does not compile, uses deprecated or non-existent APIs, or contains subtle bugs. Always review and test the output.
Trained with a 1024-token context, so very long files or multi-file projects may degrade quality.
The keyword-based filtering may have let in some off-topic examples.
Android and Compose APIs change quickly; the model may not know the latest library versions.
Not evaluated on formal benchmarks yet; no quantitative results are claimed.

This model is derived from Qwen2.5-Coder-3B-Instruct and inherits its license (Qwen Research License). Please check the base model's license for terms of use, especially for commercial use. The training datasets have their own licenses, which you should also review.
