🧠 DQN Code v0.2

A 1.5B Python Specialist

DQN Code v0.2 is a lightweight coding-focused model built on Qwen2.5-1.5B-Instruct and fine-tuned specifically for high-quality Python generation.

This release focuses on algorithmic correctness, structured implementation, and clean function completion.

🚀 Highlights

🔹 1.5B parameters
🔹 LoRA fine-tuned
🔹 Python-specialized
🔹 Optimized for deterministic completion
🔹 Designed to run locally on 8GB systems

📊 Benchmark Performance

HumanEval (0-shot, temperature=0.0)
Evaluated using mlx_lm.

Model	Parameters	HumanEval pass@1
Qwen2.5-1.5B-Instruct (official)	1.5B	~37.8%
MistralAI Mistral 7B	7B	~30.5%
Google Gemma 2 9B (as on llmstats.com)	9B	~40.2%
DQN Code v0.2	1.5B	49.39%

Evaluation settings:

0-shot

Temperature = 0.0

No few-shot prompting

Full 164 HumanEval tasks

This represents a +11.6% absolute improvement over the base Instruct model.

🎯 Design Philosophy

Instead of scaling parameters, DQN Code focuses on:

High-quality distilled supervision
Python-heavy training distribution
Clean function-style completions
Reduced conversational overhead
Local inference efficiency

Small models benefit heavily from specialization.
This release demonstrates how targeted fine-tuning can significantly improve coding performance without increasing model size.

🔧 Training Details

Base: Qwen2.5-1.5B-Instruct
Fine-tune type: LoRA
Effective batch size: 8
Max sequence length: 512
Optimizer: AdamW
Learning rate: 5e-6
Dataset size: ~1.8k curated Python-focused samples
Training hardware: 8GB RAM system (MLX)

Training focused on:

Function completion
Algorithmic correctness
Clean Python structure
Reduced hallucinated commentary

💻 Intended Use

Local coding assistant (with decent performance in other languages too!)
Python function completion
Algorithm practice
Educational use
Lightweight code generation

⚠ Limitations

Primarily optimized for Python (but performs well on other languages too.)
Not benchmarked on multi-language coding
Limited evaluation on mathematical reasoning
Not trained for tool use or multi-step planning

🌍 Philosophy

Powerful coding models do not require massive infrastructure. You don't need a datacenter at home!

Focused training + efficient inference can deliver strong results on modest hardware.

❓ Queries

If you have any questions regarding the model, want to know how it was trained and our pipleine process, how you can make a better version of the model, or you just want to chat about AI, feel free to contact me on Discord at @dqnlabs.

Enjoy this model, for this is the best so far. There's more coming.
