# SmilyAI Labs T1-Mini-Preview

**T1-Mini-Preview** is an early preview of the upcoming **T1-Mini** model from **SmilyAI Labs**.

T1-Mini-Preview is based on **Qwen/Qwen3.5-4B** and was fully fine-tuned on **Bc-AI/SFT-Ultra**, a curated instruction-tuning dataset prepared for SmilyAI's small-model research.

## Training

The model was trained in two main stages:

1. **Supervised Fine-Tuning (SFT)** — trained the base model on our curated instruction and reasoning data.
2. **Direct Preference Optimization (DPO)** — further refined the model's responses using preference-based training.

This two-stage pipeline was designed to improve instruction following, response quality, and overall conversational behavior while keeping the model relatively small and efficient.

## Model Status

**T1-Mini-Preview is a preview release**, not the final T1-Mini model. Training, evaluation, and further refinement are still ongoing.

We are releasing this version so the community can experiment with it and provide feedback while development continues.

## Base Model

- **Base:** Qwen/Qwen3.5-4B
- **Training:** Full fine-tuning
- **Primary language:** English
- **Fine-tuning dataset:** Bc-AI/SFT-Ultra
- **Training stages:** SFT → DPO
- **License:** Apache 2.0

## About SmilyAI Labs

**SmilyAI Labs** is a small open-source AI project focused on building capable, efficient, and accessible AI models.

We're experimenting with smaller models that can deliver strong performance without requiring enormous amounts of compute.

🚀 **T1-Mini-Preview is one step toward that goal.**

## Disclaimer

This is an experimental preview model. Its behavior and capabilities may differ from the final T1-Mini release, and it may occasionally produce incorrect, inconsistent, or undesirable outputs.
