Qwen3-1.7B Chat

Qwen3-1.7B Chat is a preference-aligned conversational language model built by fine-tuning Qwen3-1.7B-Base through a two-stage post-training pipeline:

Supervised Fine-Tuning (SFT) on UltraChat
Direct Preference Optimization (DPO) using UltraFeedback, Intel Orca and Capybara

The model is designed to provide more natural, helpful and conversational responses while preserving the strong capabilities of the base model.

Full model, documentation, benchmarks and training details are available on Hugging Face:

Merged Model: https://huggingface.co/ayushshah/Qwen3-1.7B-Chat
LoRA Adapter: https://huggingface.co/ayushshah/Qwen3-1.7B-Chat-LoRA
SFT Model: https://huggingface.co/ayushshah/Qwen3-1.7B-UltraChat-SFT

Notes

This model is intended for research and general conversational AI use. As a 1.7B parameter model, it may still struggle with complex reasoning, factual accuracy and highly specialized domains compared to much larger language models.
