Introduction of Qwen3.5-4B-Instruct-SingleTurn

Model Details of Qwen3.5-4B-Instruct-SingleTurn

Qwen3.5-4B-Instruct-SingleTurn

This repository contains a fine-tuned version of Qwen/Qwen3.5-4B optimized specifically for single-turn English tasks .

🎯 Model Overview
  • Base Model: Qwen/Qwen3.5-4B
  • Language: English (primary)
  • Intended Use: Single-turn instruction-following, downstream fine-tuning, and lightweight deployment.
  • Key Improvements: Suppresses the base model's tendency for prolonged Chain-of-Thought (CoT) reasoning and reduces unwanted generation of Chinese text.
🛠️ Training Details

The model was fine-tuned using the following configuration and hyper-parameters:

  • Dataset: agentlans/sft-data sample_k50000
  • Sequence Handling: Packed sequences with a 1024 token cutoff length
  • Attention: FlashAttention-2 ( flash_attn )
  • Learning Rate: 2e-5 (1.0 epoch)
  • Regularization: NEFTune (alpha = 5)
  • PEFT Method: LoRA via rsLoRA
    • Rank: 16
    • Alpha: 32
    • Dropout: 0.05
⚠️ Limitations & Biases
  • Scale Constraints: As a compact 4B parameter model, expect occasional factual inaccuracies and basic reasoning errors.
  • Repetition: Extended responses may occasionally become repetitive.
  • Domain Focus: Strictly optimized for English instruction, programming, and mathematics.
  • Interaction Style: Not designed for multi-turn conversational chatbots, roleplay, or creative writing tasks.
