# **Qwen3.5-4B-DS-v4-Flash-v1.0-GGUF**

> **Qwen3.5-4B-DS-v4-Flash-v1.0** is a reasoning-capable **4B-parameter** language model built on top of **Qwen/Qwen3.5-4B**. The model was trained using a **single-stage long-context training pipeline** with approximately **4.5K long-context DeepSeek V4 Flash reasoning traces**, along with additional high-quality reasoning traces, to improve long-form reasoning, mathematical problem solving, scientific analysis, coding, and instruction-following capabilities.

> [!NOTE]
> This model is an experimental release and may generate unexpected behaviors or reasoning artifacts in certain scenarios.
