Overview

Qwen3.5 27B is Alibaba's dense mid-size model, available free on ModelScope's inference API. As a dense (non-MoE) architecture at 27B parameters, it avoids the expert-routing trade-offs of MoE models — more consistent performance across diverse prompts. 131K context supports full-document analysis and extended conversations. Uses ModelScope's native API format. Ideal for developers evaluating Qwen's latest dense generation.
