Qwen3.8 Flash

by Alibaba

Qwen3.8-Flash is the Qwen team's production model based on the open-weight Qwen3.8-Flash-Next, which Alibaba released in August 2026 as an experimental preview of the architecture that will underpin Qwen4. Qwen describes it as the latest multimodal model in the family, combining strong reasoning and generation with speed. It accepts text, images and video, outputs text, and supports a context window of roughly 1 million tokens with up to 131,072 output tokens. The underlying Flash-Next design is a Mixture-of-Experts model with 125B total and 6B activated parameters, plus a 51B n-gram embedding. It combines hybrid attention (Gated DeltaNet with Qwen Sparse Attention), gated residuals and 512 experts across 48 layers. The model thinks by default, with thinking switchable and adjustable through reasoning effort, and supports function calling and structured outputs. On Qwen's numbers, Flash-Next scores 91.7 on GPQA Diamond, 62.5 on SWE-bench Pro, 73.9 on CoWorkBench and 84.5 on AndroidWorld. Alibaba highlights coding assistance, agentic workflows and visual understanding, such as fixing code autonomously, operating desktop applications and analyzing charts and long videos. It fits long-document and codebase work where a large context and low active-parameter count matter.
