Qwen 发布开源多模态 MoE 模型 Qwen3.8-Flash-Next，作为 Qwen4 架构的早期预览。模型总参数 125B，仅激活 6B 参数，带来显著性能提升。作者已在 DGX Spark 上通过 Unsloth 量化版本试用，包括 72.5GB 的 UD-IQ1_S 和 78.9GB 的 UD-Q2_K_XL 版本。

Another open weights model from Qwen. This one is "a multimodal MoE model that also serves as an early preview of the architecture used in Qwen4".

It's pretty big: 125B tokens, but only 6B active which means it gets a significant performance boost.

I've been trying it out on a DGX Spark using these Unsloth quantized models. I'm still exploring the model - so far I've tried the 72.5GB UD-IQ1_S one (producing these pelicans) and the 78.9GB UD-Q2_K_XL (producing these).

My favorite so far was this xhigh reasoning effort one from UD-Q2_K_XL:
