**[Qwen3.8-Flash-Next](https://qwen.ai/blog?id=qwen3.8-flash-next)**

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](https://huggingface.co/unsloth/Qwen3.8-Flash-Next-GGUF). I'm still exploring the model - so far I've tried the 72.5GB UD-IQ1\_S one (producing [these pelicans](https://tools.simonwillison.net/markdown-svg-renderer#url=https%3A%2F%2Fgist.github.com%2Fsimonw%2Ff9c69ebdab90d8a45b8de4742cc7b840)) and the 78.9GB UD-Q2\_K\_XL (producing [these](https://tools.simonwillison.net/markdown-svg-renderer#url=https%3A%2F%2Fgist.github.com%2Fsimonw%2F6ba7cbfc1a9336986703b41f7fccd73a)).

My favorite so far was this xhigh reasoning effort one from UD-Q2\_K\_XL:
