Qwen3.8-Flash-Next ( via ) 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:
