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: Posted 26th August 2026 at 11:52 pm Recent articles Conceptual integrity and counting lines of code - 19th August 2026 Qwen 3.8 27B is excellent, but it defaults to wildly overthinking things - 16th August 2026 Now we have a timeline of the OpenAI accidental attack against Hugging Face - 7th August 2026 This is a link post by Simon Willison, posted on 26th August 2026. ai 2,205 generative-ai 1,954 llms 1,921 qwen 61 pelican-riding-a-bicycle 136 ai-in-china 107 nvidia-spark 6 Monthly briefing Sponsor me for $10/month and get a curated email digest of the month’s most important LLM developments.
