Outmake picks the UD-IQ2_S size: a 9.3 GB download that uses 10 GB of memory, and writes about 6.1 words (8.1 tokens) a second.
About
Designed to carry complex tasks with many steps through to the end. It reads pictures and video, and it can think before answering when that is switched on.
How it compares
Of the chat models Outmake recommends for a 24 GB Mac that LM Arena rates, its public vote ties it with Gemma 4 26B at the top.
In LM Arena's public vote for reading pictures, it ranks 3rd of the 15 open models rated.
Outmake estimates it is the slowest of the 8 chat models it recommends for a 24 GB Mac. Qwen3.6 35B writes about 5.8 times as fast.
Good to know
It follows the Qwen3.5 and Qwen3.6 series and is built on the design of Qwen3.5.
Sources: Qwen/Qwen3.8-27B model card, Outmake's speed estimates, LM Arena and Hugging Face. Every line comes from one of these.
Ratings
4.4 out of 5, from how people voted on its answers.
LM Arena ratings of October 28, 2026 (CC BY 4.0): people vote between two answers without knowing which model wrote which. The bar ends at 1488, the best any open model has. The Arena tests the full model; a small size on a Mac answers a little worse.

Memory is what llama.cpp's own calculator reported for each size when the catalog was built, with the app's settings. Smaller, Balanced and Best are the three sizes the store names.

The largest size, of those that keep three bits a weight or more, whose memory at an 8K chat is under 92% of the card's; the rest is the desktop's. Estimated from the files, the same way as for a Mac; speed on a PC is not estimated yet. A size that doesn't fit the card still runs, slower, with part of it in ordinary memory.

Badge for the model card
Shows on Qwen3.8 27B's Hugging Face card which Macs run it well, linked to this page. It updates every morning.
Sizes and files are read from unsloth/Qwen3.8-27B-GGUF on Hugging Face and checked every morning. The rating is the model's score on the LM Arena text leaderboard (CC BY 4.0), where people vote between two answers without knowing which model wrote which. Catalog of November 4, 2026.
