Swift 1.5 Qwen3.8 27b (A must-have for low thinking!)

Just made this post for those who missed it : https://huggingface.co/ukisai/Swift-1.5-Qwen3.8-27b

UkisAI released their updated Qwen 27B (tuned for token efficiency). I grabbed the IQ4\_XS quant to test against Unsloth's Q4\_K\_S:

Low-thinking: UkisAI consistently beat Unsloth in most of my tests.

High-thinking: Unsloth still pulled ahead here.

I was struggling with a custom script in Directory Opus. I gave it to Gemini Flash (medium thinking on Antigravity free tier) it looped for 40 minutes, tried many things, burnt all the weekly limit-tokens, and failed to solve it.

Fed the exact same problem to this 27B model: Fixed it completely in 6 minutes on an old 3090 (67 t/s)

Honestly i was kinda impressed, didn't expect an IQ4\_XS quant of a 27B model in low thinking to beat a major cloud model.
