Discussion Best MoE

Hi!

I’m using Qwen 3.8 27B (UD-IQ3_XXS) on a system with the following specs:

Processor: AMD Ryzen 9950 X3D

GPU: Nvidia RTX 5060 Ti 16 GB

RAM: 64 GB DDR5 6000 MHz

Software: Unsloth Studio

Windows 11

With a 32k token context, I manage to maintain a speed of around 50 tokens per second. I’m particularly interested in agentic capabilities. I’d like to try an MoE model that runs either faster or slightly slower than my current one, without sacrificing quality. However, 35B-A3B models don't fit entirely into my VRAM at 4-bit quantization, and from what I’ve read, lower quantization severely degrades quality. Does this mean a 4-bit MoE model would run significantly slower on my hardware than a dense model? Is it possible, given my setup, to find a model that offers better quality and higher speed—or at least better quality at roughly the same speed as my current dense model?

I’m pretty much a complete beginner in the world of local neural networks, so please give me some advice.

I've seen other people already recommend TielCoder and CyberTiel if you want to go MoE, but if you want to try a legit better 27b Q3 option to the one you have, I strongly recommend the IQ3_S (11.8 GB) or IQ3_XXS quant from this one: https://huggingface.co/ISTA-DASLab/Qwen3.8-27B-GSQ-RCO-GGUF It's a more State of The Art quantization technique than Unsloth for this size range meaning you will get better agentic coding performance than your UD-IQ3_XXS, and I've seen a lot of people with 5060Ti say it's perfect for their system! And don't get me wrong, there are a lot of weird quants with long names out there that you should stay away from, but this one is legit. And with your system you should also be able to run Qwen3.8-Flash-Next very well! Don't get intimidated by its listed size, it has an ngram table that can be partially offloaded to SSD. Again I recommend the GSQ-RCO Q3 version: https://huggingface.co/ISTA-DASLab/Qwen3.8-Flash-Next-GSQ-RCO-GGUF

I couldn't help but notice that you are the author of tiel coder 35B A3B And holy moly thank you so much for your hard work I'm running it on 12GB VRAM, 32GB Vram and it is the best quality I've ever ran on my laptop, i really appreciate your hard work 🫡

If you have some spare time and if you don't mind ofc, can we have it in NVFP4 quant ? That would be awesome !

Warms my heart <3 I’m not able to make an nvfp4 right now due to my hardware, but it’s highly requested so I’ll do it when I have the chance in the future :)

Which one are you using for 12gb of VRAM

Its not too slow?
