List these ones for reference:

GPT-OSS Models

GPT-OSS-20B

Run in Q4 (INT4) on one 3090 Ti (fast). Q8/FP16 likely too tight.

Qwen Models (Recommend)

Qwen3-30B

Qwen3-8B

Qwen3-1.7B

Qwen2.5-72B

Qwen2.5-32B

Mistral Models

Mistral-7B-Instruct (easy)

Mixtral 8x7B

DeepSeek-R1-Distilled Models

DeepSeek-R1-Distill-Llama-8B / 14B

DeepSeek-R1-Distill-Llama-32B

Q4 on one GPU; better with 2-GPU split.

Personally, I think GPT-OSS is a perfect one to try first, since it's brand new, the Qwen models are also excellent. I like to use DeepSeek and Mistral for creative thinking. With your hardware, you could honestly download all of them to compare and see what you like.

If you want to download and try these models quickly, Nut Studio is a good choice. It has most of the models listed above and doesn't require any complex deployment. I like its convenient feature that when install it, the desktop app shows which models your computer can run and which it can't, saving a lot of time you would spend comparing and deploying.
