Dual 4090 local computer use setup: Qwen for reasoning, GUI-Owl for action
doodlestein · x · 2026-08-19
A user proposed a local AI agent deployment setup utilizing dual RTX 4090s on a Linux machine. The concept involves dedicating one GPU to the Qwen3.8-27B model for core reasoning and the other to a computer control model like GUI-Owl-1.5, with plans to also run Simular on a Mac Mini.
- Architecture: Separating reasoning and execution to optimize resource usage by deploying the LLM and GUI interaction model on different GPUs.
- Models: Qwen3.8-27B (Uncensored) offers multiple quantization formats (FP8/GGUF/MLX/BF16); GUI-Owl-1.5 focuses on computer interface manipulation.
