Vibe-coded ComfyUI node unlocks 2MP for Fibo 2.0 Edit, built in 10 minutes with a free LLM

WhiteZero · reddit · 2026-10-22

A Redditor found Fibo 2.0 Edit's default ComfyUI node caps at 1MP, so he pointed OpenCode (with free MiniMax M3.1 Flash) at the Fibo2 Python and node files, described the diffusion model and the goal, and got a working custom node in roughly one shot after 10 minutes.

The open-source node (WhiteZeroX/ComfyUI-Fibo2MP) allows a selectable pixel budget up to 2MP. Above 1MP the model struggles with some details and element transitions, but generally works. It's the author's first published vibe-coded project.
