Fibo 2.0 GGUF

This repository contains GGUF quantizations of Fibo 2.0 Dev and Fibo 2.0 Edit Turbo. The Dev variant supports text-to-image and image editing. Edit Turbo is distilled for four-step image editing and is not intended for text-to-image.

Both variants use the Fibo 2.0 architecture. Dev uses 50 steps and CFG 5 for text-to-image. Edit Turbo uses 4 steps and CFG 1 for image editing.

Example outputs

Fibo 2.0 Dev

Fibo 2.0 Edit Turbo

The edit workflow uses the included fibo2-test-input.png. Copy it to ComfyUI/input/, or replace it with your own image in the workflow's Load Image node.

Quantizations

File sizes are shown in GiB. Standard GGUF files use common GGML formats. Q8_CR uses the custom ConvRot layout and requires comfyui-gguf-reboot.

Variant	Quant	Format	Size	File
Dev	Q8_0	Standard GGUF	8.29 GiB	fibo2-dev-Q8_0.gguf
Dev	Q6_K	Standard GGUF	6.48 GiB	fibo2-dev-Q6_K.gguf
Dev	Q4_K_M	Standard GGUF	5.16 GiB	fibo2-dev-Q4_K_M.gguf
Dev	Q8_CR	Proprietary, comfyui-gguf-reboot	7.83 GiB	fibo2-dev_Q8_CR.gguf
Edit Turbo	Q8_0	Standard GGUF	8.29 GiB	fibo2-edit-turbo-Q8_0.gguf
Edit Turbo	Q6_K	Standard GGUF	6.48 GiB	fibo2-edit-turbo-Q6_K.gguf
Edit Turbo	Q4_K_M	Standard GGUF	5.16 GiB	fibo2-edit-turbo-Q4_K_M.gguf
Edit Turbo	Q8_CR	Proprietary, comfyui-gguf-reboot	7.83 GiB	fibo2-edit-turbo_Q8_CR.gguf

ComfyUI setup

Fibo2 requires ComfyUI core commit 87ed5a066d9c4660ef42100fd01a888da6994856 or newer, plus comfyui-gguf-reboot. Load the GGUF with UnetLoaderGGUFDynamicVRAM from models/diffusion_models/.

Download the Qwen3-VL 4B Int8 ConvRot text encoder and place it at ComfyUI/models/text_encoders/qwen3vl_4b_int8_convrot.safetensors.

Download the FLUX.2 VAE and save it as ComfyUI/models/vae/fibo2-flux2-vae.safetensors so it does not replace another FLUX.2 VAE.
