# Fibo 2.0

Repackaged model files for ComfyUI.

Original model repository:

- https://huggingface.co/briaai/Fibo-2.0-dev
- https://huggingface.co/briaai/Fibo-2.0-edit-turbo

Place the files in the following folders:

## Changes from the original

- `bf16`: the diffusers transformer shards merged into one file, with keys renamed to ComfyUI's layout. Attention `to_q`/`to_k`/`to_v` weights are concatenated into `qkv`, and the cross-attention and Perceiver `to_k`/`to_v` into `to_kv`. Weight values are unchanged (bf16).
- `int8_convrot.safetensors`: the same weights quantized to int8 (Hadamard rotation, per-channel scales), with the adaLN modulation layers kept in bf16. Outputs differ slightly from the original.
- `w1/w3 fused into w13 and the FFN hidden width zero-padded to 9728`
