Open-source .char format brings one-file consistent characters to both Flux 2 and Krea 2

ashishsanu · reddit · 2026-08-21

A developer released the open-source .char unified character format (part of Inline Studio, GPL3): one character file works across multiple image models — currently Flux 2 (Klein 4B/8B/dev) and Krea 2, with Minimax H3 in progress.

How it works

File structure: a manifest, 5 reference images, YuNet 512px face crops, a locked description, SFace 128-d + DINOv2 768-d identity centroids for scoring, and per-model payloads (Flux refs / a 183MB Krea LoRA).

Training and generation workflows are downloadable; sample models with full training params are on HuggingFace.
