📖 Overview

Motivation: Scene text editing is a challenging task that aims to modify or add text in images while maintaining the fidelity of newly generated text and visual coherence with the background. The main challenge of this task is that we need to edit multiple line texts with diverse language attributes (e.g., fonts, sizes, and styles), language types (e.g., English, Chinese), and visual scenarios (e.g., poster, advertising, gaming).
Contribution: We propose FLUX-Text, a novel text editing framework for editing multi-line texts in complex visual scenes. By incorporating a lightweight Condition Injection LoRA module, Regional text perceptual loss, and two-stage training strategy, we significantly significant improvements on both Chinese and English benchmarks.

News

2025-07-16: 🔥 Update comfyui node. We have decoupled the FLUX-Text node to support the use of more basic nodes. Due to differences in node computation in ComfyUI, if you need more consistent results, you should set min_length to 512 in the code.

2025-07-13: 🔥 The training code has been updated. The code now supports multi-scale training.
2025-07-13: 🔥 Update the low-VRAM version of the Gradio demo, which It currently requires 25GB of VRAM to run. Looking forward to more efficient, lower-memory solutions from the community.
2025-07-08: 🔥 ComfyUI Node is supported! You can now build an workflow based on FLUX-Text for editing posters. It is definitely worth trying to set up a workflow to automatically enhance product image service information and service scope. Meanwhile, utilizing the first and last frames enables the creation of video data with text effects. Thanks to the community work, FLUX-Text was run on 8GB VRAM.

🔥 Quick Start

Here's a basic example of using FLUX-Text:

python

import numpy as np
from PIL import Image
import torch
import yaml

from src.flux.condition import Condition
from src.flux.generate_fill import generate_fill
from src.train.model import OminiModelFIll
from safetensors.torch import load_file

config_path = ""
lora_path = ""
with open(config_path, "r") as f:
    config = yaml.safe_load(f)
model = OminiModelFIll(
        flux_pipe_id=config["flux_path"],
        lora_config=config["train"]["lora_config"],
        device=f"cuda",
        dtype=getattr(torch, config["dtype"]),
        optimizer_config=config["train"]["optimizer"],
        model_config=config.get("model", {}),
        gradient_checkpointing=True,
        byt5_encoder_config=None,
    )

state_dict = load_file(lora_path)
state_dict_new = {x.replace('lora_A', 'lora_A.default').replace('lora_B', 'lora_B.default').replace('transformer.', ''): v for x, v in state_dict.items()}
model.transformer.load_state_dict(state_dict_new, strict=False)
pipe = model.flux_pipe

prompt = "lepto college of education, the written materials on the picture: LESOTHO , COLLEGE OF , RE BONA LESELI LESEL , EDUCATION ."
hint = Image.open("assets/hint.png").resize((512, 512)).convert('RGB')
img = Image.open("assets/hint_imgs.jpg").resize((512, 512))
condition_img = Image.open("assets/hint_imgs_word.png").resize((512, 512)).convert('RGB')
hint = np.array(hint) / 255
condition_img = np.array(condition_img)
condition_img = (255 - condition_img) / 255
condition_img = [condition_img, hint, img]
position_delta = [0, 0]
condition = Condition(
                condition_type='word_fill',
                condition=condition_img,
                position_delta=position_delta,
            )
generator = torch.Generator(device="cuda")
res = generate_fill(
    pipe,
    prompt=prompt,
    conditions=[condition],
    height=512,
    width=512,
    generator=generator,
    model_config=config.get("model", {}),
    default_lora=True,
)
res.images[0].save('flux_fill.png')

🤗 gradio

You can upload the glyph image and mask image to edit text region. Or you can use manual edit to obtain glyph image and mask image.

first, download the model weight and config in HuggingFace

python app.py --model_path xx.safetensors --config_path config.yaml

💪🏻 Training

Download training dataset AnyWord-3M from ModelScope, unzip all *.zip files in each subfolder, then open *.json and modify the data_root with your own path of imgs folder for each sub dataset.
Replace the old annotations in AnyWord with the new annotations. Change the dataset annotations path and image_root in src/train/data_word.py.

python

json_paths = [
        ['dataset/Anyword/data_text_recog_glyph/Art/data-info.json', 'AnyWord-3M/ocr_data/Art/imgs/'],
        ['dataset/Anyword/data_text_recog_glyph/COCO_Text/data-info.json', 'AnyWord-3M/ocr_data/COCO_Text/imgs/'],
        ['dataset/Anyword/data_text_recog_glyph/icdar2017rctw/data-info.json', 'AnyWord-3M/ocr_data/icdar2017rctw/imgs'],
        ['dataset/Anyword/data_text_recog_glyph/LSVT/data-info.json', 'AnyWord-3M/ocr_data/LSVT/imgs'],

Download the ODM weights in HuggingFace and change odm_loss/modelpath in the config file.
(Optional) Download the pretrained weight in HuggingFace and change reuse_lora_path in the config file.
Run the training scripts. With 48GB of VRAM, you can train at 512×512 resolution with a batch size of 2 in LoRA rank 8.

bash train/script/train_word.sh

📊 Evaluation

For Anytext-benchmark, please set the config_path, model_path, json_path, output_dir in the eval/gen_imgs_anytext.sh and generate the text editing results.
