FLUX-RS

FLUX-RS

FLUX-RS is a remote sensing text-to-image checkpoint obtained by fine-tuning black-forest-labs/FLUX.1-dev on a curated remote sensing corpus. It is designed to improve semantic alignment and visual realism for aerial and satellite scene synthesis, especially in settings that require dense structural details such as buildings, roads, vehicles, farmland parcels, and waterfront layouts.

This model serves as the domain-specialized generative prior used in SHARP: Spectrum-aware Highly-dynamic Adaptation for Resolution Promotion in Remote Sensing Synthesis.

Usage

Diffusers

import torch
from diffusers import FluxPipeline

pipe = FluxPipeline.from_pretrained(
    "BxuanZ/FLUX-RS",
    torch_dtype=torch.bfloat16,
)
pipe.enable_model_cpu_offload()

image = pipe(
    "Satellite imagery showing a modern downtown beside a wide river, several bridges linking both banks, office towers casting long shadows, riverside parks, and dense commercial blocks arranged along the waterfront.",
    height=1024,
    width=1024,
    guidance_scale=4.5,

).images[0]

image.save("flux_rs_sample.png")

With SHARP

For dynamic resolution promotion and the paper-aligned inference pipeline, use the official SHARP codebase:

python run_sharp.py \
  --ckpt_path /path/to/FLUX-RS \
  --prompt "A satellite image of a rural market town with dense shop blocks, a bus station, surrounding crop fields, narrow feeder roads, and mixed residential and commercial parcels." \
  --width 1024 \
  --height 1024
