Flux image checks
Flux AI Image Detector
Flux images can look like ordinary photos, and they rarely carry signed provenance. Slop or Not reads what metadata there is, then scores the pixels with a classifier trained on millions of human and AI images when no readable provenance or watermark resolves the file. Online checks run on Numen's private Mac server, away from outside AI companies.
A SynthID checker finds stamped images. Slop or Not also checks the ones nobody stamped.
It reads SynthID from Google and OpenAI images, verifies C2PA Content Credentials, reads generator fingerprints, and scans the pixels.
- You can testPhotos, screenshots, product images, receipts, and profile pictures up to 8 MB.
- ResultA probability verdict, AI score, and source details when the file carries them.
- PrivacyChecked on hardware we own and run. We never pass your photo to OpenAI, Google, or any other AI company.
What it checks
Check Flux Images When Provenance Is Missing
Metadata left by the generation or editing app
Photorealistic image artifacts that survive export
Classifier evidence when provenance is absent
Good Uses
- Checking photorealistic portraits from unknown accounts
- Reviewing campaign or ad images before publication
- Testing whether a downloaded Flux image still carries clues
Limits to Know
- Flux images shared through social apps may lose useful metadata
- Small crops can hide enough context to lower confidence
- A probability score should be paired with human review
FAQ
Flux AI Image Detector Questions
Can Slop or Not detect Flux images?
It checks for generation metadata and visual AI signals that can survive export. Confidence depends on image quality, compression, cropping, and what happened to the file after generation.
Is Flux detection different from Stable Diffusion detection?
The workflow is similar, but Flux images have their own visual patterns and source context. Use the Flux detector when that model family is the likely source, and use the broad AI image detector when you are not sure.
Does it need the original file?
Original files usually carry more evidence because metadata and image detail survive. Screenshots and compressed copies can still be checked, but the result may be less certain.
Run the Next Check on Your iPhone or Mac
The Slop or Not app checks images and text on-device, so nothing you check ever leaves your device.
More from Numen
Two more apps that run on your device. Neither needs an account.
Private LLM
A Local AI chatbot for uncensored open-source models that runs offline on iPhone, iPad, and Mac. Private LLM uses OmniQuant and GPTQ quantization tuned per model, so its 3-bit models match the 4-bit models other apps ship.
Clean Links
Most tracking now hides behind link redirects. Clean Links unwraps short links and strips every tracking parameter from a URL before you share it, on iPhone, iPad, Mac, and the web.
