Alright… this is it. Final Human CAPTCHA challenge 👉👉
We saved the best for last. There are 3 images. Only ONE is AI-generated.
Your job is to tell us if it's the one on the Left, Middle, or Right.
Submit your guesses by Sat, Feb 28 at 11:59pm UTC. As usual we'll be revealing the answers on Sunday!
If you got 3+ right, we’ll share how to claim your reward next week.
@PerleLabs Left
The left image’s small balloons have the same shape as the main balloon, with a rounded top and tapered bottom, while the right small balloons have a different shape, with a flat top or a pointed bottom, which is not typical of hot air balloons.
It's the final week of Human CAPTCHA: Round 7
You made it this far… but we’re not going easy on you. One of these is a real photograph of a hot air balloon, the rest is AI-generated. Can you tell which one it is?
Respond with Left, Middle, or Right and tell us why below!

@PerleLabs Right.
The scene has natural imperfections. Slightly uneven road texture, realistic reflections on the car, and building details that match with distance.
Perle Human CAPTCHA #6 🏎️
One of these sports car photos is real. The other was generated by AI.
Comment “left” or “right” with your guess, and tell us why 👀
Submissions close Sat, Feb 21 at 11:59pm UTC. Answers revealed Sunday.
@PerleLabs Right is real
the photo on the right is the real one because the clouds in the sky on the left don't look realistic, and their reflection in the water doesn't match.
With clouds like those, it should be dark there, not that bright.

@PerleLabs AI
AI often creates "hallucinations" in complex textures. If you look closely at the pine trees, the needle patterns are somewhat repetitive and inconsistent, and some branches seem to float or merge into the background in a way that doesn't follow natural growth patterns.
