@PerleLabs Middle Tower of Pisa is the AI one! Architectural patterns and the crowd at its base show subtle, "too-perfect" repetitions and blurry textures typical of AI. It lacks the gritty, imperfect details of real stone and the sharp, distinct silhouettes.

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 I pick Left because the lighting transition between the balloon and the sky looks natural. There’s no strange halo effect or overly smooth blending. The smaller balloons in the background also scale realistically and don’t show repeated or distorted patterns.

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! Submissions close Sat, Feb 28 at 11:59pm UTC. Answers revealed Sunday.

@PerleLabs right The left image looks almost too perfect like a stylized promotional render with ultra-clean gradients and controlled blur. The right image has natural noise, contrast variation, and real-world imperfection.

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 The right photo shows highly complex and naturally irregular details such as shapes of the building, realistic lighting, gradients on the mountain and organic crowd on the beach. Also the depth, shadow transitions, and small imperfections which is normal in real photograph.

Perle Human CAPTCHA #5 📸 Let’s keep your captcha streaks alive. One of these vacation photos is real, and one was generated by AI. Which one is real? Reply "left" or "right" and explain why ↓ This week's submissions close Sat, Feb 21th at 11:59pm UTC. Both answers will be revealed on Sunday.

@PerleLabs Right The background has a natural depth of field, with the forest receding realistically into the distance. The textures of the leaves, dirt path, and the tiger's fur are all distinct and detailed.

Perle Human CAPTCHA #4 It's time to put your human judgement to the test again. One of these images of a tiger is a real photograph, one was generated by AI. Which one is real? Reply "left" or "right" and tell us why ↓ This week's submissions close Sat, Feb 14th at 11:59pm UTC. Both answers will be revealed on Sunday 👀

@PerleLabs Right The background elements (potted plants, cutting boards, cloth) are proportionate, and the depth of field is natural, creating a cohesive, lived-in kitchen environment.

Perle Human CAPTCHA #3 📷 One of these images of fruit is a real photograph, one was generated by AI. Which one is real? Reply "left" or "right" and why 👇 You have until Sat, Feb 14th at 11:59pm UTC. This week's answers will be revealed on Sunday.
