A Brazilian fitness influencer has earned the stamp of approval for “perfection” from artificial intelligence.

Crowned as having “the perfect body” by AI, 25-year-old Karol Rosalin has set a new standard in the fitness world.

Her recognition came after the AI model reportedly analyzed her well-being, health, and strength in addition to symmetry, proportion, and aesthetic harmony.

The São Paulo resident’s rise to the title was spotlighted in a recent announcement by Playboy Australia, which described her physique as the “ideal in the fitness world.”

“According to artificial intelligence, fitness influencer @karolrosalin has the perfect body in terms of definition and is ideal in this fitness world,” they declared in an Instagram post.

Karol isn’t just a fitness influencer; she is also an adult content creator with more than 876,000 followers on Instagram.

The fitness enthusiast credits her success to a strict workout regimen and a carefully curated diet. However, Karol’s journey wasn’t always as calculated and seamless as it appears today.

“Seeing the results in the mirror is already a victory,” she told the magazine, as quoted by the Daily Mail.

“Being recognized as the ‘Perfect Fitness Woman’ is incredible!” she added.

Reflecting on her early days, she admitted she didn’t know what she was doing in the beginning but eventually found the right “balance” for her body.

“In the beginning, I didn’t know how to train properly. I went through periods when I was thinner or more muscular,” she said.

“But today I found the balance for my body,” she added.

Her current regimen involves five days of weight training each week, coupled with daily aerobic exercises.

As for her diet, it’s a wholesome mix of fruits, vegetables, oats, and chicken.

“I don’t do anything crazy, everything I eat is part of a plan to keep my health up to date,” she said.

For breakfast, she mostly whips up some scrambled eggs, cassava, papaya, pineapple, and oats with cinnamon, with some coffee to wash it all down.

Baked sweet potato chips and vegetable frittatas are also often made in her kitchen.

Rosalin’s AI-approved body also reflects shifting preferences in the fitness world. According to Playboy Australia, she embodies a growing trend toward less muscular, more balanced physiques.

A recent survey by the magazine found that 80% of men favored women with a more attainable and natural-looking build over muscular body types.

Karol’s recognition as having the “perfect female body” offers a glimpse into how artificial intelligence evaluates physical attributes, but it also opens the door to a larger conversation about AI’s influence on societal standards.

A 2023 study—titled Human Beauty according to Artificial Intelligence—investigated how AI perceives humans and highlighted a troubling trend.

Many AI models learn about humanity through the internet, which often provides distorted and unfiltered representations.

The study found that AI-generated images of women often featured exaggerated, sexualized features—such as oversized breasts—reflecting the biases and stereotypes prevalent online.

As AI continues to evolve, its role in shaping content for entertainment, education, and beyond will expand. Hence, there is an urgent need for a balanced and socially conscious approach to how AI is trained to “see” and represent humanity.

While AI holds transformative potential, experts say that its impact is only as good as the data it is trained on.

“As anticipated in our article ‘Human Beauty According to AI,’ artificial intelligence is beginning to play a significant role as a content creator on social media,” Dr. Nitzan Kenig, co-author of the study, told Bored Panda via email.

“AI is undoubtedly a transformative technology with the potential to profoundly impact humankind. However, its effectiveness is inherently tied to the quality of the data on which it is trained,” said the Mallorca-based plastic surgeon and AI researcher.

To harness AI’s potential responsibly, it’s essential to prioritize diverse, balanced, and inclusive data during its development.

“AI models rely on datasets for learning. If these datasets contain societal biases or promote unrealistic standards, the AI may inadvertently perpetuate those views, making it difficult to guide future generations toward a balanced and healthy perspective on body image and beauty,” said the Chief Medical Officer at Instituto Rubi. “This is why it is critical to use AI responsibly and wisely when creating content.”

As we stand at the crossroads of technological progress, Dr. Nitzan emphasized that AI’s power should be guided by human values, promoting healthy beauty standards rather than reinforcing harmful biases.

“We are currently at a pivotal point: if harnessed thoughtfully, AI can be an extraordinary tool for good. However, we must remain vigilant to ensure it aligns with and upholds our human values,” he concluded.

“Perfection is an individual analysis,” one social media user said following the news
