OpenAI Unveils Critic GPT for Code Review
OpenAI has introduced Critic GPT, an AI model trained on intentional bugs to detect errors in code, achieving an impressive 85% accuracy compared to 25% by human reviewers. Critic GPT's feedback outperformed humans in 63% of cases, using Force Sampling Beam Search to enhance its code reviewing capabilities. Despite its success, the model may struggle with complex outputs and false positives, necessitating human oversight for now. OpenAI plans to integrate Critic GPT into their AI training pipeline for enhanced future models.
Humanoid Robot with Living Skin & Oyster-Inspired Concrete Innovations
Researchers at the University of Tokyo and Harvard have developed a small humanoid robot with lab-grown human skin, enabling lifelike expressions and interactions. The robot utilizes specialized skin cells in a collagen scaffold on a 3D-printed base for flexibility and strength. In sustainable construction, oyster-inspired concrete blends durability and eco-friendliness, with mixes mimicking oyster shells to promote biodiversity and reduce waste. NASA's selection of SpaceX to deorbit the International Space Station by 2030 emphasizes the growing importance of commercial space stations for continued human presence in low-Earth orbit.
In this episode of Discover Daily, we explore OpenAI's CriticGPT, an AI model designed to identify errors in code generated by ChatGPT. CriticGPT catches 85% of errors compared to 25% by humans and its feedback was preferred over human critiques in 63% of cases. OpenAI plans to integrate CriticGPT into their AI training pipeline, potentially leading to more reliable AI models.
Next, we discuss a groundbreaking humanoid robot face created by scientists at the University of Tokyo and Harvard, covered in lab-grown, self-healing human skin cells. The innovative skin consists of human cells in a collagen scaffold on a 3D-printed resin base, enabling the robot to smile and display realistic facial expressions. This technology could revolutionize healthcare and cosmetics testing.
Finally, we explore how oyster-inspired concrete combines the durability of oyster shells with advanced engineering for stronger, eco-friendly building materials. Companies like GROW Oyster Reefs have developed concrete mixes that mimic oyster shells to sustain healthy oyster populations, while Princeton engineers created a cement composite inspired by mother of pearl that's 17 times more crack-resistant and 19 times more stretchable than standard cement. Oyster-inspired concrete promotes biodiversity, reduces erosion, and repurposes waste shells.
