ALT What if artificial intelligence could run on light instead of electricity? Scientists at Tsinghua University in China have developed a brain-inspired chip called **Taichi** that uses light to perform AI calculations. Instead of relying on traditional electronic circuits, it uses beams of light to process information. But here is the surprising part: the researchers reported an energy efficiency of up to **160 trillion operations per watt** in their tests. This could point toward a future where AI systems perform complex tasks while using far less energy. Why does this matter? Today's AI systems need enormous computing power, which can require large amounts of electricity and generate significant heat. Photonic chips like Taichi could offer a new way to tackle this challenge.
