At the grand opening of the 2024 Zhongguancun Forum Annual Conference, the AI "little girl" named "Tongtong" made a captivating debut as one of the ten pivotal scientific and technological breakthroughs. Adorned with a charming hairband and attired in playful pink shorts, this AI, originally designed with the cognitive capabilities of a 3-year-old, was crafted by the esteemed Beijing Institute of General Artificial Intelligence. Remarkably, within just a year, "Tongtong" has not only undergone a significant transformation in appearance but has also witnessed substantial enhancements in her cognitive, emotional, and autonomous decision-making skills. Now, she is proficient in completing cognitive assessments on par with those administered to 5-6 year old children. Leveraging an innovative cognitive architecture and a proprietary learning and reasoning framework, "Tongtong" showcases an adaptability that surpasses that of her human counterparts of the same age.
