A research team from the United States and the United Kingdom has recently succeeded in reviving a chatbot code known as ELIZA, which is considered the first electronic chatbot in history. According to their paper published on the arXiv preprint server, this code was originally written by the late MIT professor Joseph Weizenbaum in the 1960s. In 2021, an MIT archivist named Miles Crowley discovered printed copies of this code in a box containing Weizenbaum's personal belongings. The revival of this code marks an important milestone in the history of artificial intelligence.

AI drug development company Genesis Therapeutics recently announced that it has secured additional investment from Nvidia's venture capital arm, NVentures, though the specific amount remains undisclosed. This move marks a further deepening of the collaboration between the two parties, aimed at accelerating the development of Genesis's AI platform GEMS (Genesis Exploration of Molecular Space), which focuses on utilizing physics-based AI for structure-driven drug design.

GPT-4, OpenAI's language model, passed the Japanese National Physical Therapist Exam without additional training, achieving an accuracy rate of 73.4%. It excelled in handling pure text questions with an accuracy of 80.5%, but performed poorly in solving practical problems and dealing with questions containing images and tables, with accuracy rates of 46.6% and 35.4%, respectively. The research reveals the limitations of AI in certain areas, particularly in understanding complex contexts and visual information. Despite being trained on English data, GPT-4 still performed effectively when processing Japanese input.

The Transformer architecture, a star in the field of artificial intelligence, has led a revolution in natural language processing with its self-attention mechanism at its core. However, when handling long contexts, the resource consumption of self-attention calculations becomes a bottleneck. To address this issue, researchers have proposed the Tree Attention method, which decomposes the calculation tasks through tree reduction to improve efficiency. This method not only reduces communication overhead and memory usage but is also 8 times faster than existing methods in a multi-GPU environment. The introduction of Tree Attention not only enhances performance.
