OpenAI releases upgraded ChatGPT
The company says ChatGPT-5, unveiled on Thursday, can answer users' questions more quickly and is "less prone to hallucinations and pretending to know things."
Open AI also says the model is "a unified system that knows when to respond quickly and when to think longer to provide expert-level responses."
Chief Executive Officer Sam Altman says, "You get access to an entire team of PhD-level experts in your pocket, helping you with whatever you want to do."
ChatGPT is estimated to have around 700 million active weekly users.
US tech giant Google and Chinese startup DeepSeek are also investing more in improving the performance of their generative AI models, as use of the technology rapidly expands around the world.

Close aides to North Korean leader Kim recently visited China: sources
BEIJING - Two aides to North Korean leader Kim Jong Un visited Beijing after mid-July in trips believed to be linked to construction projects, sources familiar with China-North Korea relations said Sunday. Their China visits were not covered by North Korea's state-run media, making it rare for the movements of Kim's aides to become known outside official reports. The two often accompany the leader during his inspections of construction projects in North Korea. The visits suggest economic exchanges between Beijing and Pyongyang are normalizing, despite speculation that bilateral relations may have recently become strained as North Korea deepens its military ties with Russia. China is North Korea's closest and most influential ally in economic terms, but mutual visits of senior officials have been relatively rare in recent times, even since the lifting of strict travel restrictions imposed during the COVID-19 pandemic. The two aides are Kim Bok Nam, a senior military officer and brigade commander, and an unnamed senior official of the ruling Workers' Party of Korea, according to the sources. They visited the Chinese capital for four days from July 12. The senior party official then traveled to Beijing alone on Aug. 2 and returned to Pyongyang three days later. Their detailed itinerary in China remains unknown. In June, the two accompanied Kim Jong Un when the leader inspected hospitals and a leisure complex under construction in Pyongyang. Since December last year, Kim Bok Nam has frequently traveled with Kim Jong Un to the sites of major construction projects, including the Wonsan Kalma tourist area on the east coast, which opened in July, media reports showed. The unnamed senior party official was first covered by official media in June this year. On Aug. 1, he accompanied Kim Jong Un to a large-scale greenhouse farm near Sinuiju in the northwestern part of the country.

Yomiuri Sues U.S. AI Startup over Use of Articles; Perplexity Allegedly Used Over 100,000 News Stories
Three Yomiuri Shimbun newspaper companies have filed a lawsuit against a U.S. startup company that allegedly used a large number of Yomiuri Shimbun articles and images for a generative AI-powered search engine without permission. The Yomiuri Shimbun; The Yomiuri Shimbun, Osaka; and The Yomiuri Shimbun, Seibu filed the lawsuit demanding that Perplexity AI, Inc. stop using the newspaper's articles and seeking damages of about ¥2.17 billion in the Tokyo District Court on Thursday. The three companies are under The Yomiuri Shimbun Holdings. This is the first time a major Japanese media company has filed such a lawsuit, although several AI-related businesses in Europe and the United States have been taken to court for the unauthorized use of copyrighted material by generative AI. Established in 2022, Perplexity provides a search service that parses the latest online information to compile answers to questions typed in by users. A conventional search engine will display a list of websites related to the search terms entered by a user, but Perplexity pitches its service as an 'answer engine' that summarizes information gleaned online. This enables users to acquire information they want without looking through individual websites. In its lawsuit, The Yomiuri Shimbun claims that Perplexity copied articles from the Yomiuri Shimbun Online (YOL) digital service and sent answers with content similar to these articles to its users. The Yomiuri Shimbun claims this violated the right of reproduction and the right to public transmission under the Copyright Law. Perplexity allegedly acquired 119,467 Yomiuri articles without permission between February and June this year for the purpose of generating answers for its users. The Yomiuri Shimbun decided to seek damages of ¥16,500 per article, calculated based on a regular licensing fee. The amount of compensation being sought could increase depending on the findings of a further investigation. In addition, conventional search engines encourage users to visit the YOL service, which generates advertising revenue for The Yomiuri Shimbun. However, Perplexity's service results in fewer online visits to the YOL. The Yomiuri Shimbun claims that this is causing a drop in advertising revenue, which also constitutes an infringement of its business interests. About 2,500 reporters are involved in news coverage for The Yomiuri Shimbun. Consequently, the newspaper believes Perplexity has been getting a 'free ride' on the activities of a media organization that devotes 'great effort and expense' to creating news articles. The Yomiuri Shimbun also is seeking compensation for lost advertising income. In response to The Yomiuri Shimbun's emailed request for comment, Perplexity sent a message that said: 'We are deeply sorry for the misunderstanding this has caused in Japan. We are currently working hard to understand the nature of the claims. We take this very seriously, because Perplexity is committed to ensuring that publishers and journalists benefit from the new business models that will arise in the AI age.' In October 2024, Dow Jones, a division of News Corp., filed a lawsuit together with another company alleging copyright infringement by Perplexity. That case is pending in federal district court in New York. Perplexity has rejected the claims in that case and insists that its search function is based on publicly available facts that are not protected by copyright laws. Yomiuri warns of negative impact The Yomiuri Shimbun Holdings' Corporate Communications Department issued a statement that said: 'Allowing a company to free ride on the results of our reporting would negatively affect our accurate news coverage backed by our research, and could undermine the foundations of democracy. We hope this lawsuit will raise questions about rules on the rapidly spreading use of generative AI and how it should be used and applied.'

Media Organizations in West Sue Generative AI Firms Over Copyright Infringement; Organizations in Japan Likely to Follow Suit
There have been a series of cases in which media organizations in the West have sued generative artificial intelligence companies for copyright infringement over using their articles without permission. There are already more than 30 such news organizations, and many of them are located in the United States. In Japan, it has been pointed out that there are issues with the Copyright Law, as it fails to prevent generative AI companies from using news articles for free to train their AI systems. It is likely that more media organizations in Japan will take their cases to court. Generative AI services, such as OpenAI's ChatGPT, can be trained, as well as gather information from various online sources, allowing it to answer users' questions. Therefore, stories written by media organizations are vital for generative AI firms to improve the accuracy of their products, as the articles are thoroughly fact checked. If AI companies obtain permission from the media organizations to use the stories as a study tool or reference, it would not be an issue. However, many are concerned that the stories have been used without consent. According to British media industry journal Press Gazette, there were at least eight cases as of July in which AI development companies were sued for using stories without permission. The defendants include OpenAI, Microsoft Corp. and Perplexity, all U.S. companies. In one of the cases, The New York Times filed a lawsuit against OpenAI and Microsoft, which are affiliated with each other, in December 2023. The lawsuit claimed that several millions of articles had been used for AI training and other purposes without permission, resulting in several billions of dollars in damages. Specifically, the newspaper claimed that when ChatGPT was asked to provide what was written in a New York Times article, which was not available for free, about an avalanche in the state of Washington in 2012, the generative AI included parts from that very article almost word for word. There are also cases in which generative AI companies become affiliated with media organizations and make payments to them. It has been reported that Inc. will pay up to $2.5 million (about ¥3.7 billion) annually to The New York Times to use their articles for generative AI services. However, Press Gazette reports that there have been only 30 or so such cases.
