OpenAI has confirmed that a distributed denial-of-service (DDoS) attack is behind “periodic outages” affecting ChatGPT and its developer tools.

ChatGPT, OpenAI’s AI-powered chatbot, has been experiencing sporadic outages for the past 24 hours. Users who attempted to access the service have been greeted with a message stating that “ChatGPT is at capacity right now,” and others, including TechCrunch, have been unable to log into the service.

OpenAI CEO Sam Altman initially blamed the issue on interest in the platform’s new features, unveiled at the company’s first developer conference on Monday, “far outpacing our expectations.” OpenAI said the issue was fixed at approximately 1 p.m. PST on November 8.

Chptr, an app for sharing and holding onto memories of lost loved ones, has raised $1.5 million in seed funding. The app is designed to give people a way to encapsulate the life of their loved ones by inviting others to share and store stories, images, audio messages, videos and more all in one place.

The startup was founded in 2020 by Rehan Choudhry, who came up with the idea for the app when he was helping his wife, a news anchor at CBS New York, put together video tributes for the first victims of COVID-19 in New York City. Choudhry told TechCrunch in an interview that the pair was reaching out to the families, friends, neighbors and colleagues of the victims to paint a picture of what their life was like.

“The thing I realized after talking to a lot of families was that these videos served as almost a reunion point for people that they will continue to grieve around,” Choudhry said. “We noticed that the grieving process that would normally take 90 days was extended to months because they had something to rally around. So then the question for me was why doesn’t everyone on the planet have access to this because we all have smartphones and social media. So I went down the rabbit hole of discovery and it brought me to Chptr.”

The technology that makes it possible, called semantic hearing, could pave the way for smarter hearing aids and earphones, allowing the wearer to filter out some sounds while boosting others.

The system, which is still in prototype, works by connecting off-the-shelf noise-canceling headphones to a smartphone app. The microphones embedded in these headphones, which are used to cancel out noise, are repurposed to also detect the sounds in the world around the wearer. These sounds are then played back to a neural network, which is running on the smartphone; then certain sounds are boosted or suppressed in real time, depending on the user’s preferences. It was developed by researchers from the University of Washington, who presented the research at the ACM Symposium on User Interface Software and Technology (UIST) last week.

The team trained the network on thousands of audio samples from online data sets and sounds collected from various noisy environments. Then they taught it to recognize 20 everyday sounds, such as a thunderstorm, a toilet flushing, or glass breaking.

Scientists have long been trying to successfully switch from lithium-ion to lithium-metal batteries. However, there is one issue that has been causing a delay in this transition: traditional electrolytes do not perform well in metal-based batteries.

North Korean leader Kim Jong Un is “seriously preparing” for war as it builds its nuclear weapons arsenal, according to an expert on Korean history.

After decades of international pressure attempting to stop its development of nuclear weapons, North Korea announced during the administration of former President George W. Bush that it was conducting nuclear tests and had weapons. The country now has an arsenal that includes an estimated 35 to 63 warheads, according to the Institute for Science and International Security.

In an interview published by The Financial Times on Thursday, Kookmin University history professor Andrei Lankov said that Kim had been emboldened to build the nuclear arsenal due to Western leaders failing to take advantage of earlier opportunities to pressure the regime, wrongly believing that the nuclear program was not “a realistic threat.”

Android Studio, like so much of Google’s product portfolio, is getting its infusion of AI today at the company’s annual I/O developer conference. Android Studio Hedgehog, the upcoming version of Android Studio currently in the canary release channel, will be the first to add support for the new conversational experience in Android Studio meant to help developers write code and fix bugs and answer more general coding questions.

Built on top of Codey, Google’s new PaLM 2-based foundation model specifically trained for coding, the Studio Bot will roll out to developers in the U.S. first, with a wider rollout expected over time.
