With the help of modern machine learning technology, The Beatles were able to release their song “Now and Then” in late 2023. The song contains vocals recorded from around 50 years ago and a guitar track from 1995, but technological limitations at the time prevented it from seeing the light of day without serious audio issues. Today, after being nominated in November 2024 for two Grammys, “Now and Then” won one for Best Rock Performance.

When the demo was first recorded, John Lennon’s singing and piano were on the same audio track, and separating them was impossible. Fortunately, AI can now do that without much bleed or loss. The surviving Beatles, Paul McCartney and Ringo Starr, were able to complete the song by recording new bass and drum parts and releasing it almost 30 years later.

Sean Ono Lennon, the son of the late Beatle, accepted the trophy in his father’s stead. “Now and Then” was also nominated for Record of the Year but lost to Kendrick Lamar’s “Not Like Us.”

Samsung’s executive chairman Jay Y. Lee has been cleared of criminal charges by South Korea’s second-highest court, Bloomberg reported. Earlier on Monday, the Seoul High Court upheld an earlier decision acquitting Lee of stock manipulation and accounting fraud charges over a 2015 merger. The ruling will allow Lee to focus on Samsung’s mobile and chip businesses, which have seen declining profits over the past couple of years. Yee has consistently denied committing any crimes. 

The prosecution can still appeal to the Korea’s Supreme Court, but that would be unlikely to succeed since no new arguments could be presented, experts say. “It has been a very long time in the investigation and trial of this case,” said Samsung lawyer Kim You Jin in a statement. “We hope that with this verdict, the defendants can now focus on their work.”

Back in 2017, prosecutors accused Lee of manipulating the share price of two Samsung subsidiaries to smooth the way for a merger that allowed him to consolidate his power. In early 2024, however, the court ruled that the prosecutors failed to prove that. “It is hard to say that Lee Jae-yong [aka Jay Y. Lee]… spearheaded the merger, and that the merger was done just for the sake of Lee’s succession,” a judge stated in the ruling.

At the time, the decision was hailed by business groups, but not everyone in the country agreed. “The ruling will free Lee of legal risks, but I am at a loss for words in terms of the country’s economic justice,” Park Ju-geun, head of corporate thinktank Leaders Index, told The Financial Times in February 2024. “This goes totally against all previous court rulings on the merger.”

Lee was originally sentenced to five years in prison in 2017 after being found guilty of bribing public officials over the same merger, but the Supreme Court overturned that decision and ordered the case to be retried. In that retrial, Lee was sentenced to two-and-a-half years of prison time in early 2021, then paroled half a year later (Korea’s former president Park Geun-hye also went to jail for her role in the same affair.) In 2022, Lee was pardoned by South Korean President Yoon Suk Yeol, who was himself recently impeached and charged with insurrection over a martial law attempt.

There’s no two ways about it, there’s a newfound sense of urgency at OpenAI. Two days after releasing o3-mini to the world, the company made a surprise announcement on Sunday evening, revealing Deep Research. The new feature allows ChatGPT to find, analyze and synthesize hundreds of websites and online sources to create reports “at the level of a research analyst.”

On top of the usual text questions, users can upload files, including PDFs and spreadsheets, when prompting ChatGPT in this way. The chatbot will then take “anywhere from 5 to 30 minutes” to compile an answer, a side panel documenting the agent’s progress and citations as it works. “It accomplishes in tens of minutes what would take a human many hours,” OpenAI says of the new feature.

“Our ultimate aspiration is a model that can uncover and discover new knowledge for itself,” said Mark Chen, chief research officer at OpenAI, during the company’s reveal livestream. “It’s core to our [artificial general intelligence] roadmap.”

As far as limitations go, OpenAI says ChatGPT can sometimes hallucinate facts or make incorrect inferences when conducting Deep Research, though “at a notably lower” rate than other current models. Additionally, the agent may sometimes struggle to differentiate between authoritative information and rumors. Users may also notice some formatting errors. “We expect all these issues to quickly improve with more usage and time,” the company notes.

If all of this sounds familiar, it’s because Google’s Advanced suite includes its own Deep Research feature, which not only shares the same name but broadly offers the same set of capabilities as well. One significant difference between the two is that Google offers access to Gemini Advanced through its $20 per month One AI Premium plan. By contrast, you’ll need a $200 per month ChatGPT Pro plan to start using OpenAI’s version of Deep Research today.

“Deep research in ChatGPT is currently very compute intensive,” the company reasons, adding it will limit Pro users to 100 queries per month. “The longer it takes to research a query, the more inference compute is required.”

OpenAI says it’s working on a version of Deep Research powered by a smaller, more cost-effective model. In turn, that will allow the company to offer “significantly higher rate limits.” In the meantime, OpenAI hopes to get the tool in the hands of Plus users “in about a month,” following a round of safety testing. As with most of the company’s other recent releases, European users will need to wait before they can try out the tool for themselves, with Deep Research not yet available to people in the UK, Switzerland and the broader European economic zone.
