Twitter CEO Elon Musk has bought around 10,000 graphics cards and is hiring AI experts to build a ChatGPT competitor within Twitter, Insider reports.

That’s despite the billionaire CEO repeatedly voicing concerns over AI chatbots like ChatGPT, and even signing an open letter calling for a six-month moratorium on developing AIs more advanced than OpenAI’s GPT-4.

Training a large language model like OpenAI’s highly popular AI chatbot takes a lot of computational power, which means Musk had to dig deep in his sizeable pockets — tens of millions of dollars, according to Insider — to finance the project.

The object’s gravity and velocity, the study suggested, would have ignited the gas and left a blazing trail of stars in its wake. This exciting discovery would mark the first observation of a rogue supermassive black hole — objects that are theorized to roam the universe after being ejected from their host galaxy, possibly due to collisions with other black holes.

Now, new research hints at a more mundane explanation.

The new study, published in the journal Astronomy & Astrophysics (opens in new tab), suggests that the weirdly thin streak might simply be a flat galaxy viewed on its edge, like the rim of a plate. Unlike the Milky Way, this supposed galaxy would not have a bulge of stars at its center but would be totally flat — a relatively common type of galaxy called a thin or flat galaxy.

Lurking in the darkness of space, black holes are notorious for shredding stars that venture too close, and then gobbling them up. But astronomers have had only a rudimentary understanding of that dramatic process.

A new study sheds some light. Astronomers have spotted streams of star matter that came full circle around black holes and bumped into themselves. Such collisions were long theorized, but the new observations for the first time provide a direct look at the early stages of disk-forming around black holes.

Unlike other businesses pushing clean nuclear energy, Helion is working on a “pulsed non-ignition fusion system.”

Microsoft Corporation has placed a big bet on Helion by agreeing to purchase power generated by its nuclear fusion process. Helion is also backed by Sam Altman, the OpenAI CEO with whom Microsoft is spearheading the artificial intelligence (AI) race.

Nuclear fusion is the holy grail of clean energy as it promises the generation of power without the emission of carbon or hassles of radioactive nuclear waste.

Google announced it is rolling out generative AI to its core search engine.

Shortly after Google made several AI-related announcements at its annual developers conference, its parent company Alphabet’s stock shot up by 5% on Wednesday and reportedly made gains of $56 billion to its market value.

Kicking off the conference, saying, “As you may have heard, AI is having a very busy year. So we have lots to talk about,” CEO Sundar Pichai announced that the company is adding Search Generative Experience (SGE) to its search engine by way of AI snapshots. Those who opt for SGE will see an AI-powered snapshot of key information to consider, with links to dig deeper.

MIT researchers developed a technique that captures images of an object from various angles and converts its surface into a virtual sensor that captures reflections.

Imagine seeing around corners or peeking beyond obstacles that once blocked your view. It’s like having X-ray vision. It might now be possible thanks to new research.

A group of brilliant researchers from MIT and Rice University unveiled an incredible computer vision technology that can change how we see the world. We could soon live in a world where shiny objects become extraordinary “cameras” that let us view our surroundings through their unique lenses.

Microsoft will also contribute its algorithm knowledge to make Builder.ai’s Natasha, an AI assistant, sound more human.

Microsoft Corporation has invested an undisclosed amount in Builder.ai, a no-code builder startup, as it looks to diversify its bets in the artificial intelligence (AI) game. Builder.ai lets users with no technical knowledge or experience in coding build their own apps and manage them.

Microsoft is already ahead in the AI game thanks to its partnership with OpenAI, the maker of the popular chatbot ChatGPT.
