We integrate this model in a planning loop, where conditioning and classifier guidance let us softly break the symmetry for specific tasks as needed.

In this paper, we set out to answer the question on which is better: neural network quantization or pruning? By answering this question, we hope to inform design decisions made on neural network hardware going forward. We provide an extensive comparison between the two techniques for compressing deep neural networks.

SoftBank CEO Masayoshi Son (left) and OpenAI CEO Sam Altman attend an event in Tokyo in February 2025. SoftBank's investment gain on OpenAI stood at an estimated $19.8 billion as of December. SoftBank Group sprang back to a quarterly profit after investment gains from OpenAI neared $20 billion, a promising start for one of CEO Masayoshi Son's signature gambles alongside ByteDance and Alibaba Group Holding. The Tokyo-based company has invested about $34.6 billion in OpenAI, accumulating an 11% stake as of December, and has been in talks to invest as much as $30 billion more in a round that would value the startup at about $750 billion to $830 billion.

High-altitude platforms could help connect over 2 billion people around the world who are still offline. Today, an estimated 2.2 billion people But that number could drop this year, thanks to tests of stratospheric airships, uncrewed aircraft, and other high-altitude platforms for internet delivery. Even with nearly 10,000 active Starlink satellites in orbit and the OneWeb constellation of 650 satellites, solid internet coverage is not a given across vast swathes of the planet. One of the most prominent efforts to plug the connectivity gap was Google X's Loon project . Launched in 2011, it aimed to deliver access using high-altitude balloons stationed above predetermined spots on Earth. But the project faced literal headwinds--the Loons kept drifting away and new ones had to be released constantly, making the venture economically unfeasible.

Tests conducted by the Guardian show that GPT-5.2 sourced some of its info from the AI-generated online encyclopedia from Elon Musk's xAI. OpenAI may have called GPT-5.2 its most advanced frontier model for professional work, but tests conducted by the cast doubt on its credibility. According to the report, OpenAI's GPT-5.2 model cited Grokipedia, the online encyclopedia powered by xAI, when it came to specific, but controversial topics related to Iran or the Holocaust. As seen in the's report, ChatGPT used Grokipedia as a source for claims about the Iranian government being tied to telecommunications company MTN-Irancell and questions related to Richard Evans, a British historian who served as an expert witness during a libel trial for Holocaust denier David Irving. However, the noted ChatGPT didn't use Grokipedia when it came to a prompt asking about media bias against Donald Trump and other controversial topics. A study done by US researchers also showed that the AI-generated encyclopedia cited questionable and problematic sources.

Apple's Siri AI will be powered by Gemini How to claim Verizon's $20 credit for Wednesday's service outage It isn't applied automatically, because of course it isn't. Verizon is offering a very small after Wednesday's massive outage, which drew more than 1.5 million reports on Downdetector and lasted hours.
