The first European models are expected to be launched later this year, according to the announcements. Nvidia’s technology and partners will provide the AI infrastructure for the project, the chip maker said in a press release. About a dozen model builders and AI consortiums across Europe and the Middle East have teamed up with Nvidia to optimize their AI models using its technology and techniques
The artificial intelligence (AI) startup is handling 780 million queries per month, and that figure is growing over 20% month over month, Srinivas said during an interview conducted at the Bloomberg Tech conference in San Francisco and shared in a video by Bloomberg. Perplexity recorded those figures in May, Srinivas said. If the company can sustain this growth rate, it will be doing a billion queries a week by this time next year, he added. “We still think that same trajectory is possible even now, especially with all the kind of distribution partnerships we are trying to seek and the browser that we’re working on,” Srinivas said
In a move that could potentially reshape how people look at the delivery of consumer and SMB legal services, genAI-driven research platform Perplexity is to provide its Pro subscribers with LegalZoom’s legal help directly within the application.For Artificial Lawyer this is something of a watershed moment, as it’s not just a Google search that might drag up some random bits of legal info, or a ChatGPT prompt to surface something the LLM has perused – it’s an active and deep connection between Perplexity and a bona fide legal information supplier – in this case LegalZoom.As readers know, LegalZoom pioneered the field of providing legally reliable templates and related legal information to consumers and SMBs – often running into challenges from local Bars in the US because of what it did. Yet, here we are now….which takes things to a new level. As the companies explained, the move matters because:. ‘The partnership reflects a broader shift in consumer behaviour as generative AI platforms continue to gain in popularity for information and research needs. Perplexity Pro subscribers will gain access to exclusive offers from LegalZoom, including discounts on legal services and products tailored to individuals and small businesses.LegalZoom will be the provider of legal services for Perplexity Pro users.’. Another way of looking at it would be that as more people turn to LLMs for legal help, then companies that have dominated this consumer area face a challenge. In this case it looks like a ‘if you can’t beat them, join them’ scenario

This collaboration may lead to Perplexity’s AI replacing Google’s Gemini assistant on Galaxy devices, with integrations planned for Samsung’s web browser and Bixby assistant
Two breakthroughs in artificial intelligence (AI) model capabilities can help brands understand and serve their customers at a deeper level.
