Nvidia has released an artificial intelligence (AI)-powered chatbot called Chat with RTX that runs locally on a PC and does not need to connect to the Internet. The GPU maker has been at the forefront of the AI industry since the generative AI boom, with its advanced AI chips powering AI products and services. Nvidia also has an AI platform that provides end-to-end solutions for enterprises. The company is now building its own chatbots, and Chat with RTX is its first offering. The Nvidia chatbot is currently a demo app available for free.

Calling it a personalised AI chatbot, Nvidia released the tool on Tuesday (February 13). Users intending to download the software will need a Windows PC or workstation that runs on an RTX 30 or 40-series GPU with a minimum of 8GB VRAM. Once downloaded, the app can be installed with a few clicks and be used right away.

Since it is a local chatbot, Chat with RTX does not have any knowledge of the outside world. However, users can feed it with their own personal data, such as documents, files, and more, and customise it to run queries on them. One such use case can be feeding it large volumes of work-related documents and then asking it to summarise, analyse, or answer a specific question that could take hours to find manually. Similarly, it can be an effective research tool to skim through multiple studies and papers. It supports text, pdf, doc/docx, and xml file formats. Additionally, the AI bot also accepts YouTube video and playlist URLs and using the transcriptions of the videos, it can answer queries or summarise the video. For this functionality, it will require internet access.

As per the demo video, Chat with RTX essentially is a Web server along with a Python instance that does not contain the information of a large language model (LLM) when it is freshly downloaded. Users can pick between Mistral or Llama 2 models to train it, and then use their own data to run queries. The company states that the chatbot leverages open-source projects such as retrieval-augmented generation (RAG), TensorRT-LLM, and RTX acceleration for its functionality.

According to a report by The Verge, the app is approximately 40GB in size and the Python instance can occupy up to 3GB of RAM. One particular issue pointed out by the publication is that the chatbot creates JSON files inside the folders you ask it to index. So, feeding it your entire document folder or a large parent folder might be troublesome.

YouTube is testing new vertical scroll gestures for its mobile app that might change the way how users navigate through and consume content on the platform, according to claims on social media. The video-streaming platform is said to be testing a change in the outcome of the swipe-up and swipe-down gestures when the fullscreen mode is toggled on the YouTube app. Notably, this development comes after YouTube for Android and iOS was speculated to roll out the ability to control the playback speed of videos more intricately.

At present, swiping up on any video on YouTube’s mobile app toggles the fullscreen mode, while swiping down brings it back to the default view. Additionally, it also allows users to see videos from the suggested, for you, or related tabs by swiping up when the fullscreen view is enabled. The functionality of these gestures are now tipped to be changed.

In a post on X (formerly Twitter), user Tushar Mehta (@thetymonbay) highlighted new vertical swipe gestures that are currently being tested by YouTube. If the proposed changes come to fruition, swiping up on any video will automatically send the user to the next video, instead of minimising to the default view. This is said to work along the same lines as the scroll gestures on YouTube Shorts.

Furthermore, swiping up when the playback controls overlay is on the screen will bring up a scroll window, enabling the user to scroll through the video frame-by-frame. However, this change is said to be in testing and has not been implemented on the current version of the YouTube mobile app.

Despite this change not being official, users on X appeared to not be fond of it. “this is so frustrating. Frustrating enough to drive me to twitter to see if I’m the only one who’s annoyed”, commented one user.

Microsoft on Tuesday laid out an aggressive spending plan to meet demand for its new artificial intelligence services after surpassing Wall Street estimates for fiscal fourth-quarter revenue and profit.

Costs rose sharply as Microsoft built new data centers to support AI, and Chief Financial Officer Amy Hood said on a conference call with analysts the company’s capital expenditures would continue rising each quarter throughout fiscal 2024.

Shares fell about 4 percent in after-hours trade.

Wall Street is looking at how generative AI services may benefit Microsoft, which secured an early lead with investments in OpenAI, owner of the popular ChatGPT service.

Microsoft is weaving AI into its own products, such as the $30 (roughly Rs. 2,460)-a-month “Copilot” assistant for its Microsoft 365 service that can summarize a day’s worth of emails into a quick update. It is also aiming to sell cloud computing services that other firms will use to build AI services.

Microsoft’s results show heavy spending on AI services ahead of commensurate revenue growth.

While its Azure sales growth slightly exceeded market expectations, Microsoft’s quarterly capital expenditures hit the highest single-quarter total since at least its fiscal 2016. The company is battling other cloud providers for a limited supply of chips from Nvidia, whose graphics processing units are essential for creating AI products and services.

CFO Hood told analysts that despite Microsoft’s increased spending in fiscal 2024, operating profit margins would grow slightly after adjusting for the effects of an accounting rule change. “The real focus here is being able to be aggressive in meeting the demand curve,” Hood said.

It will take time to make money, Hood said, noting that Copilot is not ready for general release and any revenues from the product are likely to happen toward the second half of fiscal 2024.

Microsoft forecast Azure revenue growth of 25 percent-26 percent in constant currency for the fiscal first quarter, compared with an estimate of 25.6 percent from Visible Alpha that does not adjust for foreign exchange rates.

For the segment that includes Azure, Microsoft forecast a first-quarter revenue range with a midpoint of $23.45 billion (roughly Rs. 1,92,313 crore). Analysts on average estimated $23.55 billion (roughly Rs. 1,93,133 crore) according to Refinitiv data.

The midpoint of its first-quarter forecast for the segment containing Office was $18.15 billion (roughly Rs. 1,48,839 crore), compared with analysts’ consensus estimate of $18.08 billion (roughly Rs. 1,48,259 crore).

Microsoft’s forecast for its Windows segment had a midpoint of $12.7 billion (roughly Rs. 1,04,145 crore), below analysts’ estimate of $13.14 billion (roughly Rs. 1,07,765 crore).

Revenue in the fiscal fourth quarter that ended June 30 rose to $56.2 billion (roughly Rs. 4,60,924 crore), beating the consensus estimate of $55.5 billion (roughly Rs. 4,55,183 crore) according to Refinitiv. Net income was $2.69 (roughly Rs. 220) per share, above the $2.55 (roughly Rs. 209) average estimate.

Microsoft’s Intelligent Cloud unit, which houses the Azure cloud computing platform, increased its revenue to $24 billion (roughly Rs. 1,96,838 crore) slightly topped expectations according to Refinitiv data.

Azure revenue rose 26 percent, beating a 25.2 percent growth estimate from Visible Alpha.

Microsoft does not break out a precise quarterly revenue figure for Azure, the part of its business best situated to capitalize on booming interest in AI. But Chief Executive Satya Nadella said on a conference call that Azure accounted for more than half of the $110 billion (roughly Rs. 9,02,165 crore) for “Microsoft Cloud” in fiscal 2023, putting Azure sales at $55 billion or more and revealing the size of the business for the first time.

The company is still navigating a PC business slump with sales, including those of its Windows operating system, falling to $13.9 billion (roughly Rs. 1,13,997 crore). The segment with the LinkedIn social network and its Office productivity software increased sales to $18.3 billion (roughly Rs. 1,50,074 crore). Both segments slightly topped the average analyst estimate, according to Refinitiv data.

Capital expenditures jumped to $10.7 billion (roughly Rs. 8,77,507 crore) from $7.8 billion (roughly Rs. 63,966 crore) in the fiscal third quarter, after the company told investors spending would rise as it builds out data centers for AI work.

Microsoft has started integrating AI functionality across its products such as Azure, Microsoft 365, GitHub, and several developer tools.
