Elon Musk’s AI company xAI announced the rollout of the new Grok 4.1 model that it said was “exceptionally capable in creative, emotional, and collaborative interactions”.

Grok 4.1 is based on the same large scale reinforcement learning infrastructure that powered Grok 4, and had a silent rollout between November 1 and 14, according to the company’s blog post.

xAI noted that when compared to the previous production model in traffic, Grok 4.1 was preferred 64.78% of the time. In response to emotional prompts, Grok 4.1 provided longer answers loaded with more melodrama and sympathy/empathy when compared to the previous Grok model’s shorter and more professional responses.

“We are excited to introduce Grok 4.1, which brings significant improvements to the real-world usability of Grok. Our 4.1 model is exceptionally capable in creative, emotional, and collaborative interactions. It is more perceptive to nuanced intent, compelling to speak with, and coherent in personality, while fully retaining the razor-sharp intelligence and reliability of its predecessors,” said xAI in a blog post on November 17.

Grok 4.1 is available to all users on grok.com, X, and the iOS and Android apps.

Apart from the rollout of of Grok across X, the social media platform announced the Chat secure messaging feature on November 15.

X noted that Chat offered end-to-end encrypted chats and file sharing, the ability to edit/delete messages, screenshot blocking and detection features, and no ads or tracking. Voice memos are also set to return, per the official Chat handle on X.

Apple has lost a rising star in its renowned design team, Abidur Chowdhury, an industrial designer who played a role in the development of the recently launched iPhone Air. Mr. Chowdhury, per Bloomberg’s Mark Gurman, has left the tech giant to join an artificial intelligence startup, a move that has reportedly “made waves” internally.

Mr. Chowdhury’s prominence was highlighted when Apple selected him to present the design and features of the iPhone Air in a video for its September launch event. This public-facing role is considered a significant acknowledgment of a designer’s influence within the company. He joined Apple in 2019, around the same time as the departure of iconic design chief Jony Ive.

Mr. Chowdhury, per Gurman’s report, was a key contributor to the development of the iPhone Air, a device that has been praised for its design despite facing weaker-than-expected sales. A follow-up version of the iPhone Air is reportedly in the works for 2027.

Mr. Chowdhury’s departure is part of a larger transition within Apple’s design division, which has seen several veteran designers retire or move to other companies, including Ive’s firm, LoveFrom. This shift comes as the design teams now report directly to CEO Tim Cook, following the recent departure of Chief Operating Officer Jeff Williams, who had been overseeing the group. This move is seen as underscoring the continued importance of design to Apple’s future.

Oppo Find X9 Pro Review: A flagship that finally feels whole

0

The Oppo Find X series is known for its advanced camera system, which has consistently been a standout feature, pushing the boundaries of mobile imaging technology. Extending this legacy, Oppo has launched the Find X9 Pro, a flagship that combines top-tier performance, impressive battery life, and a refined camera system, positioning itself as a compelling choice in the premium segment against competitors like the Google Pixel 10 Pro, and Samsung Galaxy S25 Edge. Now the big question is, can Oppo’s latest flagship truly win over users with its two biggest selling points? Let’s find out.

Design

Oppo has reworked the design this year, and the Find X9 Pro feels cleaner, flatter, and better balanced. At 8.25mm thin, it strikes a solid balance between slimness and a reassuring flagship heft. The flat edges and soft contours improve grip, while the Silk White finish introduces a pearlescent glow that feels luxurious without being showy. The Titanium Charcoal colour option offers a more understated, matte look for those who prefer a stealth finish.

The redesigned camera island now sits flush in the top-left corner and aligns perfectly with the frame. It looks intentional and fixes a practical problem too. Even during landscape gaming or shooting videos, your fingers naturally avoid the lenses.

This year, Oppo also introduces two physical controls, the customisable Snap Key on the left and the refined Quick Button on the right. The Snap Key can be set for functions like screenshots, the voice recorder, translation, the flashlight, or activating AI Mind Space. The Quick Button feels more precise than before and supports double-tap to open the camera, a press to shoot, a long-press for burst photos, and swipe-to-zoom gestures when held sideways.

Durability has jumped significantly. The phone brings IP66, IP68, and IP69 ratings, Gorilla Glass Victus 2 protection, and SGS Five-Star Drop Resistance. For a device that looks this elegant, it’s surprisingly rugged.

Display

The Find X9 Pro features a 6.78-inch AMOLED panel with symmetrical 1.15mm bezels on all sides, the thinnest ever on an Oppo flagship. The near edge-to-edge screen feels expansive without relying on curves, making it ideal for media and gaming.

Brightness is exceptional. With 3,600 nits peak and 1,800 nits full-screen brightness, it stays visible even under harsh sunlight. At night, the panel drops to 1 nit while using 2160Hz PWM dimming, reducing strain for sensitive eyes. The display also supports Dolby Vision, HDR10+, and HDR Vivid, along with TÜV Rheinland Intelligent Eye Care 5.0 certification.

Oppo has upgraded the in-display fingerprint system to a new 3D ultrasonic sensor. It unlocks the phone faster and more reliably, including with wet fingers, and without the bright flash optical scanners use in the dark.

A thoughtful touch here is Vehicle Motion Alerts. The screen displays subtle moving cues along the edges when you’re in a car, reducing motion sickness by aligning what you see with the motion you feel. It’s a small but surprisingly effective addition.

OS and AI

ColorOS 16 feels smoother and more tightly integrated compared to previous versions. The Luminous Rendering Engine sharpens animations, while the Trinity Engine optimizes power and performance at the chip level. Switching between apps feels natural, and even heavy multitasking remains stable.

The Flux Home Screen now allows free resizing of icons and folders, while Aqua Dynamics introduces floating cards that respond fluidly to touch. AI Mind Space acts as a personal knowledge vault and works seamlessly with three-finger capture or the Snap Key. Saved content syncs with Google Gemini, letting you search or ask questions based on what you’ve captured.

Oppo has committed to long-term support too, promising five years of OS updates and six years of security patches. Combined with its AI Writer, AI Recorder, and AI Portrait Glow under the unified AI Hub, the Find X9 Pro feels mature, clean, and far more cohesive.

Performance

The Find X9 Pro is powered by MediaTek’s Dimensity 9500, a 3nm chipset that marks a big leap over the previous Snapdragon-powered X8 Pro. Paired with 16 GB LPDDR5X RAM and 512 GB UFS 4.1 storage, it handles everything with ease, from intensive multitasking to extended gaming. In benchmarks, it scored 3265 in single-core and 9526 in multi-core, alongside an AnTuTu score of 3.37 million, placing it near the top tier of 2025 flagships.

Oppo’s Trinity Engine plays a major role here. Chip-Level Dynamic Frame Sync improves fluency during intense scenes, while the Programmable Scheduler cuts redundant instructions and helps the phone stay efficient under load. Sensor Offload shifts video processing tasks to the chipset, lowering power consumption during 4K HDR recording. The redesigned vapour-chamber cooling system, now 33 percent larger, keeps temperatures stable with its ultra-fine 0.025mm steel mesh structure.

In real-world use, the phone feels effortlessly smooth. Launching heavy apps, editing 4K videos, or switching between multiple windows happens instantly. Gaming performance is stellar, titles like PUBG Mobile and Genshin Impact run at peak frame rates with stable thermals, thanks to Oppo’s Trinity Engine and the redesigned vapor chamber cooling system, which offers 33% better heat dissipation than before.

Compared to the Pixel 10 Pro, which excels at AI-heavy workloads, the Find X9 Pro leans toward sustained graphical and thermal stability. It performs neck and neck with the Galaxy S25 Edge, but with more consistent performance over longer gaming sessions. The AI LinkBoost feature also deserves credit, it keeps network strength stable in low-signal zones, something you’ll appreciate if you travel or game online frequently.

Overall, this is Oppo’s smoothest and most thermally balanced performance package yet, a phone that performs like a flagship should, without breaking a sweat.

Camera

This is where the phone truly comes alive. Oppo’s new Hasselblad Master Camera System combines powerful hardware with a refined computational backbone, and the results show it.

The star of the setup is the 200 MP periscope telephoto camera with a large 1/1.56-inch sensor. The Hasselblad-certified f/2.1 lens uses aerospace-grade glass to minimize stray light, and the floating focus system allows macro photography from just 10 centimeters away. Zoom is excellent across the range, delivering crisp clarity at 3x, 6x, and all the way up to 13.2x lossless zoom. When pushed further, computational enhancements allow up to 120x zoom. The 200MP Hi-Res Mode produces massive 16K UltraHD photos that retain detail even after aggressive cropping.

The main camera is a 50 MP Ultra XDR sensor built with Sony, using the custom LYT-828 chip. With a large 1/1.28-inch size, a bright f/1.5 aperture, and Real-Time Triple Exposure, the camera delivers a claimed 17 stops of dynamic range. In real use, it maintains excellent balance across shadows and highlights without resorting to artificial brightening. The 50 MP ultrawide camera includes autofocus and supports close-focus macro shots from 3.5cm away.

Colours see a major improvement through the True Color Camera, a dedicated 9-channel multispectral sensor with two million spectral pixels. It measures colour across the frame, giving the Find X9 Pro more accurate tones and better white-balance consistency, especially in difficult lighting.

Photos are saved at 50 MP by default across all three rear cameras, giving everyday shots 8K-level clarity. When needed, the system smartly adapts to 25 MP or 12 MP to control noise and maintain quality.

The LUMO Image Engine transforms the imaging pipeline with parallel computing. Instead of sequential processing, the ISP, NPU, CPU, and GPU work together on each frame, improving clarity, cutting noise, and reducing power usage. The Lightning Snap Engine handles motion better, while HyperTone ensures natural contrast and avoids overprocessing.

Creative tools round out the system. The Find X9 Pro debuts 4K Motion Photo, allowing you to extract high-resolution frames from motion footage, while features like Motion Photo Collage, 4K Slow-Mo, enhanced XPAN Mode, and direct Instagram sharing make it easy to experiment. Master Mode returns for manual shooting with RAW MAX and JPEG MAX options, and the new dual-flash system introduces nostalgic CCD-inspired looks with Warm Flash and Cold Flash film simulations.

The 50 MP selfie camera continues the high-resolution approach and offers 4K 60fps Dolby Vision video, producing detailed and natural self-portraits in most lighting.

Battery

Battery life is one of the biggest upgrades this year. The Find X9 Pro houses a 7,500 mAh third-generation silicon-carbon battery, which increases capacity without adding thickness. With moderate usage, the phone comfortably lasts up to two full days, and even under heavier loads, it still stretches well into the next day. Oppo says the battery retains up to 80 percent capacity after five years, thanks to its higher silicon content and optimised material design.

Charging is fast and flexible with 80W SUPERVOOC wired charging and 50W AIRVOOC wireless charging. It also supports up to 55W USB-PD fast charging and offers 10W reverse wireless charging for accessories. A short 20-minute charge brings the battery back to a healthy level, removing any meaningful battery anxiety.

Verdict

The Oppo Find X9 Pro feels like a flagship built with intention. The design is refined and durable, the display is bright and comfortable, ColorOS 16 is polished and fluid, and performance remains consistently strong. The silicon-carbon battery brings class-leading endurance, and the camera system, powered by Hasselblad tuning, the True Color Camera, 50 MP default shooting, Ultra XDR processing, and the LUMO Image Engine, is easily Oppo’s most complete to date.

The Find X9 Pro may not have the ecosystem pull of Apple or Google, but it delivers one of the most balanced, personal, and thoughtfully engineered Android experiences of 2025. It sets a new benchmark for Oppo and stands out as a flagship that finally feels whole. Oppo Find X9 Pro costs ₹1,09,999 in India.

Amazon is looking to raise about $12 billion from the corporate bond market in its first such deal in U.S. dollars in about three years, Bloomberg News reported on Monday, citing people familiar with the matter.

The e-commerce giant filed for a six-part bond sale earlier in the day without disclosing a size, a regulatory filing showed.

Amazon did not immediately respond to a Reuters request for comment.

As artificial intelligence workloads grow in scale, big technology firms are turning to large-scale debt sales to fund expansion plans that cost tens of billions of dollars.

Last month, Meta Platforms announced its biggest bond sale of up to $30 billion, while cloud infrastructure and software maker Oracle is also reportedly looking to raise $15 billion in bond sales.

BofA says AI is boosting bankers’ productivity, revenue

Bank of America plans to spend billions of dollars on technologies such as artificial intelligence to boost bankers’ productivity and bring in more revenue, its chief technology and information officer said on Monday.

BofA plans to allocate $4 billion into new technology capabilities from its $13 billion tech budget, the company told investors earlier this month. It plans to use AI more widely across all its businesses.

“How many clients can a given relationship banker cover if you’re able to actually automate that process using AI,” such as preparing client briefing documents before meetings, Hari Gopalkrishnan, who took over the role at BofA in July, said at the Reuters Momentum AI Finance conference in New York. “You now can have a banker cover 50 clients instead of 15. And that’s exactly what we’re seeing in the real world.” In wealth management, the second-biggest U.S. lender sends AI-generated market information to its financial advisers, combined with data on clients’ portfolios, so that bankers can better tailor their investment advice, he said.

The bank’s 18,000 developers have been using AI agents for the last year, and observed “significant gains” in productivity to automate or speed up mundane tasks, including streamlining some software tests by 90%.

“Our teams are looking at growth, and we’re in the process of strategic planning for the next three years, and you see much more aggressive objectives,” Gopalkrishnan said. “These tools are now taking flight.” Earlier this year, larger rival JPMorgan Chase said AI tools enabled it to boost sales to wealthy clients and manage scores of requests during April’s market rout. Goldman Sachs is rolling out a generative AI assistant to its bankers, traders and asset managers, while Morgan Stanley developed a chatbot for its financial advisers with OpenAI.

BofA’s virtual assistant, Erica, has done work for customers that would have otherwise required 11,000 employees, he said, including routine requests like ordering checks or disputing transactions.

The chatbot was launched in 2018 and has since logged three billion client interactions. Its more advanced applications include predictive data and tools for budgeting and investing.

BofA has invested heavily in technology in recent years. It has more than 59 million digital users and its patent filings exceed 7,800.

When asked about potential job losses from AI, Gopalkrishnan said BofA is focused on training its 213,000 employees to better use AI to reduce mundane tasks so they can focus on bringing in more business.

“The reskilling, along with the leverage to be able to apply a much broader revenue opportunity, has served us very well,” Gopalkrishnan said. That view contrasts with Wells Fargo CEO Charlie Scharf’s view that AI will drive headcount reductions.

Alphabet shares hit record after Berkshire makes rare tech bet with $4.9 billion stake

0

Alphabet shares rallied nearly 6% to a record high on Monday after Berkshire Hathaway’s new stake provided an endorsement of the tech giant’s artificial intelligence efforts amid heightened worries over a looming bubble.

The purchase of 17.85 million Alphabet shares, worth about $4.93 billion as of close on Friday, is one of the final major investments by the conglomerate under Warren Buffett and marks a rare foray into the industry by tech-averse Berkshire.

The billionaire investor has long compared Apple, Berkshire’s largest holding, to a consumer products company.

“The stake purchase of a tech company may represent a different type of mentality at Berkshire, though it’s not a total departure from its value-investing model,” said Steve Sosnick, chief strategist at Interactive Brokers.

The vote of confidence comes as broader sentiment on tech has turned cautious, with several business leaders and experts warning that the AI frenzy driving up tech stock prices has detached valuations from fundamentals and that returns from hundreds of billions in data-center spending remain uncertain.

The Roundhill Magnificent 7 ETF, which tracks the biggest tech stocks such as Nvidia, Microsoft and Alphabet, has been little changed since September, after outperforming the benchmark S&P 500 for much of the year.

Still, Alphabet has been an outlier, with its shares rising nearly 14% so far in the December quarter to make it the year’s best-performing “Magnificent Seven” member with a 46% gain.

The company also trades at a lower multiple, at about 25 times 12-month-forward earnings estimates, compared with Microsoft’s 29 times and nearly 30 for Wall Street darling Nvidia, according to LSEG data.

“Alphabet fits the value-investing theme better than some of the other names that are leading the AI charge right now,” Sosnick said.

Several analysts say Alphabet has a leading position in AI due to its growing infrastructure investments, strong early adoption of AI search tools and a massive ad business that can fund its data-center spending spree.

“The move validates Google’s strong fundamentals and provides Berkshire exposure to a leading AI provider through Google Cloud and Gemini expansion,” said CFRA analyst Angel Zino, adding that Alphabet’s cash flow and valuation likely gave the conglomerate “more comfort” in its decision.

Investors piled into the stock last month, after earnings showed AI investment was turning Google Cloud, once an also-ran, into a key growth engine.

Buying Alphabet shares would also address Buffett and the late Vice Chairman Charlie Munger’s long-standing regret over missing Google early, just before the “Oracle of Omaha” readies to pass on the CEO role to Greg Abel at the end of 2025.

It was unclear if the Google purchase was made by Buffett, portfolio managers Todd Combs or Ted Weschler, or Abel, though Buffett typically oversees Berkshire’s largest investments.

Based on early trading, Alphabet was set to add around $180 billion to its market value, if the gains hold.

Shares often jump when Berkshire reveals new positions, thanks to Buffett’s perceived seal of approval.

Berkshire’s move disclosed in a filing on Friday also drew interest from retail traders, pushing Alphabet into the top-three trending stocks on investor platform Stocktwits.

Overall, Berkshire continued to be a net seller of stocks in the September quarter, further trimming its position in Apple and Bank of America to swell its cash pile to a record $381.7 billion.

Some investors see Berkshire’s cash reserve buildup as a sign that Buffett believes valuations are too high.

The company’s equity portfolio remains heavily tilted towards financial services, which accounted for 36.6% of the holdings as of September, according to Morningstar.

Data analytics firm Databricks is in talks to raise funds at a valuation of more than $130 billion, about 30% higher than its last financing round two months ago, The Information reported on Monday, citing two people familiar with the discussion.

The company declined to comment on the report.

Databricks has not signed a term sheet with any investment firms, the report added.

Reuters could not immediately confirm the report.

In September, the San Francisco-based company closed a $1-billion-funding round that valued it at $100 billion, making it one of the world’s most valuable private companies.

At the time, Databricks said it was on track to hit $4 billion in annualized revenue, driven by booming demand for its artificial intelligence products. The company planned to use the proceeds to accelerate its AI strategy, expand products, launch an operational database category and pursue AI acquisitions and research.

Founded in 2013, Databricks offers a platform that helps users ingest, analyze and build AI applications. The company has long been viewed as a leading candidate to go public and has received numerous investor inquiries.

Databricks has about 15,000 customers, including payments firm Block, energy giant Shell and electric vehicle maker Rivian.
