1. Tencent launches Yuanbao Search on its 28th birthday, with ads kept in their own block

November 11 marks Tencent's 28th anniversary, and the company used the day to officially launch Yuanbao Search, a new AI search product. Users can reach it directly at so.qq.com in a browser, or upgrade QQ Browser to the latest version and switch the engine setting to Yuanbao Search.

According to Tencent, the service is built on the underlying capabilities of the Yuanbao large model and rebuilds the entire chain from intent understanding and content retrieval to result ranking and answer generation. It indexes at the hundred-billion scale, covering the open web as well as Tencent ecosystem content such as official accounts and video accounts, plus academic literature, and it has connected 157 authoritative sources, with results prioritizing official institutions and official sources.

On advertising, Yuanbao Search sets ads in a separate module labeled "related ads" that users can collapse in one tap. It accepts typed, voice and photo queries, summarizes results with AI first, and lets users keep asking follow-up questions based on the generated answer. Tencent says the product will keep improving through a recursive self-evolution mechanism; it had previously been opened to business customers as an API.

2. User's own writing flagged as unlabeled AI content: court orders platform to restore it

A court case disclosed in China this week gave an answer to a growing problem: what happens when a platform's algorithm wrongly labels a user's original writing as unlabeled AI-generated content and punishes them for it. Beijing Internet Court heard a dispute over a network service contract, according to a report by China Media Group's China National Radio.

The user, identified as Xiao Tang, posted a piece of text to share his own work, but the platform determined it "contained AI-generated content without labeling" and responded by hiding the content and muting the account for one day. Xiao Tang maintained the text was entirely his own, appealed unsuccessfully, and then sued.

The platform argued that the content had been flagged by both machine identification and manual review, and said it had no obligation to explain the specific determination mechanism because the algorithm involves technical secrets and algorithm logic. The judge noted that the text was improvised writing, making it hard to demand a full draft or source file proving the entire creative process, but held that once a platform concludes content is AI-generated, it should reasonably present evidence or explain the algorithmic tools, computation process and review results it controls.

The court ruled that the platform does have the right under its user agreement to review and handle AI-generated content, but that such handling must have a reasonable basis, and it cannot make users bear the consequences of a violation based on an algorithm's output alone. Because the defendant failed to offer an adequate explanation, the court found its handling lacked factual basis and constituted breach of contract, ordering the platform to unhide the content and delete the related backend records.

3. Microsoft's Auto SR arrives on Xbox handhelds, works on battery and hits 120fps

Microsoft announced on November 10 that Automatic Super Resolution (Auto SR), its upscaling technology aimed at Nvidia's DLSS, is rolling out to the Xbox Ally X, the Xbox Ally X20 and select Windows Copilot+ PCs, along with several new features. Microsoft began testing Auto SR on the Xbox Ally X in April, but at the time it only worked while the handheld was docked.

The full release lifts those limits: Auto SR now works in handheld mode while running on battery, and it supports games running at 1080p. Microsoft cautions that handheld play at 1080p "may not be as optimal as other configurations," but says visual improvements will be noticeable, "especially in older games."

Framerates are the other change. Auto SR was previously limited to roughly 60 to 75fps, and a new Auto SR Performance mode raises the ceiling to 120fps. Microsoft says Performance mode and new Auto HDR compatibility will arrive through Windows updates.

4. Spotify gives its AI DJ new voices, personalities and a quieter mode

Spotify announced an upgrade to its AI DJ on November 10. The feature, which launched in 2023, is used by more than 94 million Premium listeners and remains one of Spotify's most popular AI tools. With the update, paying users can customize the DJ much like an AI assistant, choosing between different voices and personalities.

There are seven English voices, spanning British, American, Irish, Australian and Indian accents, plus two new Spanish voices. Each has its own character: among the three American options, Casey is laid-back and warm, Tess is direct with an edge, and Lane carries a Southern accent with youthful energy, while the Spanish voices are Nico, described as more down-to-earth, and Fabi, more witty and friendly. The original "X" voice stays, but Fabi and Nico replace the earlier Livi as the only Spanish voices available.

The other change targets complaints about chatter: users can now switch off commentary between songs, keeping only brief acknowledgements when the DJ starts and when it is turned off. Spotify says that lets people use the DJ in moments when they might have reached for a playlist instead, such as hosting a party where they want background music without the talk. The new voices began rolling out on November 10 in the more than 95 markets where DJ is already supported.

5. AMD details Zen 6: 12 cores per CCD and 144MB of X3D cache

AMD disclosed details of its Zen 6 architecture during a technical presentation on its EPYC Venice server processors. The company has not announced consumer Ryzen parts yet, but since the server architecture carries over to desktop, some of the Zen 6 Ryzen specifications can be inferred.

The core change is that each CCD moves from 8 cores to 12, while shared L3 cache rises from 32MB to 48MB, a 50 percent increase on both counts, with per-core cache still at 4MB. On a 12-core CCD design, a desktop Ryzen chip could reach 24 cores. That matters for gaming: today's 12-core Ryzen parts need two CCDs, and cross-CCD communication adds latency, whereas Zen 6 can fit 12 cores on a single CCD with all of them sharing one L3 cache.

The X3D lineup benefits too. Current dual-CCD X3D models need extra scheduling logic to steer games onto the CCD with 3D V-Cache, complexity that a single 12-core CCD with a large shared cache largely removes. AMD already uses a comparable layout on EPYC Venice-X, pairing 48MB of native L3 with 96MB of 3D V-Cache for 144MB per CCD, versus 96MB per CCD on current X3D chips. AMD's presentation also showed Zen 6c delivering roughly 27 percent average IPC gains in AI and server workloads, though the company noted that figure does not represent gaming performance.

6. Samsung to spend about 99.2 billion yuan on EUV tools in push below 10nm DRAM

With ASML warning of shortages in extreme ultraviolet lithography equipment, the world's leading memory makers are scrambling to lock in deliveries, and Samsung Electronics is moving most aggressively. According to reports, Samsung's investment in EUV lithography tools ordered from ASML could reach a ceiling of 20 trillion Korean won, roughly 99.2 billion yuan.

The logic behind the spending is that advanced memory scaling is nearing physical limits. As DRAM moves to the 1β node and below, circuit spacing shrinks to the low teens of nanometers, forcing traditional deep ultraviolet lithography to stitch patterns together with multiple exposures, which accumulates overlay error until yields can no longer support mass production. EUV's 13.5-nanometer wavelength can define fine patterns in a single exposure and is seen as the only way to keep advanced nodes manufacturable.

On capacity, Samsung is upgrading its Pyeongtaek P4 fab with a plan to add an HBM4 single-crystal DRAM line, while expansion of P5 continues, with its first fab expected to start production in 2028; lithography equipment has already been ordered ahead of the cleanroom's completion in the first half of 2027. Samsung also aims to mass-produce 1D DRAM in 2027 and reach the sub-10nm 0a DRAM stage in 2028, when it would introduce high-NA EUV, and it is evaluating using that equipment in only one or two critical layers to balance cost and yield.

7. Apple's first touchscreen MacBook Pro draws complaints of eye strain and headaches

Apple's first MacBook Pro with a touchscreen, already criticized by a wave of prominent tech reviewers over awkward touch controls, is now facing a new controversy. AppleInsider reported that a number of buyers say they experienced eye strain, headaches and other discomfort after using the new machine, which has a PROLED XDR display, for long periods.

Citing Apple's internal after-sales channels, AppleInsider said Genius Bars at multiple Apple Store locations have received several related complaints, and that authorized resellers have also seen a slight rise in return rates for the model. After teardown testing, the outlet concluded the root cause is the pulse-width modulation (PWM) dimming used by the display, which adjusts brightness by rapidly switching the light-emitting units on and off; even when the flicker is invisible to the eye, it can still bother users sensitive to high-frequency flicker.

The touchscreen MacBook Pro is now on sale in markets around the world, with the China version starting at 22,999 yuan. The report also noted that the touch interaction the company highlighted in its marketing has not kept pace with real-world use.

8. OPPO A7 Ultra tipped for December with a 12,000mAh battery

OPPO's A7 Ultra is expected to launch around December with ultra-long battery life as its selling point and a battery in the 12,000mAh range, according to tipster Digital Chat Station. Based on earlier regulatory filings, it should be the new model certified by China's industry ministry under the model number PNC110, supporting 5G, Wi-Fi and Bluetooth, with a rated capacity of 11,640mAh and a typical capacity of about 11,900mAh.

If accurate, it would be the largest-battery phone OPPO has built and among the biggest in the industry, stretching charging cycles for heavy users, outdoor trips and backup phones for elderly family members. It adopts a wide rectangular camera module, in keeping with the A series' practical positioning.

Notably, after Honor introduced phones with five-figure milliamp-hour batteries, the tipster says OPPO, vivo and Xiaomi are all following with similar models. For reference, the previous model in the line, the OPPO A7 Pro, went on sale in September starting at 2,199 yuan with an 8,000mAh battery, 45W wired charging and 10W reverse wired charging, passing 15 military-standard tests with IP69K, IP69, IP68 and IP66 dust and water resistance; OPPO said it still works after repeated 1.2-meter drops.

9. AI becomes a Singles' Day storefront as JD's shopping assistant draws nearly 80 million users

China's Singles' Day shopping festival has brought an AI shopping boom this year, from chatbots helping people pick products to hot sales of AI toys, robots and computing power packages, Reuters reported on November 11. Whether that enthusiasm can lift overall consumption, however, remains uncertain against weak domestic spending and fierce e-commerce competition.

Alibaba's Taobao and Tmall have rolled out AI product search, virtual try-on and discount recommendations, while JD said its AI shopping assistant, Jingdong Dongdong, drew nearly 80 million users seeking shopping advice during this year's festival, more than triple last year's figure. Data from e-commerce research firm WPIC Marketing + Technologies shows that about 5 percent of transactions on short-video platform Douyin in October were completed through links provided by AI chatbots, a share above 20 percent in categories such as health supplements where shoppers compare carefully.

AI products themselves were also a sales highlight. Alibaba said sales of AI toys on its platforms passed 100 million yuan within a year of the category's launch, and sales of AI companion robots in the second half of October rose nearly fivefold year on year. Tmall data shows sales of AI token packages grew more than 700 percent between October 15 and November 5, and livestreaming host Li Jiaqi sold 100,000 monthly memberships for Alibaba's QwenWork in half an hour in his first AI product pitch. Still, third-party platform Syntun data shows Singles' Day sales rose just 2.4 percent from October 7 to 31, and Ben Cavender, managing director of China Market Research Group, cautioned that AI shopping tools affect brands unevenly, with some potentially hurt if they stop appearing in AI search results.

10. Gravity might seal off time travel, but the new model has an instability problem

If you ever do travel back in time, you absolutely must not hunt down your grandfather before he has a chance to have children, because that would undo your own existence and with it the trip that let you kill him. Stephen Hawking proposed his chronology protection conjecture in 1992, arguing that the laws of physics do not allow closed timelike curves to appear, but physicists have yet to establish what mechanism would enforce it.

Two physicists at the University of New Hampshire, Moustafa Ismail and David Mattingly, asked whether gravity itself might hold the answer. Their approach switches frameworks: in general relativity, spacetime's metric and its connection are tied together, while in metric-affine gravity that relationship is loosened so the two can operate more independently, which gave the researchers room to work. They built a model in which spacetime has a built-in direction of time, so that under the right conditions time always moves forward along any path a traveler could take, making a loop back into the past impossible. They named it Metric-Affine Gravity Imposing Chronology, or MAGIC.

The catch is the cost. In general relativity gravity can fluctuate in two ways, corresponding to the two ways gravitational waves stretch and squeeze space; MAGIC introduces a third, the scalar mode. On the cosmological background the researchers studied, that scalar mode suffers a gradient instability: disturbances do not propagate as stable waves but grow exponentially, with shorter wavelengths growing faster, which means MAGIC cannot yet provide a stable description of the universe. The work also establishes chronology protection only locally, requiring an additional assumption about the overall structure of spacetime. The research is published in Physical Review D, and the authors describe stabilizing the scalar mode as the natural next step.
