Tech Express | August 17, 2026 OpenAI launches GPT-5.6 Multi-Agent V2

1. OpenAI launches GPT-5.6 Multi-Agent V2, boosting speed 16x

OpenAI rolled out blockbuster updates to both ChatGPT and Codex. According to leaked internal messages, ChatGPT received an "epic" performance overhaul: app loading speed surged by 94%, memory usage dropped 41.2%, network requests plunged 98.2%, and conversation-history loading time was slashed by 99.6%.

At the same time, Codex officially launched the GPT-5.6 "Multi-Agent V2" version. The main agent can now automatically delegate subtasks to different models, with each sub-agent independently configurable for its own reasoning intensity. In internal tests, a "monster-level" conversation of 741 rounds weighing 231MB saw its average open time drop from 27.62 seconds to 1.66 seconds. OpenAI president Greg Brockman said the company is moving toward "saying goodbye to manual model selection."

2. Anthropic's Claude hit by major outage

On the evening of August 16, Anthropic's AI assistant Claude suffered a major outage, with users reporting login failures and degraded performance. According to the official status page, the incident began around 21:58 UTC and affected multiple services including claude.ai, Claude Code, and Claude Cowork.

This was another noticeable service disruption for Claude in recent weeks, sparking widespread discussion in the developer community. Fortunately, community reports indicate the outage was short-lived, with services gradually recovering after roughly 36 minutes. For users who rely on Claude for daily development, the brief interruption once again highlighted the risks of depending on a single AI provider.

3. DeepSeek raises API prices

Chinese large-model company DeepSeek has officially raised its API pricing. The company had warned developers on August 6 that a "significant" price increase was coming, without disclosing the exact amount or timing. With the new prices now in effect, the model once known for its extreme affordability is moving away from its ultra-low-price strategy.

Analysts say the price hike reflects a shift in the competitive logic of the large-model industry — as training and inference costs remain high, the low-price land-grab model is becoming unsustainable. JPMorgan also noted in its latest research that the GLM-5.3 upgrade and DeepSeek's price hike are reshaping China's AI landscape, and raised its price targets for Zhipu, MiniMax, and others.

4. Intel's Nova Lake-S powers on, bringing back AVX-512

New Linux kernel logs show that Intel's next-generation flagship desktop processor, Nova Lake-S, has successfully powered on internally and booted on two engineering sample boards — bringing the highly anticipated chip one step closer to launch.

The leaked logs show two engineering samples with 24-core/24-thread and 28-core/28-thread configurations, with base clocks of 3.4GHz and 3.2GHz respectively. More notably, their XSAVE feature lists both expose AVX-512 and APX register save states, signaling that Nova Lake-S could fully restore the AVX-512 instruction set after six years, along with the new APX instructions, to strengthen multi-threaded and compute performance.

5. China-made CXMT DDR5 server memory debuts

China's domestic memory industry hit a new milestone. SINKER, a brand under Jiahe Jinwei, officially launched a DDR5 RDIMM 48GB 5600MT/s server memory using domestic CXMT (ChangXin) chips — the first known 48GB non-binary-capacity server memory made with Chinese-made DRAM.

The product undergoes per-die electrical parameter scanning, leakage detection, and impedance verification from wafer intake, and features a dual ECC architecture combining on-die ECC and external ECC. With a transfer rate of 5600MT/s and over 44.8GB/s of single-module bandwidth, it supports memory-hungry workloads such as VM clusters, in-memory databases, and AI large-model loading.

6. iPhone Ultra faces tight initial supply

Apple's first foldable phone, the iPhone Ultra, is reportedly facing very tight initial supply. Its production capacity is said to be far below that of regular slab iPhones — at a rumored 10 million units, the initial ramp-up by Luxshare and Foxconn would take three to five months, whereas the standard iPhone 17 can produce 5 million units in a single month.

This means the iPhone Ultra will be extremely sought-after at launch, with channel markups potentially enormous. If Apple prices it around 20,000 yuan, first-day resale could reach 30,000 to 50,000 yuan. Based on known details, the iPhone Ultra features a 4:3 wide foldable design with a 7.76-inch inner display, a TSMC 2nm A20 Pro chip, and 12GB of RAM.

7. Pixel 11 spotted alongside mysterious Google wearable

Newly leaked photos show Google's next-generation Pixel 11 phone appearing alongside a mysterious wearable device, fueling speculation about new Google hardware. Based on its appearance, the wearable could be the next-generation Fitbit Charge 7 tracker.

Google has repeatedly been reported to be preparing multiple new hardware products. As the Pixel 11 series nears its launch, leaks around its surrounding ecosystem are growing more frequent. If the mysterious device is indeed a new Fitbit, Google's "phone + wearable" lineup will be further completed.

8. Astronomers discover a new object: the "black hole star"

Astronomers have announced the discovery of a brand-new type of astrophysical object — a "black hole star." The mysterious red dot, dubbed MoM-BH*-1, sits in the early universe and looks like an enormous star, yet produces energy closer to a black hole, shining 100 billion times brighter than a typical star.

Researchers believe it may be a black hole of roughly 100,000 times the Sun's mass, wrapped in a dense cocoon of hydrogen and formed less than 700 million years after the Big Bang. The discovery, enabled by the James Webb Space Telescope, could help explain the mysterious "little red dots" often found in deep-space images.

9. Unitree unveils "Superman" humanoid robot

Unitree Robotics has officially unveiled its new humanoid robot, "Superman." In jumping and sprinting tests, it delivered impressive results: with 0.85-meter legs, it reached a standing vertical jump of 2 meters indoors, beating the human world record of 1.8 meters; on an outdoor track it hit a top speed of 12.66 m/s, also surpassing the human limit of 12.4 m/s.

According to Unitree, the robot's entire development cycle took just over three months, and it is not yet a fully optimized product, leaving room for further iteration. Unitree also introduced the As2-W wheeled-legged robot dog, which supports 16kg of continuous payload and over 30km of no-load range.

10. China launches satellite groups twice in 12 days

China's low-Earth-orbit satellite internet build-out is accelerating. On August 16, a Long March-12 rocket sent the 24th group of low-orbit internet satellites into their preset orbits, a complete success. This was China's second such constellation launch in 12 days, making the "assembly-line" pace of network construction increasingly clear.

Experts note that the two successful launches underscore China's clearly accelerating pace in building its satellite internet constellation, though gaps remain in launchpad efficiency and rocket reusability compared with leading players. As more constellation satellites reach orbit, China's commercial space sector is entering a new phase of dense launches.
