DeepSeek has updated its model on the app, leading to speculation that V4 might be quietly released. This is because the knowledge expiration date is May 2025, and the model itself supports a context window of 1 million tokens. These parameters clearly do not match the last released version, V3.2. However, it's possible that they simply updated the System Prompt first.

I tried out the new version of Deep Research based on GPT-5.2 on ChatGPT. Besides the model update, there are also many changes to the overall interface and the corresponding agent strategies. See the example below 👇

Has xAI been hacked? Are a group of people who left xAI going to work on something new together?

I left xAI. Building something new with others that left xAI. We're hiring :)

I haven't used the Deep Research feature in a long time because the models I was using before seemed to be from the O3 era, so I've been barely using Pro models as substitutes. Now that I've switched to version 5.2, it's necessary to pick it up again.

Deep research in ChatGPT is now powered by GPT-5.2. Rolling out starting today with more improvements.

*My Great World* There's a subway station in Singapore called "Great World." As a Shanghainese, seeing this name felt particularly familiar. A quick look into its origins revealed a close connection. Great World in Singapore was originally built in the 1920s and later acquired and operated by the Shaw Brothers Group. This is shown on Shaw Brothers' official website (shaw.sg/amusementparks），他们很坦诚地写道：它是仿照上海的游乐园建造的（modelled after the ones in Shanghai). This "reproduction" isn't accidental; it reflects the Shaw family's pioneering history in Southeast Asia. The family started with the textile business in Shanghai, accumulating their initial wealth. In the 1920s, Runme Shaw took his capital south to Singapore and founded the Shaw Organization. Later, his brother Run Run Shaw joined. The brothers started from scratch in Southeast Asia, building an independent cinema chain and making a thriving film distribution business. It wasn't until 1957 that Run Run Shaw moved to Hong Kong and founded Shaw Brothers Studio, ushering in the era of "Shaw Brothers films," which is more familiar to everyone today. Although they were two independent companies, they were essentially connected. In Singapore at that time, three "worlds" coexisted: Great World, New World, and Happy World. In 1966, Happy World was renamed Gay World. This name, viewed today, has an unexpectedly avant-garde feel. Compared to this interlude in Southeast Asia, Shanghai's Great World was the true "original." My story with it began in the 1990s. Back then, Shanghai's Great World was still a fashionable entertainment destination. And in that era, the most fashionable sound was undoubtedly the saxophone. With the popularity of the TV series "I Have a Date with Spring," its melody filled the streets and alleys. Once, when I went there with my mother, we happened to see that they were offering saxophone lessons. Perhaps recalling how I was often assigned to lead the recorder performances at school, my mother felt this musical talent shouldn't be wasted. Probably wanting me to have a skill to rely on, she immediately decided to enroll me in a music school. Thus, for those few years, the Great World amusement park was no longer a distorted mirror or a circus for tourists. Each time, carrying my instrument, I would skillfully slip through the back entrance, avoiding the noise of the main gate. Looking back, that familiar feeling of entering from the back of the amusement park has become a more profound memory than the learning itself. Now, the Great World in Singapore has long been demolished, and the Great World in Shanghai has experienced many ups and downs. The saxophone that accompanied me through my university orchestra has been dormant for over a decade. We can't know if the Shaw Brothers' departure was a spur-of-the-moment decision, just as my mother's decision to send me to learn an instrument was an investment with an unpredictable outcome. But looking back, it was precisely these uncertain moments that ultimately changed the history of a family and left a unique memory in my ordinary life. At that time, I did not realize that it was this very instrument in my hand that would later unfold such a rich and real "big world" for me in this amusement park.

The entire industry is questioning Apple's progress in AI, but the Mac Mini is widely recognized as the top choice for beginners in AI.

Regardless of his motivations, Vitalik's commitment to the Rollup-centric approach since 2020 remains unchanged, and he has objectively achieved a highly leveraged strategic outcome: by building a competitive L2 market, he has substantially externalized the costs of scaling R&D. EF does not need to directly invest huge sums of money; simply by setting standards, it has guided more than 10 L2 teams to independently bear all engineering and operational costs. Although EF delivers underlying support such as EIP-4844, the most expensive execution layer R&D expenditures and trial-and-error risks in scaling have been shared by the L2 track. This strategic decoupling allows Ethereum to shed outdated technical narratives at any time, preserving maximum flexibility for protocol evolution without having to pay for any single execution path.

@VitalikButerin

There have recently been some discussions on the ongoing role of L2s in the Ethereum ecosystem, especially in the face of two facts: * L2s' progress to stage 2 (and, secondarily, on interop) has been far slower and more difficult than originally expected * L1 itself is scaling,
