OpenAI admits it is developing ChatGPT text watermarks, but faces challenges

On August 5, the Wall Street Journal reported that OpenAI has developed a tool that can recognize ChatGPT-generated text with high accuracy, but it has not yet been released. In response, OpenAI admitted that it is researching text watermarking technology, but said that this technology still has many challenges.

With text watermarking, OpenAI will focus only on detecting text from ChatGPT, not text from other companies’ models. It will do this by making slight changes to the way ChatGPT selects words, essentially creating an invisible watermark in the text that can later be detected by a separate tool.

OpenAI said that text watermarking is one of the solutions they are exploring, including classifiers and metadata, which are designed to determine the source of the text. Although text watermarking technology works well in some cases, it is less effective when faced with tampering such as translation, rewriting, or inserting special characters. In addition, the technology may have a disproportionate impact on certain groups, such as non-native English speakers.

OpenAI said that due to these complex factors and their potential impact on the entire ecosystem, OpenAI said it would carefully advance the research of text tracing technology and give priority to authentication tools for audiovisual content. (Source: IT Home)

Tesla's Texas supercomputing cluster is named "Cortex" and has 100,000 Nvidia chips

Musk revealed the name of the cluster on August 4 after touring the recently built Texas supercomputing cluster over the weekend.

Musk wrote on X that the supercomputing cluster at the Texas Gigafactory is named "Cortex," noting that he had just completed a walkthrough of the new facility. "Cortex" has about 100,000 Nvidia H100 and H200 chips, which are used to train neural networks for fully autonomous driving (FSD) and the humanoid robot Optimus.

Musk also previously detailed the huge cooling needs of the Cortex supercomputing cluster, explaining that the cluster will require about 130 MW of electricity this year and is expected to exceed 500 MW in the next 18 months. To this end, Tesla installed huge fans and four water tanks in the computer center for cooling.

Musk estimated in June that Tesla's spending on Nvidia chips this year could reach $3 billion to $4 billion, accounting for half of the company's total AI-related spending of $10 billion, with the remaining funds going to internally developed AI inference computers, vehicle sensors and Dojo supercomputers.

Gurman: Apple iPhone 16 series phones are not affected by the delay of Apple Intelligence function and will be released in September as usual

On August 4, Mark Gurman of Bloomberg revealed in the latest Power On newsletter that although most of Apple Intelligence's AI features have been delayed until the official version of iOS/iPadOS 18.1 in October, the iPhone 16 series of phones will not be affected and will still be launched as scheduled in September.

Apple has a precedent of delaying the release of hardware because the software is not ready. In 2011, Apple delayed the release of iPhone 4S to October because Siri and iCloud were not ready. However, it seems that Apple will not delay the release of iPhone 16 series phones because Apple Intelligence is not ready. (Source: IT Home)

Neuralink wins another victory: Second human patient successfully implanted with brain-computer interface

On August 4, Elon Musk revealed that his brain-computer interface company Neuralink has successfully implanted the second brain-computer interface chip into a human patient. This is another major progress after the first patient was implanted in January this year.

Musk shared the news on Lex Fridman's podcast. During the eight-hour conversation, Musk mentioned that the second implant is going well. Musk said: "I don't want to jump to conclusions too early, but the second implant seems to be going very well. The signal is very strong, there are a lot of electrodes, and it works very well."

The implant is part of Neuralink's PRIME study. The study aims to conduct clinical trials of implant technology for patients with quadriplegia caused by spinal cord injury or amyotrophic lateral sclerosis (ALS). The goal of the implant is to help patients control external devices, such as a computer mouse, with only their thoughts. Neuralink set the conditions for participants last year, including no history of implanted devices, no history of epilepsy, no need for MRI examinations, and no transcranial magnetic stimulation treatment.

Huolala driver refused to transport a corpse and was complained about: official response

On August 4, according to media reports, recently, a Huolala driver in Shandong found out after accepting an order that the "goods" the customer asked him to transport was actually a corpse, so he refused. The customer said, "How about I give you some more money?" After the driver refused many times, the customer even complained and threatened him.

In response, Huolala staff said that Huolala's vehicles could not meet the conditions for transporting corpses, and suggested that customers choose a suitable platform for transportation. The driver should negotiate with the customer and have no other responsibilities after canceling the order normally.

A lawyer pointed out that according to the relevant regulations on funeral management, commercial funeral equipment such as corpse transport vehicles must comply with the technical standards stipulated by the state. No unit or individual may provide body transportation services without approval. (Source: cnBeta)

3D printed "heart band-aid" is available to repair damaged tissue

On August 4, researchers from the University of Colorado Boulder and the University of Pennsylvania collaborated to develop a new 3D printing method called "CLEAR", which is expected to produce materials that can repair damaged hearts and other body parts like Band-Aids.

This new material is extremely flexible and tough, can adapt to the continuous beating of the heart and the pressure of the joints, and can be customized according to the specific conditions of the patient. The research team hopes that this technology can lead to the development of advanced biomaterials such as drug-infused heart bandages, cartilage patches and needle-free sutures.

This new method successfully creates flexible materials that are much stronger than traditional materials by simulating the complex entanglement structure of worms. These materials can not only withstand stretching and heavy pressure, but also adhere to animal tissues and organs. The researchers proved the excellent performance of the new materials through rigorous tensile and load-bearing tests, including a rather peculiar bicycle crushing test. This new method also has environmental advantages because it eliminates the energy-intensive hardening stage usually required in 3D printing.

The research team said that in the future, this 3D printed material can be used to repair heart defects, deliver tissue repair drugs directly to organs, stabilize herniated discs, and perform seamless surgical closures. At present, they have applied for a preliminary patent and plan to further study the material's response to tissues. (Source: IT Home)

Hidetaka Miyazaki: Elden Ring is the limit of our project scale

On August 4, FromSoftware President and Elden Ring Director Hidetaka Miyazaki said in an interview with The Guardian that Elden Ring has reached its limit in terms of the company's current size. He admitted that if he tried to make a game bigger than Elden Ring, he might face many challenges.

Although the world scale of many games is far larger than that of Elden Ring, its vast "Junction Land" still has an area of ​​about 79 square kilometers, which is the largest work of FromSoftware to date, and the DLC "Elden Ring: Shadows of the Golden Tree" further expands the game world.

Miyazaki said that Elden Ring has reached a new height in the scale of the company's games, and it may be difficult to make a game bigger than it in the short term. He admitted that he would be worried if he tried to surpass the scale of Elden Ring now. This seems to mean that FromSoftware currently has no plans to develop a super-large game.

Miyazaki Hidetaka hinted that the company may turn to multiple smaller projects in the future to give more talented employees the opportunity to serve as directors. (Source: IT Home)
