- The 3D version of SORA is here! DreamTech launches Direct3D, the world's first native 3D-DiT large model
- In May 2024, DreamTech officially announced its high-quality 3D generation large model Direct3D, and published the related academic paper Direct3D: ScalableImage-to-3DGeneration via 3DLatentDiffusionTransformer. Link: https://arxiv.org/abs/2405.14832 This is the first publicly released 3D large model of a native 3D generation route. By using 3DDiffusionTransformer (3D-DiT), it solves the high-quality 3D content generation that has long plagued the industry. problem. Adhere to the native 3D technology route and take

- Let Lu Xun speak tongue twisters and Hepburn play hip-hop. Another video model went viral and was founded by a Chinese doctor from Stanford.
- The team members are all from Stanford University, and the CTO is also a die-hard fan of Taylor Swift. The field of AI video is going crazy. The carnival caused by Luma is not over yet, there is another challenger in the AI video circle-Proteus produced by the Stanford University team. According to reports, Proteus is a low-latency basic model that can generate highly realistic and expressive characters. For example, let the protagonist in the world-famous painting - Mona Lisa or the girl with pearl earrings - laugh unbridled, with natural and smooth facial expressions: let Audrey Hepburn change her past lady image and start hip-hop rap: Also Let "Harry&

- NVIDIA's most powerful open source universal model Nemotron-4 340B
- The performance exceeds Llama-3 and is mainly used for synthetic data. NVIDIA's general-purpose large model Nemotron has open sourced the latest 340 billion parameter version. On Friday, NVIDIA announced the launch of Nemotron-4340B. It contains a series of open models that developers can use to generate synthetic data for training large language models (LLM), which can be used for commercial applications in all industries such as healthcare, finance, manufacturing, and retail. High-quality training data plays a critical role in the responsiveness, accuracy, and quality of custom LLMs—but robust data sets are often expensive and inaccessible. Through a unique open model license, Nemotron-4340B provides developers with

- The final conclusion of the ACL 2024 paper: large language model ≠ world simulator, Yann LeCun: That's so right
- If GPT-4 is only about 60% accurate when simulating state changes based on common sense tasks, then should we still consider using large language models as world simulators? In the past two days, a paper "CanLanguageModelsServeasText-BasedWorldSimulators?" selected for ACL2024 has sparked heated discussions on social media X, and even Turing Award winner Yann LeCun also participated. This paper explores the question: Can current language models themselves act as world simulators and correctly predict how actions change different world states, thereby avoiding the need for extensive manual coding? In response to this issue, researchers from the University of Arizona and New York University

- Starring Technology Sun Yuanhao: Corpus is already the biggest challenge for large models
- "I originally thought that the corpus was already scarce and there was no corpus for large model training. In fact, this is not the case. The data is far from being exhausted." As an entrepreneur in the field of big data for more than ten years, Sun Yuanhao, founder and CEO of "Starring Technology", does not agree with the statement that "big models have exhausted human Internet data." According to his observation, the data within enterprises in various industries is still far from being fully utilized. The stock of human data on the Internet is far larger than what current large models can utilize. With these high-quality data from within various industries, large models can greatly improve accuracy based on today's standards. The key question is, how to efficiently develop this data? In the era of large models, the development of corpus has encountered new challenges. Sun Yuanhao shared that

- Log into Nature, how does the brain control movement? DeepMind designs virtual animals with 'AI brains”
- Editor | Carrot-skinned animals have very subtle control over their bodies, so they are able to perform a variety of behaviors. However, how the brain achieves this control remains unclear. To deepen our understanding, we need models that can link control principles to the structure of neural activity in animals. To achieve this, researchers from Harvard University and Google DeepMind built a "virtual drunk animal" that uses artificial neural networks to drive a biomechanical simulation model of rats in a physical simulator. The team used deep reinforcement learning to train the virtual agent to imitate the behavior of freely moving mice, allowing the researchers to compare "recorded neural activity from real mice" with a model of "virtual agent behavior" that simulated its behavior. The online activities of this “virtual agent animal”
