Elon Musk announced the start of training for the world's most powerful AI training cluster at xAI's new supercomputer facility in Memphis, Tennessee. The Memphis Supercluster features 100,000 liquid-cooled H100 GPUs on a single RDMA fabric, giving xAI a significant advantage in training AI by December this year. The project is a collaboration between xAI, X, and Nvidia.

Meta released Llama 3.1 405B, a GPT-4-class large language model that can be downloaded for free and run on a single server node. The model rivals top AI models in general knowledge, steerability, math, tool use, and multilingual translation. Meta CEO Mark Zuckerberg calls it the first frontier-level open source AI model. The model is not suitable for desktop PCs, requiring beefy hardware.

Researchers at the University of Hull, led by Dr. Kevin Pimbblet, have developed a technique to detect AI-generated deepfake images by analyzing reflections in human eyes. The method, presented at the Royal Astronomical Society's National Astronomy Meeting, uses tools adapted from astronomy to scrutinize the consistency of light reflections in eyeballs. The technique is based on the principle that a pair of eyes being illuminated by the same set of light sources should have consistent reflections.

OpenAI has launched GPT-4o mini, a smaller version of its GPT-4o AI language model, which will replace GPT-3.5 Turbo in ChatGPT. The new model will be available for free users and those with ChatGPT Plus or Team subscriptions starting today, and will come to ChatGPT Enterprise next week. GPT-4o mini will be multimodal, interpreting images and text, and will use DALL-E 3 to generate images. It will also employ a technique called instruction hierarchy, which prioritizes certain instructions over others.

Former OpenAI researcher Andrej Karpathy has announced the formation of Eureka Labs, a new AI learning platform that aims to create an 'AI native' educational experience. The platform's first offering will focus on teaching students how to build their own large language model (LLM). Karpathy's approach pairs expert-designed course materials with an AI-powered teaching assistant based on an LLM, providing personalized guidance at scale.

Microsoft CTO Kevin Scott believes that large language model scaling laws will continue to drive AI progress, despite skepticism. He played a key role in a $13 billion technology-sharing deal between Microsoft and OpenAI. Scott stated that the progress is not at diminishing marginal returns on scale up and that there is an exponential pattern, but it takes time to build supercomputers and train models.

OpenAI unveiled a five-tier system to gauge its advancement toward developing artificial general intelligence (AGI), which is a hypothetical concept that means an AI system that can perform novel tasks like a human without specialized training. The company shared this new classification system with employees during an all-hands meeting, aiming to provide a clear framework for understanding AI advancement. OpenAI has previously stated that AGI is its primary goal.
