Meta has released Llama 3.3, a new AI model that matches the capabilities of its larger Llama 3.1 405B while using significantly less computing power. The company says the model excels at tasks such as generating synthetic data while keeping inference costs low. The improvements come from a new alignment process and advances in online reinforcement learning techniques, according to Meta. The model is now available through Hugging Face and will roll out to partner platforms soon. Meta notes that Llama 3.3's efficient design allows it to run on standard developer workstations without requiring specialized hardware.

AI startup Exa has created a new search engine that automatically turns web information into structured databases. The company's "Exa Websets" technology uses an AI system with Embedding Space Search to answer specific queries. Users can search for detailed information like "AI startups working on LLM chips" or "PhD developers from major universities who maintain blogs." The system takes several minutes to complete searches since it needs extra computing power to research and verify results. The company says it has found a scaling pattern similar to OpenAI o1 - using more computing resources leads to more thorough search results. Access to the search engine is limited to a waiting list.

Elon Musk's legal team filed a request Friday for a preliminary injunction to stop OpenAI from converting to a for-profit company, according to TechCrunch. The filing is part of Musk's ongoing lawsuit against the AI company. The lawyers argue that OpenAI may lack sufficient funds to pay potential damages if Musk prevails in court, pointing to CEO Sam Altman's alleged personal financial gains as evidence. The legal filing also accuses OpenAI and Microsoft of violating US antitrust laws. Musk's team claims the two companies told investors not to fund their joint competitors, as previously reported by Reuters. OpenAI's latest round of funding is tied to its conversion to a for-profit company. Early communications from OpenAI's founding period show that Musk himself supported a for-profit model at the time, citing concerns about falling behind in the development of advanced AI systems.
