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.
