Here are this week's most popular stories:

1. **Google's Lumiere: New AI Model Creates Realistic Videos**

Google has introduced Lumiere, an innovative text-to-video model designed to generate lifelike videos from brief text descriptions. This advanced model produces videos with realistic motion and can utilize images and videos as additional inputs for enhanced results. Lumiere can create videos consisting of 80 frames, significantly outpacing competitors like Stability’s Stable Video Diffusion, which operates at 14 and 25 frames. The higher the frame count, the smoother the video appears. According to Google's team, Lumiere has demonstrated superior performance in various tests, including zero-shot trials, compared to rival models from Pika, Meta, and Runway.

2. **Apple Sells Over 200,000 Vision Pro Headsets in 10 Days**

In just the first 10 days since pre-orders began, Apple has reportedly sold more than 200,000 Vision Pro augmented reality headsets. This figure comes from a reliable source cited by MacRumors. Pre-orders started on January 19, with the official sales launch set for February 2. Priced at $3,500 for the entry-level model, the Vision Pro is the most expensive AR/VR headset currently available, dwarfing its closest competitor, the Meta Quest Pro, which retails around $1,000. Meta holds a commanding 55.2% market share in AR/VR headsets, with the Quest line starting at $250. Industry analysts are questioning whether consumers will embrace the Vision Pro at such a premium price point, as the 1 TB model approaches $3,900.

3. **Meta's Tips for Enhancing Prompts with Llama 2**

For optimal results when utilizing a language model, crafting the right prompt is essential. The engineering team at Meta has put together a comprehensive guide to refine prompts for Llama 2, its flagship open-source model. This guide includes an overview of the different Llama 2 variants and fundamental concepts relevant to large language models, such as tokenization and relevant APIs. Published under Llama Recipes on GitHub, the guide includes expert techniques like Self-Consistency and Retrieval Augmented Generation (RAG) to elevate user interactions with the model.
