Meta's open-source AI model Llama has achieved 1 billion downloads, up from 650 million in December 2024, marking a significant milestone in the company's AI strategy. Major corporations including Spotify, AT&T, and DoorDash have integrated Llama-based models into their production systems, despite licensing restrictions. Meta plans to invest up to $80 billion in AI projects this year, with upcoming releases featuring reasoning capabilities and multimodal functionalities. However, the company faces challenges including copyright lawsuits, European privacy concerns, and increasing competition from rivals like DeepSeek's R1 model.
