Meta's Chief AI Scientist, Yann LeCun, emphasized that open-source models are beginning to outperform proprietary ones, specifically referencing the performance of DeepSeek. He stated that the narrative suggesting China is surpassing the U.S. in AI is misguided; instead, the correct interpretation is that open-source models are leading the way. Meta's CEO has projected that 2025 will be a pivotal year for AI, with expectations that Meta AI will become the leading assistant, serving over one billion users. Currently, Meta AI has 700 million monthly active users. The CEO also noted that LLaMA 4 is anticipated to be the state-of-the-art model, and the company aims to develop an AI engineering agent with capabilities comparable to a mid-level engineer. LeCun and the CEO both highlighted the competitive edge that open-source models, particularly LLaMA, are expected to gain over closed models in the coming year.
