Who they are

Mark Zuckerberg (1984– ) is an American entrepreneur, founder and CEO of Facebook (later Meta), who in 2013 hired Yann LeCun as chief scientist of the company’s AI research institute (FAIR), systematically investing in basic AI research. Unlike major rivals such as OpenAI and Google DeepMind that commonly take a closed-source commercialization strategy, Zuckerberg directed Meta to release its Llama series of large language models in relatively open weights, and this "open-source large model" strategy objectively greatly lowered the threshold for developers and research institutions worldwide to access frontier large-model technology and reshaped the whole industry’s path dispute over "open-source vs. closed-source." Zuckerberg has said publicly in recent years that in the long run the open-source strategy is better for ecosystem prosperity and technology democratization, a stance that has also made Meta’s business positioning in AI markedly different from its main rivals.

When the Industry Was All "Selling It Closed," Meta Chose Open Source

Against the industry background of major rivals such as OpenAI, Google, and Anthropic commonly taking a closed-source commercialization path and treating model capability as a core trade secret, Zuckerberg directed Meta to do the opposite, releasing its Llama series of large models in relatively open weights, a strategic choice that in the short term seemed to "give away" advantage to rivals and developers, yet also let Meta swiftly build a vast developer ecosystem and industry influence, this dispute over "open-source vs. closed-source" thereafter one of the core issues running through the whole development of the generative-AI industry.
