Meta Platforms Inc. executives, speaking at an event Thursday, said there’s been no major drawbacks to openly sharing its AI technology, even as many peers take the opposite approach. Over the past few months, Meta has been releasing open-source versions of its large language models — the technology behind AI chatbots like ChatGPT. The idea is to keep those models free and then gain an advantage by building products and services on top of them, executives said at an event for the company’s AI research Lab FAIR. “There is really no commercial downside to also making it available to other people,” said Yann LeCun, Meta’s chief AI scientist. Meta has joined most of the world’s biggest technology companies in embracing generative AI, which can create text, images and even video based on simple prompts. But they aren’t taking the same path. Many of the top AI developers, including OpenAI and Google’s DeepMind, don’t currently open-source their large language models.
