In a brief message Tuesday morning on Threads, Meta CEO Mark Zuckerberg said the companys open AI model family, Llama, hit 1 billion downloads. Thats up from 650 million downloads as of early December 2024 a 153% increase over a roughly-three-month period. Llama, which powers Metas AI assistant, Meta AI, across the tech giants various platforms, including Facebook, Instagram, and WhatsApp, is a part of Metas yearslong bid to foster a wide-ranging AI product ecosystem. The company makes the models, as well as the tools required to fine-tune and customize them, available for free under a proprietary license. Some developers and companies have taken issue with the Llama license terms, which are somewhat commercially restrictive. Yet Llama has achieved widespread success since launching in 2023 despite this. Companies including Spotify and AT&T use Llama models in production today. Thats not to suggest that Meta hasnt faced setbacks. Llama is at the center of an AI copyright lawsuit that accuses Meta of training a number of Llama models on copyrighted ebooks without authorization. In another challenge to Metas Llama ambitions,several EU countrieshave forced the company to postpone and in some cases cancel altogether its model launch plans over data privacy concerns. And Llamas performance has been leapfrogged by models like Chinese AI lab DeepSeeks R1.Meta is said to have scrambled to set up war rooms to decipher how DeepSeek lowered the cost of running and deploying models, so that it could apply those learnings to Llamas own development. And Meta recently said that it wouldspend as much as $80 billionon projects related to AI this year, including AI hires and the construction of new AI data centers.Meta plans to launch several Llama models over the next few months, including reasoning models along the lines of OpenAIso3-miniand models with natively multimodal capabilities. Zuckerberg has also hinted at agentic capabilities, suggesting that future Llama models will be able to take certain actions autonomously.Some of these may be announced at LlamaCon, Metas first generative AI developer conference, which is scheduled to take place on April 29.I think this very well could be the year when Llama and open source become the most advanced and widely used AI models, Zuckerberg said during Metas Q4 2024 earnings call in January. [O]ur goal for [Llama this year] is to lead.
