**[Meta Fully Shifts Focus to Closed-Source Models, New Model "Avocado" May Launch Next Spring]** BlockBeats reports that on December 10, after investing tens of billions of dollars to build one of the most expensive teams in tech history over the past few months, Meta CEO Mark Zuckerberg is now deeply involved in daily R&D and driving the company’s strategy toward monetizable AI models. According to insiders, a new model codenamed "Avocado" is expected to be released in the spring of 2026 and may be launched as a closed-source model (strictly controlled by Meta with access sold externally). This move marks a significant departure from Meta’s long-standing advocacy for open-source initiatives. Zuckerberg has devoted substantial time to a core team called TBD Lab, which, during the training of Avocado, even integrated third-party models such as Google Gemma, OpenAIgpt-oss, and Alibaba Qwen. At the same time, Meta is significantly reallocating resources, cutting investments in the metaverse and virtual reality, redirecting funds toward hardware like AI glasses, and planning to invest $600 billion in AI infrastructure in the U.S. over the next three years.
