Mark Zuckerberg attacks ‘closed’ AI rivals as Meta returns to open models

Meta publicly pushes back against closed-model rivals after the Llama 4 launch. In an internal talk, Zuckerberg called OpenAI, Google, and Anthropic the 'big three closed players' and accused them of taxing the ecosystem through locked-down models. He confirmed Meta will stay open-source, with Llama 5 already training on a cluster of over 100,000 GPUs. The article does not disclose Llama 5's release date or parameter count.

Why it matters: Zuckerberg calls out the three closed-source rivals and discloses Llama 5's 100K GPU training scale — solid signal. But the article doesn't give Llama 5's architecture, parameter count, or timeline, so the score stops at 78 rather than higher.
