Zuckerberg knocks 'closed' AI rivals as Meta swings back to open models

Meta chief executive Mark Zuckerberg is positioning the company against competitors that keep their AI models proprietary, framing Meta’s renewed emphasis on openly released models as the more trustworthy and developer-friendly path. The move signals a return to the open-weight strategy Meta pursued with its Llama family, after a period in which its direction was less clear.

The framing is as much competitive as it is philosophical: labeling rivals such as OpenAI, Google, and Anthropic as ‘closed’ lets Meta court developers, enterprises, and researchers who want to run and fine-tune models on their own infrastructure. Open weights also pressure competitors’ pricing and lock-in while seeding Meta’s models across the ecosystem.
