Zuckerberg's statement marks the latest show of support for open-weight AI, which is gaining traction as ​businesses grow wary of ballooning AI costs and recent cybersecurity incidents involving models from Anthropic, OpenAI and Meta. Open-weight models are ⁠typically cheaper than leading models from the likes of OpenAI and Anthropic. Chinese startups are leading the race for open-weight models, with Moonshot's Kimi K3, Alibaba's Qwen3.8-Max and DeepSeek's V4-Flash rivalling the performance of top US systems. Growing local opposition to data centres has become a key election issue in the US and one of the biggest hurdles for Big Tech's push to build the infrastructure needed to ​power AI. President Donald Trump's administration told AI developers earlier this month that it will not put open-weight AI models ​through voluntary safety tests, according to two sources familiar with the discussions.
