Open-weight models also come with publicly accessible core components for easy customization, unlike closed models that companies keep fully under their control.\n\nPOLICY RETHINK NEEDED TO PROPEL OPEN-WEIGHT\n\nZuckerberg said in a statement that the U.S. needed to rethink policies if domestic firms were to lead in open-weight models.\n\nChinese startups are leading the race for open-weight models, with Moonshot's Kimi K3, alongside Alibaba's Qwen3.8-Max and DeepSeek's V4-Flash, delivering performance that rivals top systems by U.S. AI labs. By contrast, the leading models of U.S. developers OpenAI, Anthropic and Alphabet's Google are closed source.\n\n\"Foreign labs currently hold several advantages here since American labs have to comply with many additional restrictions on training data,\" Zuckerberg said, referring to open-source models.\n\n\"US policy must reduce this additional friction if we want American open source models to lead over time,\" Zuckerberg said, adding that restricting access to foreign open-source models was not an effective solution.\n\nU.S. 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.", "url": "https://wpnews.pro/news/meta-launches-new-ai-model-as-zuckerberg-champions-open-weight-push", "canonical_source": "https://ca.finance.yahoo.com/news/meta-launches-ai-model-zuckerberg-100121407.html", "published_at": "2026-08-10 10:01:21+00:00", "updated_at": "2026-08-10 10:38:06.568894+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-policy", "ai-products", "large-language-models"], "entities": ["Meta", "Mark Zuckerberg", "Muse Glimmer", "Hugging Face", "Moonshot", "Alibaba", "DeepSeek", "OpenAI"], "alternates": {"html": "https://wpnews.pro/news/meta-launches-new-ai-model-as-zuckerberg-champions-open-weight-push", "markdown": "https://wpnews.pro/news/meta-launches-new-ai-model-as-zuckerberg-champions-open-weight-push.md", "text": "https://wpnews.pro/news/meta-launches-new-ai-model-as-zuckerberg-champions-open-weight-push.txt", "jsonld": "https://wpnews.pro/news/meta-launches-new-ai-model-as-zuckerberg-champions-open-weight-push.jsonld"}}
