Anthropic has issued a report arguing that Z.ai's GLM-5.3 model presents significant cyberattack risks due to its open availability, intensifying the debate between open-weight and closed AI models. The article contrasts this safety concern with the economic and geopolitical benefits of open models, such as preventing market concentration and enabling local deployment for sensitive data. While closed models offer built-in safety filters, open models allow for deeper research, customization, and cost savings, though they lack access revocation mechanisms. Industry leaders like Nvidia advocate for open models to drive hardware sales, whereas Anthropic warns of the dangers of unfiltered access.

The ruling forces xAI to face scrutiny over air quality impacts at its Colossus data center, setting a precedent for how large-scale compute facilities are regulated under existing environmental laws.

OpenAI is scaling back its ambitions as investor appetite for massive AI infrastructure bets cools. The company has lowered its fundraising target from $30 billion to $20 billion, with only $11 billion secured so far against a valuation that has dropped from $1.4 trillion. This retreat signals a growing wariness among Wall Street investors regarding the capital intensity of the AI race, forcing even the most dominant players to adjust their financial expectations.
