Vitalik Buterin Backs AI Model That Deliberately Cut Its Hacking Skills

Ethereum co-founder Vitalik Buterin has backed Moonshot AI’s decision to strip top-end hacking skills from its new Kimi K3.1 Pro model. In his view, limiting what AI can do beats limiting who may use it. However, the safeguard comes at a measurable cost. Moonshot says the filtered model solved 81% of tasks on its internal exploit benchmark, while an unfiltered version solved 90.5%. Why Vitalik Buterin Prefers AI Limits Over User Checks Buterin shared his stance, arguing that discriminating against use cases is far less harmful than discriminating against users. Moonshot, a Beijing-based AI startup, plans to release the model’s open weights by November 4. Anyone can then download it and run it on their own hardware.
