Debate over open models intensifies after Anthropic warns GLM-5.3 poses cyberattack risk
MIT Technology Review explains that Anthropic recently released a report arguing GLM-5.3 — a model published in August by Chinese firm Z.ai and available as an open-weight download — poses a major cyberattack risk. The piece frames this claim within the wider public debate between proponents of open models (who emphasize democratization, research access, and lower costs) and safety-focused actors (who warn about misuse), noting trade-offs and differing incentives among companies such as Nvidia and Anthropic.
