Vitalik Buterin voiced support for Kimi 3.1 restricting access to advanced cyberattack tools. His reason was not that the restriction could hold them back for long: he acknowledged that other labs would still develop cyberattack tools of a similar level.

According to him, the filter is meant to buy time, not to block them permanently. This is an assessment explicitly attributed to Vitalik himself, not a verified industry-wide conclusion.

The material does not specify the filter’s technical standards or scope, nor does it say who released Kimi 3.1. There is currently no verifiable data linking the expression of support to the filter’s actual effectiveness.
