Comment by George Balston

Open-weight models introduce new and unique risks – they provide near-frontier capabilities which could be used for criminal purposes, are widely available to anyone who intends harm, and are easier to misuse. [...] Major frontier AI companies such as OpenAI, Anthropic and Google do not release the weights of their frontier models. This means they alone can patch the model, add or tighten safeguards, and as a last resort remove the model from circulation entirely. An open-weight model, on the other hand, has no such restrictions – the developer publishes the weights and thereafter has no meaningful ability to recall, patch or supervise any copies.
