The Wall Street Journal reported on June 10 that backlash has emerged among AI developers and users regarding the limitations of Claude Payable 5, which was unveiled the previous day.
Claude Payable 5 is a model adjusted for general users from the "Mythos" series, which Anthropic deemed too risky for broad release.
When users engage with sensitive topics such as biological weapons or cybersecurity, a warning message appears, and the conversation is switched to a lower-performing model from the previous generation. Restrictions that degrade the quality of responses are also applied to advanced AI development questions.
Some of these restrictions are not visible to users. Anthropic explained that it has implemented "invisible restrictions" on AI development responses for reasons related to national security and service terms. This has made it difficult for some researchers to evaluate the model's performance externally.
There have also been reports of general scientific inquiries being blocked. Some users claimed that questions related to mathematics, biology, and chemistry were denied. One user shared a screen showing that Claude Payable 5 refused to answer a basic cell biology question about mitochondria.
Immunologist Derya Unutmaz, a researcher at the Jackson Laboratory, stated, "Because the existing conversation history included biological topics, I was unable to input even the word 'cancer' or a greeting."
Anthropic has apologized for the invisible restrictions, acknowledging that "hidden safety measures make it more challenging to assess and circumvent the model." The company admitted to making a poor compromise and failing to strike a balance. It added that it would ensure users can see these restrictions in the future.
Regarding the restrictions in the life sciences field, the company explained that a conservative approach was necessary initially to prevent misuse. Furthermore, it stated that it would reduce unnecessary blocks and provide models like Claude without safety measures to biology and life science researchers.
