Cybersecurity researchers have expressed concerns about the effectiveness of Anthropic’s Fable guardrails.

Malware authors are pretty excited about guard-rails. you can add prompts to your malware to get LLM scanners to hit guard-rails and stop their runs.

Some researchers have also criticized the lack of transparency in the guardrails.

The strangest part is that it won’t just reject ML research, which I can understand, it will sabotage it silently by using a worse model without revealing it is doing so.

Anthropic has announced changes to the safeguards in response to the criticism.
