Anthropic has closed access to Fable for all users

Anthropic has closed access to Fable for all users. This is the result of a requirement from the US government to close access to Fable for all non-citizens, including Anthropic employees. Since Anthropic does not have a system to verify citizenship, access was closed for everyone. The reason was a partial jailbreak that allowed the use of Fable to search for vulnerabilities. The vulnerabilities found are quite simple and can be found by other publicly available models. Whether Anthropic can fend off this and how serious the government's intentions are depends on the fate of the market.
