That's not my experience at all. I was approved fairly fast - around an hour from submitting the form and getting a response.

However, even being in the cybersecurity programme, Fable refuses to answer prompts that it determines could be even tangentially related to cybersecurity. In fact, for a while, I was unable to use Fable with any prompt, as it recalled from memory that I was a cybersecurity professional, which triggered the refusal even for simple prompts like asking for a chili recipe.

I am guessing you are approved for the Cyber Verification Program. I also applied and got approved in an hour (on a Saturday!), but it only applies to Opus and Sonnet: https://support.claude.com/en/articles/14604842-real-time-cy.... It let me use Opus for cybersecurity work, pretty much everything except for Ransomware development. It would occasionally still trip and start saying no till I added a note about CVP in my claude.md.

No one gets to use Fable for Cybersecurity work, and Mythos is not available under CVP. Only for select few customers, and there isn't an application form?

Cyberchili. Might burn holes into corporate firewalls
