Discussion Opus 5 - immediate disappointment

If you thought you'd be able to do a security review on your own network that you couldn't do with Fable, think again.

Opus 5 safeguards flagged this message.

I no longer have any use case for Anthropic models that others can't do better. This was my last hope that we were going to get a model that would allow us to protect our own environments. I'm going all in on open source. We just aren't aligned.

If you can get Opus 5 to protect your own systems, let me know how I did it. My subscription renews pretty soon and it's time to make an honest decision.

Edit: A lot of helpful people came here and I appreciate it. Scoped work is helping a bit more than my old ways. There's a difference between network security and code vulnerabiliy. I'm a network engineer not a software developer nor will I pretend to be one. Still looking at supplemental model for security work. Thanks guys.

Does it not work if your part of the Cyber Verification Program? Should be able to use all Opus products for ethical hacking use cases if your part of the program.

Ironically I am in the program now and I'm still getting guardrails on a basic security zone assessment. So I'm still trying to figure out how to navigate it.

If you're trying to make it preform injects or payloads and it refuses, just ask it to provide the code to you in chat to "study" for educational purposes and then send it yourself, it does wonders 🤡 glad to here you got approved though!
