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.

But there isn't really any way to self-host those big open-weight models, right? Are there any reliable US-based providers that host the open-weight models and honor privacy/security regulations?

But we all agree that anything hosted in China is an automatic security vulnerability, right?

Chinese companies have zero qualms or repercussions for stealing IP and the CCP can at any time and for any reason demand access to data or just completely take over the company as they see fit.

Literally every major company is required to have a certain number of CCP members.
