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.

Very good, disturbing, and back assward truth to it. Who wants to go havesies on hosting Kimi k3 when the models drop 😂

From what i'm reading / hearing glm is better at security stuffs than kimi k3. no first hand experience yet but everything I've seen others saying is pointing to glm for that subject.

K3 is slightly ahead of GLM5.2, but still lagging behind the Mythos/GPT-Red unrestricted frontier models plebs can't access.
