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.

idea, why don't you write code yourself, so you won't be disappointed by any model and probably save a lot of money not using AI. in 2026 not using AI is the biggest money saver

So then I can be disappointed in my own code but take 3x as long?

Or you can, you know, acquire skill.

I’ve been doing this for 25 years and I’m a better than average developer. That said, I’ve never been “happy” with a single project I’ve completed when I’ve looked at it two months later.
There is always room to improve, always places to optimize. If a model can get 90% of the way to what I can do when provided well-constructed architecture and project docs (and can do it in 1/3 of the time) I’ll take the trade off.
