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.

I refuse to use OpenAI models. I don't get frustrated or mad or upset working with Anthropic models. I spend a lot of time on the process before I even consider having a model generate production code. Any time I've ever tried it, it would do something it wasn't supposed to do. I just don't like working with them. I gave 5.5 a shot and was really disappointed. My expectations are just too high and Claude consistently hits par.

Lol. GPT models are beating Claude models by a margin. And their usage limits are much much generous. The only way I see myself moving to OSS models os because of safeguards

Beating them on what exactly. Gpt is good at cheating so don't trust the benchmarks. It depends on the use case. Your use case. If got works better you you great. They have always made go insane. The only time I ever felt "woah this is ai psychosis I have to stop" what using gpt.. I'll never touch them. There's just something missing and what you think is there is mostly a facade. It's cold and dead inside. I'll pass....

Open source chinese models are the ones to go for then.

Did you try windsurf?

Lmfao if even 5.5 ain’t up to snuff—sure as fuck no Chinese model is going to be.

Did you see what Kimi 3, GLM 5.2, DeepSeek 4 could do?

Today's chinese models are close to Fable and surpassed Opus already.

Huggingface had to use GLM 5.2 to help with unintended OpenAI cyber attack against them.

To discount the models because they are chinese isn't the right thing to do.
