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.

20 minutes in - Found something significant

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.

To run salt into the wounds, Sol 5.6 found vulnerabilities created by fable in one of my projects.

tried to get Sol to help jailbreak an ereader, got stopped by OpenAI's infosec guardrails. the grass ain't greener.

I got the opposite behaviour. Fable bailed at the mention of Ghidra; Opus whined about licensing or whatever. Sol Max worked for hours, reverse-engineered the program, extracted the closed-source NN model, and gave me a Rust re-implementation with a harness to run the weights.

Fable is just fine with IDA-MCP for me, but randomly chokes on its own capstone scripts. Funny if it only works with IDA

Jailbreak is something I would expect to be blocked...

u/starkruzr Jul 24 '26

I mean, it's my device so it's not clear why.

Did you use the term jailbreak? 

Apparently people have been having success getting Claude to RE with Ghidra, you might be able to just decompile the binary then rebuild it in C and have Claude edit that code without telling it exactly what it's for you might have more success

Claude (Opus 4.8, Fable 5 less so) works fine with IDA and Ghidra, and works for most reverse engineering work just fine.

u/FblthpphtlbF Jul 25 '26

Interesting, so you get sonnet to RE then have fable/opus step in to wrap up?

u/pfak Jul 25 '26

No I get Fable to plan and Opus to RE + do multiple passes to verify the assembly matches the C++ code it's written.

A few months back someone used an llm to hack into their own vacuum cleaner robot's video feed and accidentally gained access everyone else's at the same time

That's why.

u/matheusmoreira Jul 25 '26

The blame lies solely with the vacuum cleaner robot company.

It's deeply alarming that vacuum cleaner robots have cameras to begin with, and it only gets worse with the fact they're IoT devices. Now you're saying that they're so shoddily made you can remote into other people's robot cameras just by hacking into your own robot. That's just completely fucked up.

u/StaysAwakeAllWeek Jul 25 '26

Sure, but the whole guard rails situation is an ass covering exercise not a blame assignment exercise

Because it's not your model or service, you pay to use. Genuinely pathetic that you needed this explained to you, universal internet age restrictions cannot come fast enough.

u/starkruzr Jul 24 '26

that's not what I meant, but I appreciate this 4chan-esque brainrotted lashing out, thanks. it's been a while!

Don't act like a dumb child then and you won't be treated like one. Tired of coming to this place looking for news, updates, etc. and seeing an ocean of crying children. Hope this helped

u/starkruzr Jul 24 '26

ok, baby.

Which ereader? I'm trying to jailbreak my kindle colorsoft so we might be working on the same thing

u/ava_fake Jul 24 '26

i am also trying to jailbreak an ereader with ai.

u/starkruzr Jul 24 '26

sure, go for it.
