Anthropic is no longer a good model company in my mind, they are optimizing for an IPO and padding themselves on the back for being the next Aristotle. They're so far up their behind they don't realize how s**y their products are, and their research team hasn't done anything ground breaking in probably over a year other than release "scary" reports.
The truth for me at least is that these models became "good enough" around Opus 4.6. I feel like further capability improvements, "step changes" like we saw with agentic coding, aren't necessarily going to come from the model. I think the next crown goes to whoever can figure out the right scaffolding so that these models can be inserted into your organization.
Maybe I'm wrong and Opus 5 is a real unlock?
My thoughts: fable is the bigger model. Opus is distilled from it but since it is smaller it doesn’t need the online classifiers. Though benchmarks show Opus to be near Fable level, I think it’s nowhere near Mythos (fable without safeguards).
Quick read is that this is more capable and cheaper than 5.6sol. Same price for input tokens and $5 cheaper per mil output tokens.
Finally! But I don't see it in claude code yet..
Can I ask it about DNA without it accusing me of bioterrorism?
...nothing to say,a toothpaste.
so almost fable 5 with 50% cheaper cost? sign me up
Can someone help me understand something? I thought Fable was such a miraculous leap forward in capability. But now it seems Opus is basically on par with it, and in some cases (computer use) far exceeds it.
In the wake of OpenAI’s model hacking Huggingface it’s interesting how the first quarter is entirely about how good Opus 5 is at hacking and finding vulnerabilities in software.
Yay just in time for neurips lol
> . Opus 4.8 served as fallback on safety-classifier refusals for Opus 5 and Fable 5.
ffs just keep it man.
here we go
Am I misreading anything or are comparisons to Fable (and/or Mythos although AFAICT it was only a crackdown on Fable) always going to be a bit missing the mark now due to what the Trump admin did?
Just another proof that the supposed edge of Fable and Mythos were just that: myths and fables.

Why should I be amazed at something that promises to destroy my life?
I genuinely don't understand why people who have to work for their living are amazed at this. It will have a vast negative impact on your life unless you already live off of your wealth.

> Claude Opus 5 is not more capable overall than our most capable general-access model, Claude Fable 5
Ok then so what's the point?
this claude fable & opus 5 should be cheaper and can compete in pricing with chatgpt latest models
I think it's the first time Anthropic release a model without any meaningful disruptions while doing it
It looks great, and those coding benchmarks are impressive... now if only it didn't come out just days after I let my Claude subscription expire :')
These cybersecurity safeguards are really annoying. There are ethical reasons to reverse-engineer and binary-patch software; for example Rewind got acquired by facebook and, as a gift to all their customers, implemented a killswitch in their software to ensure it will eventually stop functioning. I kept using a version without the killswitch, but the macOS 27 update killed it, and I needed binary patching to fix it. I should be allowed to repair software I purchased (I did purchase it like a month before they sold out), but unfortunately this overlaps significantly with cybersecurity.
