I like how they highlighted Opus 5 as the best for “Agentic Coding” even though the number is slightly lower than Fable. Close enough for marketing, I guess!

Earlier quoted context omitted.

Funny that a company selling an AI software developer can't use it to fix their infra. Fixing those issues still requires humans.

How many companies at the size of Anthropic can serve the amount of traffic and manage the amount of compute they have?

It doesn't matter. Front end code should not misbehave if servers can't keep up. At worst it should fail gracefully.

> Opus 5’s safeguards match those of Claude Fable 5’s, with one change: it now permits source-code vulnerability discovery at all access levels. This means that the model can support defensive cybersecurity work while still blocking vulnerability discovery in compiled binaries, which is more commonly used offensively. Okay so it’s worse than Opus 4.8 for my purposes I guess?

Presumably it drops back to 4.8 in those cases so it's not really worse

yes. At the bottom of the release post it says that they are releasing two new features, one of which is customizing fallback behavior instead of blocking for restricted models

I mean that certainly makes it best-in-class

HN users are world champions are trivializing difficult things with snarky comments

Best can describe multiple things. Almost as good for half the cost is something I'm very comfortable describing that way.

Best marketing

At half the price and less likely to auto-downgrade, it sounds like a reasonable claim.

Half the price of Fable 5 and useable with 100% of your subscription means roughly 4x the usage using Opus 5, presuming similar token use for solving problems.

Not that they should get credit for giving you only 50% of your plan worth of Fable usage but still.

Isn’t it just hilarious that a model that seemed so superior to Fable but didn't get doomsay marketing from Anthropic got released without any issues? In theory, this was supposed to be AGI level according to Anthropic, yet here we are, just a normal Friday.
