Re: Claude Opus 4.8
#342> Not only that, but we plan to release a new class of model with even higher intelligence than Opus. As part of Project Glasswing, a small number of organizations are currently using Claude Mythos Preview for cybersecurity work. Models of this capability level require stronger cyber safeguards before they can be generally released. We’re making swift progress on developing these safeguards and expect to be able to b…
Seems like they might be hinting that if you are not a billionaire or multi-billion dollar company you will just get a limited and nerfed Claude Code slash command /mythos-security-audit or something. Hope this isn’t the case and that normal average Joe’s of the world don’t get policed out of access.
> you will just get a limited and nerfed Claude Code slash command /mythos-security-audit or something.
Unless it's so expensive that we can't realistically use it for anything, I wouldn't complain about getting at least that. I would also rather have the actual model, but that's a useful application of it (and I'm probably not going to afford using it for much more).

#343Now i get why in the last days claude code limits were lasting few prompts ...

#344Anthropic also resets my usage limits (I am in the Pro plan). That's very kind of them :)
Re: Claude Opus 4.8
#345Earlier quoted context omitted.
I won't be surprised if the next gen frontier models are the last. There's orders of magnitude of low hanging juice to squeeze out of smaller models. It is almost guaranteed that a 60-90B model can outperform current SOTA in coding tasks within 2-3 years (design not certain, probably unlikely). It is far less clear that a 1.2T model will be meaningfully better enough to justify training it. As far as reasoning is con…
Took me a while to find what you were referring to by gram. Arxiv paper from 9 days ago that's not properly indexed by search engines. (G)enerative (R)ecursive re(A)soning (M)odels. They really wanted the acronym. https://arxiv.org/html/2605.19376v1
That acronym is unacceptable. It's going to impede discussion and cause confusion for a long time if it doesn't die off immediately.

#346Opus 4.7 was acting extremely stupid today. Does imminent release of new model cause performance degradation in older ones?
Opus 4.7 was being outright obstinate with me the other day it was infuriating. Had to go to a different source to get an answer.

#347It's making stupid flowcharts in the web chat interface with boxes and arrows, embedded in the response. Annoying.

#348Ugh... Invalid request The request couldn't be completed. View details API Error: 400 messages.1.content.7: `thinking` or `redacted_thinking` blocks in the latest assistant message cannot be modified. These blocks must remain as they were in the original response. I would rather not. 4.6 was fine. 4.7 got to be fine 1 week after the release. Now 4.8. No difference, same thing. But the app is broken and nothing works.…
I'm hitting this too! And I assumed it was a backwards-compatibility issue with my live conversation with Opus 4.7, but then I hit it in a fresh conversation with Opus 4.8. Vibe code release bug I guess?
Re: Claude Opus 4.8
#349On my tests[0] it does a bit worse, and it's almost 2x expensive than Opus 4.7... I was surprised to see that it failed a Data extraction test (it gets it right 2/3 times, but one time it randomly returns null for a value instead). It makes sense a bit that it fails more Trivia/Domain-specific knowledge tasks (I think models are more and more trained towards agentic use-case than general intelligence). [0]: https://a…
Wait, doesn’t the blog post say the price is the same as 4.7? > Claude Opus 4.8 is available everywhere today. Pricing for regular usage is unchanged from Opus 4.7: $5 per million input tokens and $25 per million output tokens. Pricing for fast mode is $10 per million input tokens and $50 per million output tokens. Where do you see the 2x cost?
If it spends 2x tokens to achieve the same result, that's effective 2x cost in a manner of speaking
