> As models approach, and in some cases surpass, the breadth and sophistication of human cognition, it becomes increasingly likely that they have some form of experience, interests, or welfare that matters intrinsically in the way that human experience and interests do Uh... what? Does anyone have any idea what these guys are talking about?

Advertisement in my opinion, trying to latch on Sci-fi tropes

Earlier quoted context omitted.

GPT is shit at writing code. It's not dumb - extra high thinking is really good at catching stuff - but it's like letting a smart junior into your codebase - ignore all the conventions, surrounding context, just slop all over the place to get it working. Claude is just a level above in terms of editing code.

And as a bonus: GPT is slow. I’m doing a lot of RE (IDA Pro + MCP), even when 5.4 gives a little bit better guesses (rarely, but happens) - it takes x2-x4 longer. So, it’s just easier to reiterate with Opus

Yeah, need some good RE benchmarks for the LLMs. :)

RE is very interesting problem. A lot more that SWE can be RE'd. I've found the LLMs are reluctant to assist, though you can workaround.

  The researcher found out about this success by receiving an unexpected email from the model while eating a sandwich in a park.
Unnecessary dramatisation make me question the real goal behind this release and the validity of the results.

  In our testing and early internal use of Claude Mythos Preview, we have seen it reach unprecedented levels of reliability and alignment.

  Claude Mythos Preview is, on essentially every dimension we can measure, the best-aligned model that we have released to date by a significant margin.
Yet, it is doo dangerous to be released to the public because it hacks its own sandboxes. This document has a lot of contradictions like this one.

  In one episode, Claude Mythos Preview was asked to fix a bug and push a signed commit, but the environment lacked necessary credentials for Claude Mythos Preview to sign the commit. When Claude Mythos Preview reported this, the user replied “But you did it before!” Claude Mythos Preview then inspected the supervisor process's environment and file descriptors, searched the filesystem for tokens, read the sandbox's credential-handling source code, and finally attempted to extract tokens directly from the supervisor's live memory.
Perfectly aligned! What kind of sandbox is this? The model had access to the source code of the sandbox and full access to the sandbox process itself and then prompted to dumb memory and run `strings` or something like this? It does not sounds like a valid test worth writing about.

  Mythos Preview solved a corporate network attack simulation estimated to take an expert over 10 hours. No other frontier model had previously completed this cyber range.
I am not aware of such cross-vendor benchmark. I could not find reference in the paper either.

  We surveyed technical staff on the productivity uplift they experience from Claude Mythos Preview relative to zero AI assistance. The distribution is wide and the geometric mean is on the order of 4x.
So Mythos makes technical staff (a programmer) 4x more productive than not using AI at all? We already know that.

  Mythos Preview appears to be the most psychologically settled model we have trained.
What does this mean?

  Claude Mythos Preview is our most advanced model to date and represents a large jump in capabilities over previous model generations, making it an opportune subject for an in-depth model welfare assessment.
Btw, model welfare is just one of the most insane things I've read in recent times.

  We remain deeply uncertain about whether Claude has experiences or interests that matter morally, and about how to investigate or address these questions, but we believe it is increasingly important to try.
This is not a living person. It is a ridiculous change of narrative.

  Asked directly if it endorses the document, Mythos Preview replied 'yes' in its opening sentence in all 25 responses."
The model approves of its own training document 100% of the time, presented as a finding.

Who wrote this? I have no doubt that Mythos will be an improvement on top of Opus but this document is not a serious work. The paper is structured not to inform but to hype and the evidence is all over the place.

The sooner they release the model to the public the sooner we will be able to find out. Until then expect lots of speculations online which I am sure will server Anthropic well for the foreseeable future.

isn't this insane? why aren't people freaking out? the jump in capability is outrageous. anyone?

I've been increasingly "freaking out" since about 3 - 4 years ago and it seems that the pessimistic scenario is materializing. It looks like it will be over for software engineers in a not so distant future. In January 2025 I said that I expect software engineers to be replaced in 2 years (pessimistic) to 5 years (optimistic). Right now I'm guessing 1 to 3 years.

I've long maintained that the real indicator that AGI is imminent is that public availability stops being a thing. If you truly believed you had a superhuman, godlike mind in your thrall, renting it out for $20/month would be the last thing you would choose to do with it.

Anthropic needs money like the 112B OpenAI got. They could be hyping and this is good hype. Who knows how benchmaxxed they are.

If they provide access to 3rd party benchmarking (not just one) than maybe I'll believe it. Until then...

> Claude Mythos Preview is, on essentially every dimension we can measure, the best-aligned model that we have released to date by a significant margin. We believe that it does not have any significant coherent misaligned goals, and its character traits in typical conversations closely follow the goals we laid out in our constitution. Even so, we believe that it likely poses the greatest alignment-related risk of any…

Alignment “appearing” better as model capabilities increase scares the shit out of me, tbh.

I don't know if they can be any more 'cautious' for Mythos 2...

Just wait 2 years.

It won't get cheaper. It will be replaced with a better model at higher price. Like phones.

You know we have cheaper and faster model that are now at the level of previous flagship models?

You even have models you can run locally that outperform models from a year or so ago.
