I'd go out and say the marketing is not subtle. The hype and fanboys/girls are so in line with the marketing that any level of skepticism is seen a an act of defection, but if you look at the words, hyperbole and volume that is used, there is nothing subtle about it. It's almost Trump-esque - "this model will change everything forever; we are doomed; we are saved; we will all be fired; we will all be rich", etc

I seem to be totally outside the hype bubble, but I have to suspect there is a lot of imagineering and wild extrapolations in the elss technical hype bubbles. I am curious but no enough to go looking.

I don't know about Mythos but in recent weeks I've noticed Opus is constantly failing to fix things in tsz[0] vs GPT 5.5 can easily churn out fixes that are solid and pass tests. I've stopped paying for Claude for now and all my money is going to OpenAI at the moment. Either Opus is massively nerfed or GPT 5.5 is really head and shoulder higher in terms of very difficult tasks. The last percent of conformance tests i…

Having never used Claude and only Codex, does Claude actually say “this is too involved” as a response to a prompt?

Yes it does. Usually after hours of working and not getting results

> No, based on cURL's history, it really seems like they would love to have found a really novel bug. You just confirmed that you didn't read the article. "Eventually, I was instead offered that someone else, who has access to the model, could run a scan and analysis on curl for me using Mythos and send me a report."

I'm not sure how that proves I didn't read the article ?

Perhaps he was dictating. Does it say anything else? Just 'Aaaarggghhhh'?

Doubt it considering that Daniel Stenberg is Swedish. English dictation when you speak English as a second language with an accent is quite annoying.

Voice input works really well for people speaking English with a Swedish accent. I think the accent of most educated Swedes is mostly a case of prosody. For sure there are some sounds we say slightly differently than native English speakers. We often have some trouble with /s/ and /z/, but I don't know, "war and peace", I think that's easily understood.

Source: voice typing this with Swedish vocal chords, and only had to correct "different lives" to "differently", and add /[^\w\s]/.

I routinely used to compile C programs on other compilers to find defects that one or another didn't find. Compiling on Windows vs Linux. You could summarize / minimize it down to compiling it with warning as errors etc but you'd be missing the point.

The point wasn't actual cross-platform portability even though that was a nice side effect. It was to flush out all the weird edge cases.

Edges like security flaws. Buffer overflows are usually platform specific. There are plenty of other ways to find these issues but simply recompiling for a different platform surfaces all sorts of issues.

They might be biased by the fact that curl is significantly more secure than the average software

> An amazingly successful marketing stunt for sure.

This. Well done by Antropic.

It even reached the CISO of my small semi-government org in the Netherlands, who slightly panicked at the announced 'tsunami' of vulnerabilities that was coming with Mythos.

Got us some more money and priority with the board, though.

Never waste a good marketing scare.

Putting on my tinfoil-hat: Sooo, the guy who runs the test and delivers the report could just have removed the more interesting bugs and delivered those to any three letter agency?

The test was run by an unnamed third party, so cURL's history has no relevance to their benevolence.

There is always marketing involved and people should be able to put marketing into perspective. Also curl in this regard is a open source project, relativly small but critical, well known and used everywhere. Besides image libraries, tools like curl or sudo, su, passwd, etc. would also be my first try. Mythos is still not known at all what it can do. What does it mean from cost and benchmark pov to have a 10 Trillion…

> Nonetheless, the fact that LLMs got significant better in finding this, better than humans, started to happen half a year ago?

*rolls eyes* regular static analyzers also have been "better than humans" for decades, being better than a human at a specific mechanical task really doesn't mean much. The interesting new thing is the type of potential "fuzzy bugs" described in the article that LLMs are able to identify (a comment not matching the code it describes, uncommon usage of a 3rd party library, mismatch of code and a protocol it implements, or often just generally weird looking code somebody should have a closer look at... this closes a gap in the traditional debugging toolboxes, but shouldn't replace them)
