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?

> 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."

> Not particularly “dangerous” I'm not sure that follows. As noted, curl was already analyzed to death with every tool available; most software isn't at that level.

I don't think I understand what you mean, the "not particularly dangerous" comment was in relation to the vulnerability that was found right ? Surely they would know what constitutes a lower severity level.

The "not particularly dangerous" is a headline for a section talking about Mythos, not the vulnerability.

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 in tsz are really really difficult and I've seen Opus bailing again and again. So annoying to waste time and tokens to finally get "this is too involved" or "this requires a multi-week sprint to fix".

Ah okay, that makes a bit more sense. I read it wrong. Then the comment is absolutely fair.

It's a shame he seems to reject the idea of actually diving in and using these tools interactively:

> It’s not that I would have a lot of time to explore lots of different prompts and doing deep dive adventures anyway.

His expertise I think would elevate the results quite a bit. Although if he never uses LLMs, which it reads like he doesn't, I guess it might backfire just as well. Prompting style (still?) does matter after all, certainly in my experience anyways.

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

> The source code consists of 660,000 words, which is 12% more words than the entire English edition of the novel War and Piece. Typo, or is there a spoof I should go read?

War and Peace is about 590,000 words. Tiny compared to the full Harry Potter collection (about 1 million words over the 7 books), but long for a single book.

The new Opus feels like a step backwards. More expensive, thinks more, and it does not get the job done.

They're referring to the typo in the title, "Piece" vs "Peace".

I also thought they were contending the word count before noticing. Even remarked how I find this a weird metric, given that code is not prose [0], but then I deleted that once I picked up on what's going on.

[0] comparing the output of `wc -w` with the word counts of books I'm reasonably sure will be super off

edit: ran a calc, substituting out symbols (but not underscores), digits, and comments yields a 390K word count compared to the 660K cited. not excluding the comments yields 600K, so more than a third of all words in the sources are comments.
