Source? I haven't seen this anywhere.
In my experience, false positive rate on vulnerabilities with Claude Opus 4.6 is well below 20%.
A threat model matters and some risks are accepted. Good luck convincing an LLM of that fact
declares a 1024-byte owner ID, which is an unusually long but legal value for the owner ID.
When I'm designing protocols or writing code with variable-length elements, "what is the valid range of lengths?" is always at the front of my mind.
it uses a memory buffer that’s only 112 bytes. The denial message includes the owner ID, which can be up to 1024 bytes, bringing the total size of the message to 1056 bytes. The kernel writes 1056 bytes into a 112-byte buffer
This is something a lot of static analysers can easily find. Of course asking an LLM to "inspect all fixed-size buffers" may give you a bunch of hallucinations too, but could be a good starting point for further inspection.
And yet they didn't (either noone ran them, or they didn't find it, or they did find it but it was buried in hundreds of false positives) for 20+ years...
I find it funny that every time someone does something cool with LLMs, there's a bunch of takes like this: it was trivial, it's just not important, my dad could have done that in his sleep.
Huh, who would've expected this.
Time to update that:
"given 1 million tokens context window, all bugs are shallow"
Running LLM on 1000 functions produces 10000 reports (these numbers are accurate because I just generated them) — of course only the lottery winners who pulled the actually correct report from the bag will write an article in Evening Post
No, the problem is sorting out thousands of false positives from claude code's reports. 5 out of 1000+ reports to be valid is statistically worse than running a fuzzer on the codebase.
Just sayin'
It's definitely possible to do a basic pass for much less (I do this with autopen.dev), but it is still very expensive to exhaustively find the harder vulnerabilities.
In order to justify higher prices the SotA needs to have way higher capabilities than the competition (hence justifying the price) and at the same time the competition needs to be way below a certain threshold. Once that threshold becomes "good enough for task x", the higher price doesn't make sense anymore.
While there is some provider retention today, it will be harder to have once everyone offers kinda sorta the same capabilities. Changing an API provider might even be transparent for most users and they wouldn't care.
If you want to have an idea about token prices today you can check the median for serving open models on openrouter or similar platforms. You'll get a "napkin math" estimate for what it costs to serve a model of a certain size today. As long as models don't go oom higher than today's largest models, API pricing seems in line with a modest profit (so it shouldn't be subsidised, and it should drop with tech progress). Another benefit for open models is that once they're released, that capability remains there. The models can't get "worse".
This just isn't going to happen, we have open weights models which we can roughly calculate how much they cost to run that are on the level of Sonnet _right now_. The best open weights models used to be 2 generations behind, then they were 1 generation behind, now they're on par with the mid-tier frontier models. You can choose among many different Kimi K2.5 providers. If you believe that every single one of those is running at 50% subsidies, be my guest.
$0.001 (1/10 of a cent) or 0.001 cents (1/1000 of a cent, or $0.00001)?
Inference cost has dropped 300x in 3 years, no reason to think this won't keep happening with improvements on models, agent architecture and hardware.
Also, too many people are fixated with American models when Chinese ones deliver similar quality often at fraction of a cost.
From my tests, "personality" of an LLM, it's tendency to stick to prompts and not derail far outweights the low % digit of delta in benchmark performance.
Not to mention, different LLMs perform better at different tasks, and they are all particularly sensible to prompts and instructions.
Instead, people seem to be infatuated with vibe coding technical debt at scale.
Yea, that is what I have been saying as well...
>Instead, people seem to be infatuated with vibe coding technical debt at scale.
Don't blame them. That is what AI marketing pushes. And people are sheep to marketing..
I understand why AI companies don't want to promote it. Because they understand that the LCD/Majority of their client base won't see code review as a critical part of their business. If LLMs are marketed as best suited for code review, then they probably cannot justify the investments that they are getting...
It was Opus 4.6 (the model). You could discover this with some other coding agent harness.
The other thing that bugs me and frankly I don't have the time to try it out myself, is that they did not compare to see if the same bug would have been found with GPT 5.4 or perhaps even an open source model.
Without that, and for the reasons I posted above, while I am sure this is not the intention, the post reads like an ad for claude code.
I don't understand this critique. Carlini did use Claude Code directly. Claude Code used the Claude Opus 4.6 model, but I don't know why you'd consider it inaccurate to say Claude Code found it.
GPT 5.4 might be capable of finding it as well, but the article never made any claims about whether non-Anthropic models could find it.
If I wrote about achieving 10k QPS with a Go server, is the article misleading unless I enumerate every other technology that could have achieved the same thing?
