My phrasing wasn't clear but you aren't telling it to only look at one specific file but to focus its review on one file. Updated my original comment.

The technique Anthropic uses was demonstrated by Nicholas Carlini in a talk he gave 2 weeks ago and it's very simple, when asking LLMs to review code, ask them to focus its review on one file in a single session. Here is the video with the timestamp (watch through to ~5:30, they show two different ways of prompting claude).

IMO the big "innovation" being shown by Mythos is the effectiveness with prompting LLMs to look for security vulnerabilities by focusing on specific files one at a time and automating this prompting with a simple script.

Prompting Mythos to focus on a single file per session is why I suspect it cost Anthropic $20k to find some of the bugs in these codebases. I know this same technique is effective with Opus 4.6 and GPT 5.4 because I've been using it on my own code. If you just ask the agent to review your pr with a low effort prompt they are not exhaustive, they will not actually read each changed file and look at how it interacts with the system as a whole. If the entire session is to review the changes for a single file, the llm will do much more work reviewing it.

Edit: I changed my phrasing, it's not about restricting its entire context to one file but focusing it on one file but still allowing it to look at how other files interact with it.

> if the AI can just write really good code in C that doesn't exhibit any of the issues that rust protects you from?

"if"

If it could you wouldn't need to use Rust. It can't, qed.

You can prevent unsafe from being used in a repo with linter rules.

This is where you can opt out. It's absurd that they are automatically opting users into this.

Also if anything it should disappear when scrolling down and appear when scrolling up.

Does it only work with that specific version of firecracker and only with vms with 1 vcpu?

More than the sub ms startup time the 258kb of ram per VM is huge.

People don't want to buy 2x8gb because there are limited slots on a motherboard and they want to upgrade when they need the extra ram.

You can go on OVH and get a dedicated server with 384 threads and a Turin cpu for $1147 a month. You have to pay $1147 for installation and the default has low ram and network speeds but even after upgrading those it's going to be 1/5 of what it would cost on public clouds.

The AI could also research which stores are reputable.

> People still /are/ scared to buy things from Amazon for things that go on or in their body.

Sure, there are also people scared of flying in airplanes, those must be a dud too going by your logic.

If I hand my shopping list to AI, why wouldn't I tell it to price match everything? People will start doing this sooner than you think. I still remember when people were scared to buy things on the internet, this will be faster.

In other words, switching costs go to 0, margins collapse. Middle men and people with products that aren't differentiated get hit hardest.

A human can't search 10 apps for the best rates / lowest fees but an agent can.

Thinking ahead 100 years from now, companies like doordash and uber eats don't exist and are instead protocols agents use to bid for items their user asks for and price discovery happens in real time.

Do you use youtube intending to be drawn into watching things you never intended to watch? I don't want a feed but the people operating these sites do not care that they are destroying people's time. Go to twitter, click on "following". Next time you sign in, somehow it's on "For you" (the algorithmic feed).

Thankfully on Youtube I can completely disable recommendations on the site and I use it purely as a source of information, not as a dopamine addiction funnel.
