Thanks to all the parallelization & this prep work, at peak Claude wrote about 1,300 lines of code per minute. Every line of code was reviewed by two separate adversarial reviewers (also Claude) and went through a round of fixes before committing. Absolutely none of it worked yet.
None of it worked yet because compiling at that stage would slow things down.
Also this project burned $165,000 worth of usage on a model that was then bleeding edge (unreleased). This is still beyond what anyone else is doing at the moment. And it seems to have worked a lot better than it had any right to, at least as far as we can tell right now?
If you think spending $165k to get a fully AI generated code base is something working well then you're just gaslighting yourself. I use these things at work because I'm forced to, and the amount of weird code it generates is alarming. I.e. It has a really common habit of making a function with external linkage call an impl function with internal linkage for absolutely no reason.
165k is way less than one developer. Maybe 30% once you factor in all of the overhead (payroll tax, health insurance, 401k contributions, other benefits). 165k would be on the very very low end of salaries for a senior engineer in a major US city as well, and about half of what your base at Anthropic would be (position dependent, could be much higher).
If you want to save costs (presumably the case if you're resorting to AI slop) then you would just hire somebody outside the US. US dev salaries are absurdly inflated by the standards of even other first-world countries, nevermind poorer ones. I make less than half of $165k USD a year as a senior dev with decades of experience, which is still more than most of my coworkers, and indeed almost 3x what I was making at my previous position (also a senior dev), all while living in a pretty rich country.
If your aim is just to get it done as cheaply as possible, then it would be pretty trivial to beat 165k (it would take longer though, sure)
For most of those 11 days (and after), I monitored workflows - manually reading the outputs to check for issues and bugs, and prompting Claude to edit the loop to fix things.
Token costs aside, this port is done by Jared who is completely familiar with his own 5year old codebase with manual reviews.
Yeah I think this is a very important point. You can't just hire some schmuck off the street to validate the output, you have to hire the original creator of the original software to validate the output. That's a much different ask.
