I think the point is that gcc was made over decades by hundreds of compiler experts. Claude code is a relatively new product that didn't exist a few years ago, and it can output complex systems like a compiler faster than almost anyone in the world. This is a quantum leap forward in LLM-generated code, which is a field only a few years old at this point.
You'd think it's stupid to spend 20k to write a broken compiler, but consider how much you'd need to pay humans to make a broken compiler in the same amount of time.

MASSIVE increase in power.
Shattered every benchmark.
It's exactly like working with contractor mills in India minus the time difference. You pay more for the privilege of watching Ranjeet fail to understand basic instructions immediately instead of at 4AM the next day.
The problem is code maintenance, not code generation
This is still downplaying the accomplishment. The compiler is a compiler. Sure it doesn't work without an assembler. It also doesn't work without a computer, or RAM, but it's a compiler.
1:39 20 cents…?
Trying to picture this as a failure for AI is truly stupid. $20.000 for building a working C compiler from scratch (even a crappy one) in two weeks is something outstanding, impossible to do just months ago. The software industry will be absolutely transformed this year. And fragile minds in negation of reality like yours will be the most affected. Look at the bigger picture and embrace AI agents now, for your own good.
Amazing video
The agents didn't even write the code from scratch / isolated. They made the agents write small chunks of the compiler that they then tested with GCC filling in all the other missing code, this is how the agents were looped until they succeeded. So they did who knows how many little puzzle pieces one by one each having to match GCC otherwise the puzzle piece wouldn't fit. It's a huge embarrassment. Also it's unfortunate that more people didn't read the blog post thoroughly enough to spot this huge insane detail.
Thank you for not being a fanboy!
Really refreshing.
I'm using ChatGPT to create formulas for dynamically genereated tables in Google Sheets. It has dramatically increased my productivity, but occasionally it produces a formula with errors that it is unable to resolve. I was a programmer, so I know how to shift into debug mode to give assistance. In most cases, I only need to identify the problematic area of the code, but even in some of those cases ChatGPT is sure that it has the right answer and remains stuck despite my promptings. It lacks the ability to dig itself out of a hole and reminds me of the old wisom about owning a four-wheel-drive vehicle–it does not guarantee that you will not get stuck, but it does guarantee that you will only be stuck in a place that requires a second four-wheel-drive vehicle for rescue.
Yeah that's it.
AI can't create "new" code and solve new problems, it can just reoutput what has already been done by a human.
And imagine maintaining this crap code with nobody (including the AI) knows what it’s doing
Love those kinda news..
For the past year or so I've been less afraid of an actual "AI takeover" than I've been afraid of halfwit AI's being let loose on our infrastricture and potentially casuing irreversible damage though their own incompetence.
100,000 lines compiler? Isn't that too much?
Making fun of claude while you cant do 100/20 🤡🤡
A loss for clankers is a victory for mankind.
0:41 What does “kind of” works mean? It can’t be good.
As real as “China will invade Taiwan in 6 to 12 months” 😂
Trained on 40 years of stolen GCC compiler code and yet it still fails to even copy and paste that well. Unfortunate.
5 dollars per line of code 20k/100k
???
You can tell how skerd the coders are by how much copium they have to regurgitate when their competition gets a little bit closer to threatening their cheeto dusted fingers out of a job. It's probably fine when code you write puts filing clerks out of a job because it's "disruptive," but not so funny when your code is starting to look like you may be the next casualty.
LLMs can't replace any niche field. You will never find enough content to train it
1:11 So a fancy autocomplete couldn't autocomplete the open source compiler. Who could have guessed
Something something monkeys with typewriters Shakespeare
20 cents per line brother
I want to thank you for helping me put all this news into perspective. As a software engineer, I have my future livelihood depending on the trajectory of these tools and I sometimes feel like I'm loosing my mind when I hear colleagues or LinkedIn gurus boast about all these seemingly impressive feats that I simply can't seem to replicate myself, using these agents. I keep fearing that some technique or tool will catch me offguard and make me irrelevant due to me not understanding how to direct it properly.
Six months always seems so far away for tech companies.
These videos are nice, but I am not a fan of that clearly copied Fireship style …
1:35 your math is just as shit as the ai
Hmm, 20 000 for developing a C compiler is not bad, I don't think humans could do it more cheaply and obviously it cannot be better than compilers that have several years of collective development behind.
However it's a fair point the fact that it's an over-documented task.
Compilers are deterministic and Gen AI is probabilistic. No one wants to deal with a probabilistic compiler
you do no know how to use it.
That’s because it’s a D compiler. AI is thinking an entire alphabet ahead of you cringey AI skeptics. AI out here playing 3.141592 dimensional chess with your grandma.
It's free on github, 2k stars, every AI-hater wanting to find flaws, yet it only has 30+ issues. And those issues are mostly youtube comments 2.0. The cope is insane.
20 thousand dollars for dead code.. lmao 🤣
1:31 love how you blurred so little the name is obvious
it seems like they really just used gcc for all the important stuff
I don’t know if it is worst ever – the one I wrote in college was pretty bad.
Seems like they are in the "one more lane bro" phase. "One more agent bro"
1:37 bro let gpt do the math… it's actually 5 lines per dollar
Have you ever tried it yourself?
I love using tools that are known for being unreliable for tasks that are famously very error-sensitive.
In germany we call such a technology a still birth. A solution for a non-existent problem and or a failure by conzept! 😂
