When I see how much the latest models are capable of it makes me feel depressed. As well as potentially ruining my career in the next few years, its turning all the minutiae and specifics of writing clean code, that I've worked hard to learn over the past years, into irrelivent details. All the specifics I thought were so important are just implementation details of the prompt. Maybe I've got a fairly backwards view…

Trust me, these “vibe coding” tools don’t speed up productivity much in the real world. At the end of the day these systems need to be maintained by humans and humans are the ones held accountable when stuff breaks. That means humans need to understand how the systems (code, infrastructure, etc) work. You can automate the code, even some decisionmaking about how the program should be organized, but you can’t automate…

I'm scrolling through lots of comments here over many of them being entirely dependent on chatbots to vibe code and even some here are unable to write a function by hand anymore, which is concerning.

Perhaps your comment is the only one so far that is talking sense of the true side effect of over-reliance on these vibe coding tools and the reality is the cost of maintainance.

I haven't shouted into the void for a while. Today is as good a day as any other to do so. I feel extremely disempowered that these coding sessions are effectively black box, and non-reproducible. It feels like I am coding with nothing but hopes and dreams, and the connection between my will and the patterns of energy is so tenuous I almost don't feel like touching a computer again. A lack of determinism comes from m…

If you allow your codebase to grow unfamiliar, even unrecognisable to you, that's on you, not the AI. Chasing some illusion of control via LLM output reproducibility won't fix the systemic problem of you integrating code that you do not understand.

Does 4.5 still answer everything with "You're absolutely right!" or is it now able to communicate like a real programmer?

It still says "Perfect!" about its own work far too often.

Why did you have access to a preview?

Could you please stop breaking the site guidelines? You've been doing it repeatedly, we've asked you to stop several times, and you haven't stopped yet.

We end up banning that sort of account, so if you would please review https://news.ycombinator.com/newsguidelines.html and stick to the rules from now on, that'd be good.

I had access to a preview over the weekend, I published some notes here: https://simonwillison.net/2025/Sep/29/claude-sonnet-4-5/ It's very good - I think probably a tiny bit better than GPT-5-Codex, based on vibes more than a comprehensive comparison (there are plenty of benchmarks out there that attempt to be more methodical than vibes). It particularly shines when you try it on https://claude.ai/ using its brand n…

That minutiae was always borderline irrelevant, the skill was always making somebody money, possibly with software. The reality is that more software will be pushed than before, and more of it will need to be overseen by a professional.

> minutiae was always borderline irrelevant, the skill was always making somebody money That's extremely reductive, and a prime example of why everything is enshittified today.

Do you actually disagree with the "minutiae was always borderline irrelevant" part or that it comes along with "making somebody money"? I pretty strongly agree with the original quote including the "possibly with software" part.

Minutiae such as tabs vs spaces and other formatting changes are pretty clearly "borderline irrelevant" and code formatters have largely solved programmers arguing about them. Exactly how to best factor your code into functions and classes is also a commonly argued but "borderline irrelevant." Arguments about "clean code" are a good example of this.

Broadly, the skills I see that LLMs make useless to have honed are the the minutiae that were already "borderline irrelevant." Knowing how to make your code performant, knowing how to make good apis that can be stable long term, in general having good taste for architecture is still very useful. In fact it is more useful now.

Anecdotal evidence. I have a fairly large web application with ~200k LoC. Gave the same prompt to Sonnet 4.5 (Claude Code) and GPT-5-Codex (Codex CLI). "implement a fuzzy search for conversations and reports either when selecting "Go to Conversation" or "Go to Report" and typing the title or when the user types in the title in the main input field, and none of the standard elements match, a search starts with a 2s de…

Curious if Opus would have done it differently than GPT-5-Codex.

Also, trying GPT-5-Codex

Same. I haven't written any code by hand in some time. Oh well. I guess I'm just doing it wrong.

Have you built anything public that folks can try out? Not doubting but it helps to contextualize things

https://app.grantpuma.com/

It's a startup for finding grants. We have california state, federal, non-profit and california city/county grants. My landing page absolutely sucks but if you sign up / upload some papers or make some search cards you'll like the experience.

I'm very excited to try out the new Qwen XL that came out recently for visual design. I could really use some better communication to users of the capabilities of the platform.

I think clean code is more important than ever. LLMs can work better with good code (no surprise), and they are trained on so much shit code they produce garbage in terms of clean code. They also don't have a good taste or deeper architectural understanding if big codebasis where it's even more important.

What you learned over the years, you can just scale up with agents.

I’m not sure this is entirely what you’re driving at, but the example I always think of in my head is “I want an AI agent that will scan through my 20 to 30,000 photos, remove all the duplicates, then organize them all in some coherent fashion.” that’s the kind of service I need right now, and it feels like something AI should be able t…

azure vision / "cognitive services" can do this for literally a few bucks am i even on hacker news? how do people not know there are optimized models for specific use cases? not everything (nor should it) has to run through an LLM https://azure.microsoft.com/en-us/pricing/details/cognitive-...
