I need to try Claude - haven't gotten to it. I use AI for different things, though, including proofreading posts on political topics. I have run into situations where ChatGPT just freezes and refuses. Example: discussing the recent rape case involving a 12-year-old in Austria. I assume its guardrails detect "sex + kid" and give a hard "no" regardless of the actual context or content. That is unacceptable. That's like…

It's a service, not a tool. If you want a tool, run some local LLM.

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…

I even added a disclaimer "anecdotal evidence". Believe me, I am not the biggest fan of Sam. I just happen to like the best tools available, have used most of the large models and always choose the one that works best - for me.

Why did you have access to a preview?

Simonw is a cheerful and straightforward AI journalist who likes to show and not just tell. He has done a good job aggregating and documenting the progress of LLM tools and models. As I understand it, OpenAI and Anthropic have both wisely decided to make sure he has up to date info because they know he'll write about it. Thanks for all your work, Simon! You're my favorite journalist in this space and I really appreci…

I like Simon, but he's not a journalist. A journalist would not have gone to OpenAI to glaze the GPT-5 release with Theo. I don't say this to discount Simon -- I appreciate his writing and analysis but a journalist, he isn't.

I just ran this through a simple change I’ve asked Sonnet 4 and Opus 4.1, and it fails too. It’s a simple substitution request where I provide a Lint error that suggests the correct change. All the models fail. I could ask someone with no development experience to do this change and they could. I worry everyone is chasing benchmarks to the detriment of general performance. Or the next token weight for the incorrect c…

> I worry everyone is chasing benchmarks to the detriment of general performance. 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…

The reality of that specific ask is it would not be difficult to build, but I believe it would be extremely difficult to build and offer at a price that users would pay for. So you're unlikely to find a commercial offering that does that using a (V)LM.

There's exactly ONE factual claim about AI in this entire subthread, and it is word-for-word "AI has been a huge help for my work". Now you may read that as .. checks notes "star trek post scarcity singularity", but forgive me, I didn't.

> Practically speaking, we’ve observed it maintaining focus for more than 30 hours on complex, multi-step tasks. Really curious about this since people keep bringing it up on Twitter. They mention it pretty much off-handedly in their press release and doesn't show up at all in their system card. It's only through an article on The Verge that we get more context. Apparently they told it to build a Slack clone and left…

“30 hours of unattended work” is totally vague and it doesn’t mean anything on its own. It - at the very least - highly depends on the amount of tokens you were able to process. Just to illustrate, say you are running on a slow machine that outputs 1 token per hour. At that speed you would produce approximately one sentence.

Has their comment has been edited? A few words later it says it resulted in 11,000 LoC.

Please y'all, when you list supportive or critical complaints based on your actual work, include some specifics of the task and prompt. Like actual prompt, actual bugs, actual feature, etc. I've had great success with both ChatGPT and Claude for years, am around 3x sustained output increase in my professional work, and kicking off and finishing new side projects / features that I used to simply not ever finish. BUT t…

I had Claude Code build a fairly complex swiftui app (5+ screens), using Firebase AI Logic and other packages. First prompt it got pretty much foundation for the entire thing set up, then over the next day got it working exactly like I wanted. The thing that took the longest was getting through app review. I was impressed how well it knew SwiftUI and Swift composable architecture.

I’m always fascinated by the fine-tuning of LLM personalities. Might we finally get less of the reflexive “You’re absolutely right” with this one? Maybe we’re entering the Emo Claude era. Per the system card: In 250k real conversations, Claude Sonnet 4.5 expressed happiness about half as often as Claude 4, though distress remained steady.

No change to “absolutely right”. I did get “You’re right” once though.

I'm not trying to be offensive here, feel the need to indicate that. But that prompt leads me to believe that you're going to get rather 'random' results due to leaving SO much room for interpretation. Also, in my experience, punctuation is important - particularly for pacing and grouping of logical 'parts' of a task and your prompt reads like a run on sentence. Making a lot of assumptions here - but I bet if I were…

> I bet if I were in your shoes and looking to write a prompt to start a task of a similar type that my prompt would have been 5 to 20x the length of yours Why would you need such extensive prompting just to get the model to not re-implement authentication logic, for example? It already has access to all of the existing code, shouldn't it just take advantage of what's already there? A 20x longer prompt doesn't sound…

Well, I don't have the context myself about what's happening in this example, though I don't see anything about auth myself.

And I left that window at 5-20x because, again, no real context. But unless I was already in the middle of a task and I was giving direction that there was already context for - my prompt is generally almost never _this_ short. (referring to the prompt in the top level comment)

> A 20x longer prompt doesn't sound like a satisfying solution to whatever issue is happening here.

It wouldn't be, given the additional context given by the author in a sibling comment to yours. But if you had specific expectations on the resulting code/functionality that 20x longer prompt is likely to save you time and energy in the back and forth adjustments you might have to make otherwise.
