It looks like this doesn't work for users without accounts? It works when I'm logged in, but not logged out. I went ahead and reported it to the team. Thanks for letting us know!

No integration test for guest (non-logged in) users? Hahaha who am I kidding. No integration tests for anybody!

But but but but I thought AI would do this magically for all of us, no?

No more need for pesky humans, no?

I find it quite funny how this blog post has a big "Ask ChatGPT" box at the bottom. So you might think you could ask a question about the contents of the blog post, so you type the text "summarise this blog post". And it opens a new chat window with the link to the blog post followed by "summarise this blog post". Only to be told "I can't access external URLs directly, but if you can paste the relevant text or descri…

Like building on quicksand for dependencies. I guess though the argument is that the foundation gets stronger over time

What dependancy could possibly be tied to a non deterministic ai model? Just include the latest one at your price point.

There's a whole universe of tasks that aren't "fix a Github issue" or even related to coding in the slightest. A large number of those tasks doesn't necessarily get better with model updates. In many cases, the performance is similar but with different behavior so you have to rewrite prompts to get the same. In some cases the performance is just worse. Model updates usually only really guarantee to be better at coding, and maybe image understanding.

If you're trying to use LLMs in an enterprise context, you would understand. Switching models sometimes requires tweaking prompts. That can be a complete mess, when there are dozens or hundreds of prompts you have to test.

This sounds made up. Much like “prompt engineering” Let’s hear an actual example

Like, bro, do you think 5.x is a drop in replacement for 4.1? No it obviously wasn’t, since it had reasoning effort and verbosity and no more temperature setting, etc.

There’s no way you can switch model versions without testing and tweaking prompts, even the outputs usually look different. You pin it on a very specific version like gpt-5.2-20250308 in prod.

wat

maybe gp's use of the word "lots" is unwarranted https://artificialanalysis.ai indicates that sonnect 4.6 beats opus 4.6 on GDPval-AA, Terminal-Bench Hard, AA Long context Reasoning, IFBench. see: https://artificialanalysis.ai/?models=claude-sonnet-4-6%2Ccl...

I was basing it off my recollection of this:

basically 9/13 are very close

We have an OCR job running with a lot of domain specific knowledge. After testing different models we have clear results that some prompts are more effective with some models, and also some general observations (eg, some prompts performed badly across all models). Sample size was 1000 jobs per prompt/model. We run them once per month to detect regression as well.

While I believe that performance varies with respect to prompt, I have a seriously hard time believing that using the same prompt that was effective with the previous model would perform worse with the next generation of the same model from that lab and the same prompt.

You shouldn't have a hard time believing it. There are thousands of different domains out there. You find it hard to believe that any of them would perform worse in your scenario?

Labs are still really optimizing for maybe 10 of those domains. At most 25 if we're being incredibly generous.

And for many domains, "worse" can hardly be benched. Think about creative writing. Think about a Burmese cooking recipe generator.

SDET here. A year ago when AI came into play SDET/QA roles started disappearing. People were like oh ya anyone can write tests. Then with the recent fiascos about outages and what not, I am seeing the SDE roles are disappearing and SDET roles are going back up?! Apparently AI is good at writing applications but you still need someone to make sure it is doing the right things.

It’s not really good at writing the software either — it’s a moderate to decent productivity booster in an uneven, difficult-to-predict assortment of tasks. Companies are just starting to exit the “we’re still trying to figure this out” grace period. Expect more of that as soon as these chatbot companies have to start charging enough to pull in more money than they spend. I foresee some purpose-built models that are pretty lean being much more useful in long run. It’s neat that the bot which can one-shot a simple CRUD website for you can also crank out Scrubs-based erotic fan fiction novellas by the dozen but I don’t foresee that being a sustainable business model. Having good purpose-built tools is, in my opinion, better than some unwieldy tool that can do a whole bunch of shit I don’t need it to.

Interestingly, the first real productive use of AI that I found was writing the unit tests and integration tests for my applications. It was much better at thinking about corner cases that I was.

I am very curious about this: > Theme park simulation game made with GPT‑5.4 from a single lightly specified prompt, using Playwright Interactive for browser playtesting and image generation for the isometric asset set. Is "Playwright Interactive" a skill that takes screenshots in a tight loop with code changes, or is there more to it?

The skill source is here: https://github.com/openai/skills/blob/main/skills/.curated/p...

$skill-installer playwright-interactive in Codex! the model writes normal JS playwright code in a Node REPL
