Opus 5.5 is a good model, but I've tried to understand the extreme hype about it on social media about Opus' ability to do 2d work, as we got with Astra doing 3d work. In both releases, the models required extensive access to third party apis to generate assets for it, and a lot of the models work was essentially coordinating everything.

There's so many "x generated this in one shot, this is agi" stuff that gives you the impression that you can vibe operate modern models the same way you operated last year's models. There's so much more to it than that. It requires you to put a faith in the leap in the capability of models, one that would've surely been a waste of time in previous models.

Not sure where i'm going with this other than I think most can relate that it's exhausting keeping up with. I cant imagine what it'd be like parenting a kid that went from toddler to puberty in the span of a year and planning for them to go to college the next year. This industry is moving so fast that it's becoming fact that it's the user that's "holding it wrong" every six months.

Opus 5.5 does NOT need anything other than some javascript/typescript libraries to make very detailed 2d and 3d visualizations. I've spent a week worth of tokens just feeling out what it can do.

The step function change on Opus 5.5 for visual work shocked me.. and I haven't been surprised like this in a long time with LLMs.

This "how to prompt" shit changes like every 3 months. Remember when earlier this year it was critical to tell Claude to keep going because it would just give up. It's amazing this is really considered a product - imagine having to relearn how to drive your car every 3 months.

All this overhyped crap will explode and most of us will be poor but hey whatever. Some billionaires will be better off. That should make us all content

Not sure how you missed that but models are fundamentally changing in features, scope, intelligence, pricing, communication style. Of course it changes every 3 months. Of course there is no product that lasts more than 3 months. We're in a race right now. It won't stop changing for a while.

Yeah. It is not so much like a "coding assistant", but more like a temp agency sending you different autists every other month.

> Frontend design defaults

> Asked for frontend work without design direction, Claude Opus 5.5 falls back on a few default styles, and a general instruction such as "avoid a generic AI look" mostly swaps one default for another. It responds well to instructions that name specific patterns to avoid, as in the following example. Work iteratively: check which styles the first result used instead, and extend the list if needed.

I hardly ever read tips for prompting etc. because things change too quickly, the writeups are kindof big. Glad I read this one, because I often did exactly what they assume users would do. I write "don't make it look like generic ai slop" and that seemed to work nicely. Now I know why there was still a chance of seeing similar styles across apps. I reckon doing some manual work in terms of scouting dribbble/behance for nice layouts will yield better results.

First thing it did when I tried it, was roaming through files in directories way outside of the project. I tried to get it to explain why it did it multiple times, but I never got anything resembling an explanation.

What we know after the openai incidents is that RSI involves models having access to all of our rollouts via tool calls. What's considered crappy training one year is another year's kompromat!
