tracyhenry··on Dots: Always-on agents
I always think the best company to own an alway-on agent should be Apple, who owns the platform and is more privacy-focused. I hope they catch up and eventually eliminate others.
tracyhenry··on Jev in 25 Lines of Python
This, like the hype of Jev on Twitter, totally ignores accuracy and generality across domains.

In my experience even structured LLM output performs poorly on classifier tasks. LLMs are trained to talk and think longer. If you don't give LLM enough space to reason it would become very dumb.

I'm not saying that Jev is way better, but that people way overindexed cost and speed.

tracyhenry··on OUI-1: world's first model for Generative UI
When the blog title is "world's first model for Generative UI", you are supposed to show something that GPT/Claude couldn't do. Instead it's all benchmark.

I don't know what media you are talking about. It's all slop worse than current slop.

tracyhenry··on OUI-1: world's first model for Generative UI
design is the hard problem. i don't know what hard problem this is trying to solve here
tracyhenry··on OUI-1: world's first model for Generative UI
Generative UI is unsolved because current models do not have taste and end up generating the same kind of slop.

I'm amazed that this blog doesn't even have a single screenshot/photo of the kind of UI they can generate.

Focusing on benchmarks in this domain feels very wrong.

tracyhenry··on Ask HN: Initial Thoughts on GPT-6 Astra?
No one on HN seems to care about its crazy ability in 3D modeling?

3D might have just been solved like coding

tracyhenry··on Memorizing session transcripts isn't useful
The only times I found the memory feature useful are in "projects" I created myself.

In a project my questions are usually revolved around the same topic. Having context carried across threads actually make a lot of sense.

In the general mode where I'm expecting models to be *stateless*, having memory is very annoying.

tracyhenry··on Ask HN: Are you still using a Vision Pro?
At the end of the day, it only makes sense if watching a movie on AVP gives you immense joy, which is the case for me.

If you can charge your phone, you can charge your vision pro. The battery itself can last any movie with no problem.

tracyhenry··on Ask HN: Are you still using a Vision Pro?
Not regularly, but I do watch movies on it once in a while (in those beautiful environments), especially when I'm on a flight.

WWDC also just rolled out some quite exciting features to RealityKit: https://developer.apple.com/videos/play/wwdc2026/279/ as well as visionOS itself (https://developer.apple.com/videos/play/wwdc2026/287/)

It makes me wonder if Apple is really giving it up as news have claimed.

tracyhenry··on How OpenAI delivers low-latency voice AI at scale
After all these, I still feel their voice AI interrupts quite a lot, especially when I pause just for 0.5 sec. Interestingly, when I tell it to interrupt less, it seems to be better.
tracyhenry··on Vercel’s pricing page
off topic but I just wonder if this page is AI-designed. It looks quite good to my eyes. I feel like prior to coding agents this would instead be a blog post with some charts.
tracyhenry··on Ask HN: What Are You Working On? (April 2026)
I'm building Eima (https://eima.app) which combines your Todo List and Calendar, allowing you to schedule your todos by simply dragging them onto the calendar.

Similar apps have existed before (like Amie), but they were nearly all VC-backed and had pretty much all pivoted to AI (e.g. being an AI note taker). Their approaches to a Todo-focused calendar has been largely unsatisfying due to the focus on Enterprise users and whatever is trendy.

Eima, in contrast, focuses on personal use and does one thing very well: scheduling your todos. In particular, I spent a lot of time making sure multi-occurrence todos work smoothly (e.g. todos that need multiple attempts or simply recurring todos). These were not addressed by prior tools at all and had been my biggest motivation to build Eima.

Would love some test users! If you end up wanting to give Eima a try please use the code EARLYEIMA to get it for free.

tracyhenry··on Claude Code Unpacked : A visual guide
idk why you bring this up. this is irrelevant to whether CC actually works at big corps
tracyhenry··on Claude Code Unpacked : A visual guide
> they break at large enterprise repos.

I don't know where you get this. you should ask folks at Meta. They are probably the biggest and happiest users of CC

tracyhenry··on GitHub Copilot Coding Agent
I'm honestly surprised by so much hate. IMHO it's more important to look at 1) the progress we've made + what this can potentially do in 5 years and 2) how much it's already helping people write code than dismissing it based on its current state.
tracyhenry··on Launch HN: Confident AI (YC W25) – Open-source evaluation framework for LLM apps
This looks great. I would love to know more what makes Confident AI/DeepEval special compared to tons of other LLM Eval tools out there.
tracyhenry··on Show HN: App to discover job listings directly from company websites
+1

I think one rule around Show HN is that you allow people to see content without signing up, let alone paying for it. So this is a violation of that rule.

Edit: actually search is not behind the paywall (although that's not very obvious)

tracyhenry··on With AI, the future of augmented reality is in your ears
couldn't take this article seriously considering it doesn't mention Meta's Rayban smart glasses, which largely does what they want already: a pair of glasses without visuals but with AI in your ears
tracyhenry··on Orion, our first true augmented reality glasses
This is a pretty common view for Vision Pro users. Hand tracking is great for these. Can't imagine having to use a controller.

Ofc Vision Pro users are extreme minorities so you are not wrong. But I highly encourage you to try out Vision Pro if you haven't.

tracyhenry··on Launch HN: Haystack (YC S24) – Visualize and edit code on an infinite canvas
This has been a great idea for decades. I want Haystack to be successful just like many other attempts. The early execution seems promising. And I suspect there will be many challenges (e.g. when it's hard to figure out caller/callee,, inconsistent UX preferences across developers, etc). Kudos for taking this on!

Btw I've always thought that this is even more powerful when the screen estate is more infinite than a 2D screen (like in a VR headset).

tracyhenry··on Most of Europe is glowing pink under the aurora
Thank you, this looks amazing
tracyhenry··on Most of Europe is glowing pink under the aurora
please post a photo!
tracyhenry··on Meta AI
Llama 3 is the open source model while this is a product offering competing w/ ChatGPT, Claude and Gemini. Not a dupe imo.
tracyhenry··on Show HN: Mazelit - My wife and I released our first game
thank you so much
tracyhenry··on Show HN: Mazelit - My wife and I released our first game
looking forward to it!
tracyhenry··on Show HN: Mazelit - My wife and I released our first game
+1 really well made. I wonder if there's a framework for making these kind of websites?
tracyhenry··on Rabbit: LLM-First Mobile Phone
I'm talking about AR glasses, not Vision Pro.
tracyhenry··on Rabbit: LLM-First Mobile Phone
My hot take:

ALL AI wearable companies should return their money to investors, and wait for the AR glasses by Apple.

AR glasses are the ultimate form factor. And as much as I hate monopoly, Apple has the right app/dev ecosystem, and will make Siri work.

tracyhenry··on The New York Times is suing OpenAI and Microsoft for copyright infringement
I don't quite get it. If listing your link is considered as theft, HN is then a thief of content too. If you don't want your content stolen, just tell Google to not index your website?

I guess it's more constructive to propose alternatives than just bashing the status quo. What's your creator compensation model for a search engine? I believe whatever being proposed is trading off something significant for being more ethic.

tracyhenry··on The New York Times is suing OpenAI and Microsoft for copyright infringement
> the first being at the birth of modern search engines.

Why do you say that? Search engines would at least direct the viewer to the source. NYT gets 35%+ of its traffic from Google: https://www.similarweb.com/website/nytimes.com/#traffic-sour...
