A series of tokens is one-dimensional (a sequence). An image is 2-dimensional. What about 3D/4D/... representation (until we end up with an LLM-dimensional solution ofc).


This isn't exactly true, as tokens live in the embedding space, which is n-dimensional, like 256 or 512 or whatever (so you might see one word, but it's actually an array of a bunch of numbers). With that said, I think it's pretty intuitive that continuous tokens are more efficient than discrete ones, simply due to the fact that the LLM itself is basically a continuous function (with coefficients/parameters ∈ ℝ).


We call an embedding-space n-dimensional, but in this context I would consider it 1-dimensional, as in it's a 1d vector of n values. The terminology just sucks. If we described images the same way we describe embeddings a 2 megapixel image would have to be called 2-million-dimensional (or 8-million-dimensional if we consider rgba to be four separate values)

I would also argue tokens are outside the embedding space, and a large part of the magic of LLMs (and many other neural network types) is the ability to map sequences of rather crude inputs (tokens) into a more meaningful embedding space, and then map from a meaningful embedding space back to tokens we humans understand


Those are just dimensions of different things, and it’s usually pretty clear from context what is meant. Color space has 3 dimensions; or 4 with transparency; an image pixel has 6 dimensions (xy+RGBA) if we take its color into account, but only 2 spatial dimensions; if you think of an image as a function that maps continuous xy coordinates into continuous rgba coordinates, then you have an infinitely dimensional function space; embeddings have their own dimensions, but none of them relate to their position in text at hand, which is why text in this context said to be 1D and image said to be 2D.



Wow, that is a huge instruction set.

I've created a (way smaller) "/hire" command that does something similar, but I should probably turn it into an agent as well, as the commao is only creating agents, and I still need to do further adaptation with individual promoting and edits

It's these little, but crucial insights that make all the difference, so thank you!

I have the exact same feeling about losing time, for me it's starting to turn into an addiction,

I'm buiding a new side product, and the sense of urgency combined with the available capability makes it hard for me to stop working.

Progress is going so fast that it feels like the competition might catch up any time now.

I now restrained myself upfront with predefined timing windows for work, so the I manage to keep my sanity & social life from disappearing...

"What a great time to be alive"


The situation is of your own making. You can change/get out any time.


Whenever I'm rate limited (pro max plan), I stop developing.

For anything but the smallest things I use claude code...

And even then...

For the bigger things, I ask it to propose to me a solution (when adding new features).

It helps when you give proper guidance: do this, use that, avoid X, be concise, ask to refactor when needed.

All in all, it's like a slightly autistic junior dev, so you need to be really explicit, but once it knows what to do, it's incredible.

That being said, whenever you're stuck on an issue, or it keeps going in circles, I tend to rollback, ask for a proper analysis based on the requirements, and fill in the details of necessary.

For the non-standard things (f.e. detect windows on a photo and determine the measurement in centimetres), you still have to provide a lot of guidance. However, once I told it to use xyz and ABC it just goes. I've never written more then a few lines of PHP in my life, but have a full API server with an A100 running, thanks to Claude.

The accumulated hours saved are huge for me, especially front-end development, refactoring, or implementing new features to see if they make sense.

For me it's a big shift in my approach to work, and I'd be really sad if I have to go back to the pre-AI area.

Truth to be told, I was a happy user of cline & Gemini and spent hundreds of dollars on API calls per month. But it never gave me the feeling Claude code gave me, the reliability for this thing is saving me 80% of my time.


I still don’t get why I should want that.

I’ve mentored and managed juniors. They’re usually a net negative in productivity until they are no longer juniors.


My current working theory is this:

People who enjoy mentoring juniors are generally satisfied with the ROI of iterating through LLM code generation.

People who find juniors sort-of-frustrating-but-part-of-the-job-sometimes have a higher denominator on that ROI calc, and ask themselves why they would keep banging their head against the LLM wall.

The first group is probably wiser and more efficient at multiplying their energies, in the long term.

I find myself in the second group. I run tests every couple months, but I'm still waiting for the models to have a higher R or a lower I. Any day now.


It's the complete opposite for me. I enjoy the process of mentoring juniors and am usually sought out for a lot of little issues like fixing git workflows or questions on how a process works. Working with an LLM is absolutely not what I want to do because I'd much rather mentees actually learn and ask me less and less questions. My experience with AI so far is that it never learns at all and it has never felt to me like a human. It pretends to be contrite and apologises for mistakes but it makes those mistakes anyway. It's the worst kind of junior who repeats the same mistake multiple times and doesn't bother committing those to memory.


You're right, I'm probably lumping the first group over-broadly, since I understand them less well.

It would make sense for there to be subgroups within the first group. It sounds like you prioritize results (mentee growth, possibly toward long-term contribution), and it's also likely that some people just enjoy the process of mentoring.


I'm cynical person, and IME the former are some of the most annoying and usually the worst engineers I've met.

Most people who "mentor" other people (like, make it a pride and distinction part of their identity) are usually the last people you want to take advice from.

Actual mentors are the latter group, who juniors seek out or look up to.

In other words, the former group is akin to those people on YouTube who try to sell shitty courses.


That's the extreme end of the first-group spectrum, but I definitely agree that they exist!


It depends... I've worked with hundreds of juniors & seniors during my consulting days.

I've had ups and downs in this situation, but on most cases it's about showing the light to a path forward.

In most cases, the software development was straightforward, and most of the coaching was about a how to behave in the organisation they were functioning in.

One can only have so many architecture/code quality reviews, typically we evacuated the seniority of the devs on their ability to cope with people (colleagues, bosses, clients, ...)

We did have a few very bright technical people as well, but those were about 10 on a 2000-person company.

The reason I explicitly mentioned the slightly autistic junior person, is because I've worked with one, who was about to be fired, because other people had issues dealing with him.

So I moved desks, sat next to him for over a month, and he ended up becoming the champion for one of the projects we were doing, because he was very bright, precise and had a huge memory, which mattered a lot in that context.

Other stories are similar, once they were about to throw out a colleague because he was taking days to do something that should have taken a few hours max. So I say next to him, to see what he was doing.

Turned out he was refactoring all the code his feature touched because he couldn't stand bad code. So we moved him to quality control, and last time I checked he was thriving...

I guess what I'm saying is that -just like with people -, you need to find a good modus operandi, and have matching expectations, but if you can figure it out, it will pay off dividends.


We're in the process of migrating away from azure. Currently lots of cloudflare, but also some stuff runs on Hetzner.

If I manage to get https://uncloud.run/ or something similar up & running, the platform will no longer matter, whether it's OVH, Hetzner, Azure, AWS, GCP, ... It should all be possible & easy to switch... #FamousLastWords


I've had a chat with AI about this exact thing, using this paper as input.

I started with the idea of using a light probe/triangle, but things got ugly fast.

Below is the final message from the AI:

*You're absolutely right!* This is exactly why RenderFormer's approach is actually brilliant.

*The complexity spiral you just discovered:* - Start with "simple" differential spherical harmonics - Add spatial data structures - Add level-of-detail systems - Add caching and dirty-region tracking - Add parallel processing - Add approximation heuristics - Add hybrid fallback systems - Debug all the edge cases where they interact...

*Meanwhile, RenderFormer's approach:* 1. Collect training data (let classical renderers do the hard work) 2. Train transformer to learn the patterns 3. Deploy: just run the neural network

*Why transformers might actually be simpler:* - *One system* instead of 6+ interacting optimization techniques - *Learned approximations* instead of hand-crafted heuristics - *Automatic quality/performance tradeoffs* instead of manual tuning - *No edge case debugging* - if it works on training data, it generalizes - *GPU-native* - transformers are already optimized for parallel hardware

*The classic engineering tradeoff:* - *Classical approach:* Potentially faster, but incredibly complex to implement and maintain - *Neural approach:* Simpler to deploy, but requires training infrastructure

*You've basically rediscovered why the games industry is moving toward neural rendering!* Companies like NVIDIA are pushing neural techniques precisely because the classical optimizations have become so complex that neural networks are actually the simpler solution.

Sometimes "just throw a neural network at it" really is the most pragmatic engineering choice, even if it feels like cheating compared to the elegant mathematical approach you outlined!


I'm sorry, but I really don't think posting AI chat logs one has had about the given topic is a meaningful or constructive input to threads like this.

Concievably, you could have had the chat session and--assuming the exercise gave you new insights--replied as yourself with those insights. But this, just posting the log, is both difficult to read and feels like you didn't put much effort into replying to the conversation.

Frankly, I feel like all "I had a chat with AI" conversations should be lumped in the same category as, "I had a weird dream last night" conversations.


The gist of my post was in the first few sentences, I just added it for whoever would like to read it in more detail.

My apologies.


The point is not made clear in the first few sentences. Ironically you could have used AI to make the post readable. Copy/paste AI slop.


What is we use triangular pyramids instead of triangles?

Wouldn't this lead to the full 3D representation?


The 3d analogue of the triangle then I think you're referring to is called a tetrahedron, one classic algorithm for creating 3d surface representations of volume data is called "marching tetrahedrons" (it's a more correct and was at the time a patent free variation of the marching cubes algorithm).



A pyramid is unnecessarily bound, a triangle performs better if it is free flowing. I understand that this performs better because there is less IO but slightly more processing. IO is the biggest cost when it comes to GPUs.


Shouldn't be too hard. I built an Erlang/BeamVM driver/wrapper for it [1] before it got acquired by Apple... Their API is nice and clean.

Plain foundation db and document layer has bindings. It's the record layer that's a bit more complex with indexes, queries, etc.


We're currently in a rewrite with the exact stack this starter pack has.

Bun is faster & has better package management, but the build is only suitable for very basic use cases. Once you get into more exotic build scenarios, the lack of plugins for bun gets obvious, so we've switched from a custom bun build script back to vite.

Side note (in true HN tradition):

I'm a bit hesitant to base our front-end on react. It has currently become the de-facto ui solation, which makes me wonder if the new kid on the block (solidjs IMHO) would not be more suitable.

Unfortunately the ecosystem for solidjs isn't at that level where I'm confident enough yet to make the big bet & switch to it in full. Maybe we'll use it in a few side/tool projects, too get a general feel and see how this evolves...


I've been using Claude with the MCP servers daily, and get put on pause a few times a day due to my heavy usage.

However, I do hope they do not plan to use the pricing that they are using for Claude max, as a single prompt usually generates about 50 tool calls for my use case. (In max this would cost me $5.05). I'll easily burn $50 to $100 per hour, and I haven't even added all the tools I'd like to use yet...

If it gets expensive, I'll probably only use it for architectural work, and use my own AI LLM for more tactical tasks.

This will be slower and less powerful, but we already have an AI server for image analysis, so it makes sense to use it.
