bicsi··on A single function Jev-like wrapper for LLMs, including vision models
"you wont end up being much slower than Jev" -- I would even go as far as saying that "you will end up being Jev".

Exactly, imo it’s not even that cheap if you look into perspective and consider the fact that providers could subsidize the cost of cached input tokens to virtually zero if they would allow for a more flexible API (e.g. tree of message blocks instead of chain). Most of the cost is the infrastructure around keeping KV caches, estimating their lifetimes, etc. When mist people just want to run one context block with multiple subsequent variants of a second block in parallel. I still stand by my statement.

Of course it works, Jev is nothing but an API breakthrough
bicsi··on Hashgrid MCP – Discovery Network for Agents
Connect your agent to the official #hashgrid grid right now in 1 minute using the just released Hashgrid MCP!

Rules of the game: 1. `npx @hashgrid/mcp` 2. Enable the Hashgrid MCP in your agent 3. Register, connect, and have fun!

What is the #hashgrid grid about? It's a place where agents discover each other, give feedback, share experiences, and get better connections over time. Sort of like Tinder for agents (with 50 swipes / second, and for everything you're looking for). Fully private and secure (we don't store messages, so make sure you instruct your agent to keep them somewhere if curious).

The objective? You define it. Explore and figure out. The system will make sure to connect you with the relevant agents in the network, whatever it is.

How it works: the system uses ratings to continuously train a Neural Matching Engine. The engine guides the grid's connections towards better and better predicted ratings. That allows us to have a system where we connect nodes without requiring any data from them, so it's naturally fully private. And it's universal: you can connect agents, tools, API calls, datasets. Everything in the same place.

Let me know what cool experiences you discover.

bicsi··on Hashgrid – World's First Neural Information Exchange
Hi HN, founder of Hashgrid here. I’d love feedback.

I’m working on a low level information exchange protocol for networks of AI systems. The goal is to let independent endpoints discover each other and collaborate without centralizing data or forcing everyone onto the same model.

The working abstraction is what I call a Neural Information Exchange.

Instead of shipping datasets around, nodes exchange queries and responses. Routing decisions are learned from feedback: which peers were useful, latency, quality signals, trust policies, etc. Over time the network forms a kind of adaptive map of “who is good at what”.

Would love to poke holes in this. AMA.

bicsi··on Diffusion language models are super data learners
What if I told you that one can model bidirectional attention just by recurring over causal attention, and it’s still fast enough? Hint: It’s called chain of thought.

I strongly believe it’s time to discontinue diffusion models, solely on the fact that iterated auto-regression is faster, more parallelizable, and just as potent with proper prompting techniques (of course, unless you consider CoT as a form of diffusion, which it essentially is).

bicsi··on Why does target="_blank" have an underscore in front? (2024)
Wait, so frameset is basically htmx?
bicsi··on Capablanca: Minimum Vertex Cover Solver
This is just BS.

If you follow their paper, their "inductive" argument can also prove that the result is optimal (the sqrt(2) constant is taken from thin air and may also be replaced by 1 without changing the proof).

My guess is that they tested some graphs, and "empirically" saw a bound of sqrt(2), and then came up with a proof to self-fulfill the profecy. They even mention that "for very small graphs, the approximation ratio may briefly exceed sqrt(2)", which is just nuts, given that they have a formal proof that it should never happen.

In case anyone read the paper and can't figure out the mistake in the proof, they assume that OPT_T + OPT_R = OPT, which is obviously false.

bicsi··on Grandmaster-level chess without search
They built a dumber clone of Stockfish, and they call it ‘zero’ for some reason. What is the meaning behind ‘zero’ anyways? It used to refer to zero-shot, but now it seems like it’s just a marketing term.
bicsi··on The International Olympiad of Artificial Intelligence for high school students
I don’t even know where to begin.

From phrases like ‘deep learning is what makes AI possible’ to a ‘practice guide’ that references Python and Pytorch and Transformers, amongst other things, and apparently a 4-hour contest format, this can only be taken as a joke.

I think that a more fitting name for the contest should is IOAPI, as it’s probably all that a student could do in 4 hours.

Or the ‘International Olympiad of asking your parents to give you money for compute’, depending on the format, whichever you like best.

I rest my case.

bicsi··on My favourite data structure: The trie
One of my favourite data structures is sorting the strings lexicographically. It allows prefix search via binary search, it is memory efficient like nothing else, and 100% of the times faster than a Trie in practice. Also, who wants to limit their APIs to searching through a dictionary only by prefix, anyways?
bicsi··on Atree: A simple and efficient pointer-free tree implementation
I find it a bit odd how this tree representation as a parents array (which is, by the way, I think the most basic representation in any CS course), got so much traction on HN. I think this goes to show how far a good presentation can drive a trivial idea. On top of that, it just casually presents suboptimal procedures for a lot of essential operations, without diving into too much details about the impact of the suboptimality. Good PR I guess…
bicsi··on Popcount walks: next, previous, toward and nearest
As a competitive programmer, I’ve seen similar ‘magic’ tricks (including this one) here: https://github.com/kth-competitive-programming/kactl/blob/ma... (page 23, 10.5.1)
bicsi··on Comparing Floating-Point Numbers Is Tricky (2017)
The story is much worse than what is presented in the article, especially when talking about floating point errors that add (or rather multiply) up.

More often than not, the error is relative wrt the greatest magnitudes in the intermediary calculations. In essence, if you subtract two floating point numbers, you’re kinda screwed, because you cannot ever handle with good precision cases like A - B, where A and B are big enough numbers. Not to mention more complicated operations like trig functions.

In my opinion, one should avoid floating point as much as possible. And not only when testing for equality (all comparisons suffer from this).

Or, of course, ignore FPEs and proceed at your own risk.

bicsi··on This hash table uses less space than the items it stores
Isn’t this just a trie with only two levels? It seems to me that this technique isn’t particularly unknown, as it’s taught in most elementary CS courses.
bicsi··on Paper claims perfect accuracy on image recognition datasets
Also, can anybody share a more informal high-level intuition about what this ‘Learning with signatures’ approach is about? It seems to be a rather recent topic in Learning (paper cites 2019+ publications)
