keeeba··on Sonnet 5.5
Thank you for the pelicans sir, how do you think they compare to other models in Sonnet’s pricing/capability range?
keeeba··on Claude Opus 5.5
Opus 5.1 came out about a month ago, what gives?
keeeba··on Navier-Stokes – Tristan Buckmaster [pdf]
The elves left a long time ago, it’s difficult to see much virtue in what remains.
keeeba··on Understanding is the new bottleneck
Also interested
keeeba··on Dostoyevsky isn't difficult
This is not an attempt at affected nonchalance, but I’ve simply never come across the idea that Dostoevsky is particularly difficult to read.

A somewhat gifted teenager will race through it, as will an average adult.

keeeba··on Microsoft and OpenAI end their exclusive and revenue-sharing deal
Not hired Suleyman? Build his own research lab?

Satya made moves early on with OpenAI that should be studied in business classes for all the right reasons.

He also made moves later on that will be studied for all the wrong reasons.

keeeba··on Statement on the comments from Secretary of War Pete Hegseth
The gap between Anthropic and the other guys keeps growing
keeeba··on Statement from Dario Amodei on our discussions with the Department of War
Big respect

Total humiliation for Hegseth, sure there will be a backlash

keeeba··on Learning from context is harder than we thought
To somewhat state the obvious - the problem isn’t the amount of data, it’s the algorithms.

We need to discover the set of learning algorithms nature has, and determine whether they’re implementable in silicon

keeeba··on The Codex App
Is everything OpenAI do/release now a response to something Anthropic have recently released?

I remember the days when it was worth reading about their latest research/release. Halcyon days indeed.

keeeba··on Project Genie: Experimenting with infinite, interactive worlds
“ This is one of my fundamental beliefs about the nature of consciousness. We are never able to interact with the physical world directly, we first perceive it and then interpret those perceptions. More often than not, our interpretation ignores and modifies those perceptions, so we really are just living in a world created by our own mental chatter.”

This is an orthodox position in modern philosophy, dating back to at least Locke, strengthened by Kant and Schopenhauer. It’s held up to scrutiny for the past ~400 years.

But really it’s there in Plato too, so 2300+ years. And maybe further back

keeeba··on Show HN: Use Claude Code to Query 600 GB Indexes over Hacker News, ArXiv, etc.
I don’t have the experiments to prove this, but from my experience it’s highly variable between embedding models.

Larger, more capable embedding models are better able to separate the different uses of a given word in the embedding space, smaller models are not.

keeeba··on GPT-5.2
Doesn’t seem like this will be SOTA in things that really matter, hoping enough people jump to it that Opus has more lenient usage limits for a while
keeeba··on Python is not a great language for data science
As a fairly extensive user of both Python and R, I net out similarly.

If I want to wrangle, explore, or visualise data I’ll always reach for R.

If I want to build ML/DL models or work with LLM’s I will usually reach for Python.

Often in the same document - nowadays this is very easy with Quarto.

keeeba··on Claude Opus 4.5
Oh boy, if the benchmarks are this good and Opus feels like it usually does then this is insane.

I’ve always found Opus significantly better than the benchmarks suggested.

LFG

keeeba··on Venn Diagram for 7 Sets
Please don’t actually use these 5,6,7-way Venn diagrams for anything practical, they’re virtually useless and communicate nothing.
keeeba··on Generalized K-Means Clustering
I agree it is a profound question. My thesis is fairly boring.

For any given clustering task of interest, there is no single value of K.

Clustering & unsupervised machine learning is as much about creating meaning and structure as it is about discovering or revealing it.

Take the case of biological taxonomy, what K will best segment the animal kingdom?

There is no true value of K. If your answer is for a child, maybe it’ 7 corresponding to what we’re taught in school - mammals, birds, reptiles, amphibians, fish, and invertebrates.

If your answer is for a zoologist, obviously this won’t do.

Every clustering task of interest is like this. And I say of interest because clustering things like digits in the classic MNIST dataset is better posed as a classification problem - the categories are defined analytically.

keeeba··on Claude Skills
“Skills are a simple concept with a correspondingly simple format.”

From the Anthropic Engineering blog.

I think Skills will be useful in helping regular AI users and non-technical people fall into better patterns.

Many power users of AI were already doing the things it encourages.

keeeba··on Improved Gemini 2.5 Flash and Flash-Lite
It came from nowhere to 1T tokens per week, seems… suspect.
keeeba··on Gemma 3 270M re-implemented in pure PyTorch for local tinkering
What use-cases do you see for the 270M’s embeddings, and should we be sticking to token embeddings or can we meaningfully pool for sentence/document embeddings?

Do we need to fine-tune for the embeddings to be meaningful at the sentence/document level?

keeeba··on Claude Opus 4.1
Anthropic say Opus is better, benchmarks & evals say Opus is better, Opus has more parameters and parameters determine how much a NN can learn.

Maybe Opus just is better

keeeba··on Software Development at 800 Words per Minute
How have you tested your recall in the long and short term? And what were the results?
keeeba··on Sam Altman Slams Meta’s AI Talent Poaching: 'Missionaries Will Beat Mercenaries'
Just checking my notes here.

This is the same Sam Altman who abandoned OpenAI’s founding mission in favour of profit?

No it can’t be

keeeba··on OpenAI and Jony Ive's "io" brand has disappeared
I want to believe that it wasn’t announced at that time, with that name, purely to detract from Google I/O.

But it’s hard

keeeba··on Math Academy pulled me out of the Valley of Despair
Nice story - I’ve seen you on the leaderboard a few times. Good luck through the rest of Foundations III
keeeba··on Understanding the BM25 full text search algorithm
Nice, also find small classifiers work best for things like this. Out of interest, how many, if any, of the 3million were labelled?

Did you end up labelling any/more, or distilling from a generative model?

keeeba··on Swarm, a new agent framework by OpenAI
Thanks for linking - I know this is pedantic but one might think OpenAI’s models could make their content free of basic errors quite easily?

“Conretely, let's define a routine to be a list of instructions in natural langauge (which we'll repreesnt with a system prompt), along with the tools necessary to complete them.”

I count 3 in one mini paragraph. Is GPT writing this and being asked to add errors, or is GPT not worth using for their own content?
