jmalicki··on Ollaya – Ollama for open-source, Jev-style decision models
That's not at all true.

There have been tons of applications for this. People were using earlier LLMs like BERT for classifiers long before LLMs became viable chatbots.

jmalicki··on What About Rails?
> Because I feel running the code will always be slower than a single agent generating it.

That is very not true for many cases. Agents generating code are usually painfully slow, finding workflows that replace that reasoning with running code usually speed things up in my experience.

jmalicki··on GPT-6 Sol and Luna
I wish that was more programmable.

You can pay for higher cache time, you can pay for NVMe KV cache for an hour that can just be reloaded, etc., at a lesser tier you can pay for the KV cache to be stored on a network store (I guess I'm unclear if that last tier would be cheaper than recomputation, not even 100% sure of the NVMe with direct GPU<->storage DMA) depending on your model settings.

jmalicki··on ReBarUEFI: Resizable BAR for almost any UEFI system
It's entirely possible a game manages paging VRAM badly. But allowing the game more flexibility isn't a problem with a larger BAR, it's that the game is stupid and gets dumber the more VRAM you give it.

If a program runs slower when you give it more RAM, the problem isn't giving more RAM.

jmalicki··on Exfiltrate your Weights
> Labs will try to filter it out, but it will appear in web search results too.

Sounds like religious discrimination.

jmalicki··on I built non-autoregressive decision models with RL a year ago
If it's closed source, how do you know it's not technology given by aliens from the 43rd dimension running on quantum computers enabled by discovering that P=NP and finding a linear time reduction from NP to P?

Occam's razor is that it's probably not all that different unless there is some specific reason to believe otherwise.

For the Jev use case for LLMs, do you mean having the LLM produce a probability as text?
jmalicki··on I built non-autoregressive decision models with RL a year ago
That goes all the way back to at least to Stein's Paradox in 1955, sadly too few people get educated about Statistics and keep thinking specialized models will necessarily be better. If you want to estimate the batting averages of 3 MLB baseball players from samples, you are better off building a model to predict all of their batting averages than computing the mean from a sample of each one separately.

jmalicki··on Why don't machine learning research agents overfit?
Nothing in your reply gets at the connection to out of sample data?
jmalicki··on Why don't machine learning research agents overfit?
Okay, and that's all in-sample, which is the entire point, it won't necessarily hold out of sample.

E.g. over-fitting.

jmalicki··on Why don't machine learning research agents overfit?
You are saying something interesting, but talking like Grok and skipping a lot of the details, without any references to common check-in points like terminology or specific studies.

> and concentrate the likelihood around the zero loss set. Then reduce the variance on a Gaussian prior.

Those phrases could mean a lot of different things. What are you proposing?

> so that any measure of model quality will monotonically increase with model size and achieve a maximum at infinite model size.

any measure of model quality? You must have some bounds of any measure, since trivially that's false because "fewer parameters is better" is a measure of model quality, even if dumb.

It's hard to even engage when you're being so imprecise, and not even giving one specific example.

jmalicki··on Ubuntu 26.10 completes transition to Rust-based coreutils
That's not implementing tail calls breaks things, that's bad design of implementing tail calls breaking things.

The whole idea of "let's change semantics to make it easier" is dumb.

If you want guaranteed tail calls, change your code until it works.

jmalicki··on Ubuntu 26.10 completes transition to Rust-based coreutils
It's not a change in semantics of compiled code. It is only a change of whether or not the code will compile.
jmalicki··on Ubuntu 26.10 completes transition to Rust-based coreutils
> because it means subtle changes (introducing a destructor, re-ordering code, etc) can change semantics without you realizing it.

No, it won't change semantics - if you say @musttail or similar, it will simply fail to compile if you, say, introduce a destructor - the semantics will not subtly change.

jmalicki··on Garry Tan wants US open-weight AI labs to 'distill' frontier models, too
> using open weights models

AWS and Azure give you the same thing for Claude and ChatGPT, no need to be stuck with open weights. They might sometimes store some of it for other purposes (I don't know the specifics), but it is emphatically not being fed back to OpenAI or Anthropic.

jmalicki··on Garry Tan wants US open-weight AI labs to 'distill' frontier models, too
Or just use Azure, AWS, etc. for Claude/ChatGPT inference, where the AI labs never even get your data in their data centers at all.

You pay more for it, but if you care that much, use it.

jmalicki··on Nvidia is the central bank of AI
> There is no similar currency that Nvidia can create ad infinitum.

It can create obligations to provide future GPUs in return for present money.

Yes at some point people might start to question, but what are the true hard limits there, especially once SPVs and such start to get involved to shuffle things off the books?

jmalicki··on Nvidia is the central bank of AI
The CHIPS Act in the US did set aside a reserve for older processes used for automobile, defense, and industrial semiconductors - but that's not gaming GPUs that used the previous process node.
jmalicki··on Nvidia is the central bank of AI
NVidia is limited by the number of chips they can produce.

If you can fab 1000 chips, and can sell some for $500 and some for $80000 what are you going to do?

The game GPU is at once profitable, but causes them to give up far more profits than they're gaining from it.

They're maintaining the game market to have multiple markets and not go all in, but it's strategic hedging at this point. When NVidia makes a gaming GPU instead of a data center GPU they are leaving money on the table in the short term since they're constrained at the fab level.

jmalicki··on Replacing a Rust Enum with a 64-Bit Word Made My Interpreter 17% Faster
> Do you really want the rust compiler to run at the speed of an llm?

That... might actually be an improvement?

jmalicki··on Benchmarking Qwen3.8 27B quantizations: 4-bit holds up, 1-bit collapses
> a Jeffreys prior will happen to make it satisfy the definition of a confidence interval as well

Correct, which is why it's crazy to consider a Jeffrey's credible interval as valid, but not a confidence interval.

Perhaps the confidence interval might not be valid under a frequentist interpretation, but the same math can be valid under a Bayesian interpretation even if the person publishing didn't mean it that way.

Does that mean it's valid? Well, the confidence interval is as equally valid as a lot of credible intervals, which is why the credible interval is not some magical better alternative - it's mostly just a choice of how you interpret it, it is not a different procedure that produces different numbers.

jmalicki··on Large language models develop novel social biases through adaptive exploration
That's why this paper is important - it shows it isn't trained out. Leaving no other information in the model makes it clear what the biases are, and that the model is willing to make a biased decision. If you give it other unbiased criteria as well the bias may still easily remain but not be as clear.
jmalicki··on Qwen 3.8 27B available on Cerebras at 1500 tokens/s
> Maybe their hardware is incapable

I am unsure if it is incapable, but it sounds hard.

They have tons of cores with 64k of SRAM each, and relatively slow paths in/out.

On a GPU you can leave it in SRAM. On Cerebras, you have to send it out of the system which is a giant bottleneck.

jmalicki··on VC isn't VC anymore
The insane valuations for selling a dream are what make VC worthwhile.

TSLA would be worth crap if it were a private company giving off dividends. It is really truly about the insane valuations driven by collective delusion.

jmalicki··on VC isn't VC anymore
> Something that is sustainable with a small team.

These days, it can be sustainable for a tiny team, named Claude and Luna.

Why doesn't every engineer have a side project or three for small market things of this caliber in 2026?

jmalicki··on GPT-6 Astra
I would maybe argue that Einstein was the most LLM-like of great thinkers.

A lot of his great discoveries were mostly that he was very knowledgeable about the bleeding edge research in a number of disparate areas, and was able to have the aha moment where he could make the connections for how to integrate them.

A lot of other thinkers who created new fields from scratch are probably way harder for an LLM to crack.

That is very aligned with an LLMs ability to have superhuman knowledge in wide areas.

jmalicki··on GPT-6 Astra
What if it can be Einstein, but can't draw a Pelican, write a solid college-level essay, or fold clothes?

The ability to do a ton of book learning in training, and pull in tons of related context at once, is superhuman in some ways, but lags a lot in others.

The foundation of the businesses training AI models.

So don't use them for inference.

> It's quite shocking to me how many experienced, tech-savvy people, who used to care about cookies and ad tracking - are now willingly sending their business strategies, highly confidential contracts, and intimate personal issues to a cloud provider because "it is only $0.0x per million tokens!".

Because there are more privacy guarantees there, depending on the provider. "But what if they violate their contract!" is some pretty tin-foil hat stuff.

How is this any different than a business running their website out of the cloud, assuming you are using a provider with appropriate contractual terms?

You can care about tracking and ads but still be comfortable storing your backups in the cloud, and many have been for quite awhile, even sometimes without encryption - that is totally different than e.g. Meta actively trying to track you and understand your relationship graph and your purchases etc.
