WhitneyLand··on Fine-tuning now available for GPT-4o
Say I want to ask a model about a code base 500k tokens in size. The questions would not be to generate code, but rather to help understand it in a way that require the model to globally reason about everything at once.

How might performance compare between:

1.) Using a model like Gemini to load it all into context at once

2.) Using one of the various summarization systems/embedding/RAG etc.

3.) Fine tuning the whole code base into Gpt-4o

WhitneyLand··on Ask HN: Why does ChatGPT love the word "eager" so much?
To what extent can this style be overcome by prompting?

If it can be overcome in existing models, it’s probably going to involve different aspects including vocabulary, style, and organization.

WhitneyLand··on MacBook Air, M2 Chip, 8GB RAM: Nothing is open, but half the memory is gone
Well RAM can be an interesting trade off.

Have the last MacBook Pro Core i9 model with 64GB RAM and 4TB SSD and in trying to sell it the prices seem super low way less than 1k.

I bet the M2 is worth way more.

WhitneyLand··on Evaluating a class of infinite sums in closed form
The answer is just 26? That’s crazy.

Wonder if there’s any way to intuit this before working it out.

WhitneyLand··on Australia starts peanut allergy treatment for babies
Ok I’ll bite - Wouldn’t have guessed it necessary to bookend a comment with all caps disclaimers, yet it’s happening, so I’m going to guess you have an interesting or cautionary anecdote around it we can possibly learn from?
WhitneyLand··on The Marshmallow Test does not reliably predict adult functioning
Of course it’s not all intentional. And it may not even be unethical by their standards as far as certain kinds of p-value hacking are allowed and journals are sometimes are hesitant to call out problems.

But there’s been a huge amount of questionable behavior and there has to be personal responsibility with that. It’s not an overstatement to call this part of one of the biggest failures of science in history, and you can’t just sweep that under the rug as unintentional.

As far as pop science I’m not addressing that but those sins don’t exonerate everything else.

I don’t get what you mean about Popper either, he likely would’ve been all over the reproduceability crisis and calling out integrity as a key issue.

Yes, science is self-correcting and things have definitely started to improve after learning from all of this. But the damage has been done. at the time when we need science, the most it’s been discarded by a significant part of the population.

WhitneyLand··on The Marshmallow Test does not reliably predict adult functioning
So in a nutshell, one of the greatest failings of science in history comes down to, researchers were under pressure so they caved and compromise their ethics and morals.

Even worse, the replication crisis is only one reason that the public has continued to lose faith in science in the post truth era.

It’s also the disinformation campaigns that set out to attack whatever’s in a groups interest whether it be politics or the environment.

Maybe the coup de grâce will be social media which encapsulates people into bubbles seemingly impenetrable to the truth.

WhitneyLand··on Large Enough
So, it's conjecture then?

What you're saying sounds plausible, but I don't see how we can conclude that definitively without at least some empirical tests, say a set words that predictably give an error along token boundaries.

The thing is, there are many ways a model can get around to answering the same question, it doesn't just depend on the architecture but also on how the training data is structured.

For example, if it turned out tokenization was the cause of this glitch, conceivably it could be fixed by adding enough documents with data relating to letter counts, providing another path to get the right output.

WhitneyLand··on Large Enough
Where did you get this idea from?

Tokens aren’t the source of facts within a model. it’s an implementation detail and doesn’t inherently constrain how things could be counted.

WhitneyLand··on Is Mars Habitable? (1907)
I guess we have to enjoy the last year or so before better models are indistinguishable from us?

With some better/clever prompting I’m not sure they could be as easily detected now.

WhitneyLand··on Is Mars Habitable? (1907)
Did you write this? Pardon me if you did, but your comment sounds ChatGpt heavy, especially the open call for participation at the end.
WhitneyLand··on Is Mars Habitable? (1907)
Yes it’s a big lesson, not so much in noticing other examples in the past but in thinking critically about present day conjectures yet to be resolved.

So many smart, credible people build up lines of thinking (a necessary step and best that can be done presently) around subjects. These get discussed, reported on, worked with, and very easily become conventional wisdom. Yet so often they turn out to be way off course.

WhitneyLand··on FCC votes to limit prison telecom charges
You’re technically correct, but try to zoom out for a minute and look at the subtlety of human nature.

This topic has fired every one up because it’s unnecessarily cruel, hurts families who didn’t do anything wrong, enriches companies not providing any value, and shows people trying to be “tough on crime” when very ironically they’re probably creating more crime by eroding support systems.

The parent commenter mostly expresses that outrage, and makes a passing comment about business competition.

By this time anything you said that could be perceived as possibly being near the other side of the argument is going to be taken as supporting the other side.

But they are two separate points that can be independently discussed you say? Technically that’s true, but humans don’t work like that.

Always step back and look at the biggest point being made and realize, there may be little room for nuance depending on the context.

WhitneyLand··on Cutting Board Designer
Could you use long strips as the individual pieces and soak each strip in stain for a progressively longer amount of time to create a gradient effect in the final product?
WhitneyLand··on An epigenetic editor to silence genes
>gene therapy of any kind is actually extremely complex

Yet there’s people on YouTube self administering gene therapy to cure lactose intolerance.

Not an endorsement, just to say it’s interesting how easy it’s becoming to do these things.

WhitneyLand··on It's getting harder to die
May I ask if you’ve considered taking measures to end your own life?

I think I’ve had an unusual number of people close to me choose that option, including my father recently so I guess I’m still trying to reconcile it all. Their pain vs mine, what could have played out differently, etc.

I sincerely wish the best outcome for you and yours.

WhitneyLand··on Einstein and his peers were resistant to black holes
Well yes, but they also knew stars collapsed, and that something had to happen in that case. Maybe at first they thought fine, everything becomes a white dwarf or a neutron star.

But then after Oppenheimer did the math in 1930 and showed that collapse into a black hole was within the theory of relativity would you still taken the same position?

WhitneyLand··on Gemma 2: Improving Open Language Models at a Practical Size [pdf]
The paper suggests on one hand Gemma is on the same Pareto curve as Llama3, while on the other hand seems to suggest it’s exceeded its efficiency.

Is this a contradiction or am I misunderstanding something?

Btw overall very impressive work great job.

WhitneyLand··on The First Animal Ever Found That Doesn't Need Oxygen to Survive
No what?

Paragraph 7 acknowledges what the parent comment mentioned, that other species use very little oxygen.

The title says this one needs none. The 2nd paragraph says:

“…it doesn't breathe; in fact, it lives its life completely free of oxygen dependency.”

If that’s not enough, it’s also made clear in Wikipedia:

https://en.m.wikipedia.org/wiki/Henneguya_zschokkei

WhitneyLand··on The First Animal Ever Found That Doesn't Need Oxygen to Survive
No, it addresses that point. Paragraph 7 acknowledges it. Needs no oxygen at all.
WhitneyLand··on Allan McDonald refused to approve Challenger launch, exposed cover-up (2021)
Which executive pressured the engineers, was there any accountability?
WhitneyLand··on Gilead shot prevents all HIV cases in trial
Influenced the deaths of hundreds of thousands of people?

Yet apparently to this day he draws over 200k/yr in salary from Berkeley. I believe they are not entirely funded by tuition/endowments which means California tax payers support him at least in part.

WhitneyLand··on Claude 3.5 Sonnet
I see plenty of praise here for Claude over GPT4.o in writing code but it failed for me.

To add to the collective anecdata, here Gpt 4.o does fine and Claude invents packages that don’t exist:

Question:

“Write code in Swift to use RAG and LLMs to allow users to ask questions about a document collection.

Let’s use services to get the app completed quickly.

What do you think about using Cohere for the text embedding model, and Pinecone for the vector db?”

Output (packages don’t exist):

import Cohere

import PineconeSwift

class RAGService {

private let cohere: CohereAPI

private let pinecone: Pinecone

WhitneyLand··on Nature retracts paper that claimed adult stem cell could become any type of cell
Well, consider this:

- The overall retraction rate is 4 in 10,000.

- Most researchers go their entire career without a retraction

- She now has 4.

WhitneyLand··on The misunderstood Kessler Syndrome
Can’t believe someone wrote that whole article without getting to some basic answers.

What’s the probability of a major collision? What’s the probability that ISS significantly damaged?

It says there’s no consensus from the models, so we can’t know what any of them predict?

WhitneyLand··on Coqui.ai TTS: A Deep Learning Toolkit for Text-to-Speech
Anyone have a sense for how these compare to OpenAI’s TTS?
WhitneyLand··on Scalable MatMul-Free Language Modeling
Am I reading the paper right, or is there any reason not to be cynical about these points?

1) It’s weird to choose linear attention for their implementation because that’s not what their paper is about and they claim no insights relevant to attention mechanisms.

2) By benchmarking all models this way (linear vs linear) it likely inflated their numbers over comparing their removal of matmul in a quadratic vs quadratic scenario.

3) This claim implies a comparison to the state of the art in language models where the standard is quadratic attention, and is therefore a flawed comparison:

“We processed billion-parameter scale models at 13W beyond human readable throughput, moving LLMs closer to brain-like efficiency.”

4) Those type of brain comparisons fall apart under scrutiny, are not standard in ML research and don’t mean much anyway.

5) Right up front in the abstract they make specific performance claims and imply they come from removing matmul, but don’t mention linear attention until section 4 on experiments.

WhitneyLand··on Draw an iceberg and see how it will float
Try something that has no flat surfaces. For example a five pointed star.
WhitneyLand··on Qwen2 LLM Released
Is this supposed to be a joke or hyperbole?
WhitneyLand··on Re-Evaluating GPT-4's Bar Exam Performance
Specifics like this make it much easier to agree on LLM capabilities, thank you.

Automatic proof generation is a massive open problem in all of computer science and not close to be solved. It’s true LLMs aren’t great at it and more is required for example as with the geometry system Deepmind progresses on.

On the other hand they can be very useful to explain concepts and allow interactive questioning to drill down and help build understanding of complex mathematical concepts, all during a morning commute via the voice interface.
