tmalsburg2··on OpenLLM
From the description of the repo: "An open platform for operating large language models (LLMs) in production."
tmalsburg2··on OpenLLaMA 13B Released
I think some of these 13B models may only be pretrained and may not have benefited from RLHF. So it’s not clear how much of the difference is due to parameter count.
tmalsburg2··on Apple Vision Pro: Apple’s first spatial computer
Even if that where possible, I doubt that the accuracy of the eye-tracker is sufficiently high for this approach to work.
tmalsburg2··on Apple Vision Pro: Apple’s first spatial computer
The pixels may be 7.5 microns but you’re forgetting that they are viewed through a lens. The point stands: 4K pixels for the full field of view, which is a lower density than 4K for a small screen.
tmalsburg2··on Apple Vision Pro: Apple’s first spatial computer
4K is not much if you consider that these pixels have to cover the entire field of view, not just a relatively small screen.
tmalsburg2··on GitHub Copilot Chat Leaked Prompt
I’m surprised that these instructions are making such heavy use of negation, explicit (“not”) and implicit (“avoid”). It’s well known [0] that LLMs, like humans, struggle with negation. Some instructions, of course, cannot be easily framed without negation, but in other cases, there are obvious positive alternatives.

tmalsburg2··on GitHub Copilot Chat Leaked Prompt
Yeah, still a bit strange given that GPT4 doesn’t even see individual characters but only tokens.
tmalsburg2··on Org-assistant.el – Org Babel extension for Chat Assistant APIs
Clarification question: When you press C-c C-c on the B block, what is sent to ChatGPT, only B or the whole previous conversation? If the latter, this would break Org Babel semantics. Not necessarily a dealbreaker, but something to be aware of.
tmalsburg2··on CATL has announced a new “condensed” battery with 500 Wh/kg
… in mice.
tmalsburg2··on The end of nuclear power in Germany
I know. But the idea that they'd pop the Champagne now suggests that the closure of the remaining plants was a reason for Russia to celebrate. However, if the phasing out of nuclear in Germany was ever a reason for them to celebrate, they would have celebrated long ago. Also, Russia is a major source of Uranium, so it's not at all clear that this is actually good for them. Further, even 20 years ago, nuclear covered only a tiny part of Germany's primary energy needs (at no time more than 12%) and could have easily been compensated for with coal. So again, it's not clear at all that ending nuclear has pushed the geopolitical needle.
tmalsburg2··on The end of nuclear power in Germany
I doubt it. The share of nuclear power was too small to matter geopolitically, just 5% of electricity.
tmalsburg2··on The end of nuclear power in Germany
The previous year, 2020, is a bit of an outlier, though, due to covid.
tmalsburg2··on The end of nuclear power in Germany
They’re also one of the major sources of Uranium.
tmalsburg2··on The end of nuclear power in Germany
No, Germany does not go the furthest. Other countries have quit nuclear long ago, e.g. Italy closed all plants in 1990 following a 1987 referendum, i.e. 33 years before Germany. Similarly Lithuania. Denmark already decided in the 1980ies not to build new plants.
tmalsburg2··on GPT-4 identifies SVB’s biggest risk & gives good advice using 2021 balance sheet
Plus, given that sampling is probabilistic, one would have to prompt the model many times and evaluate all the responses. When I see examples as in the post, I always assume that the result was completely cherry-picked from a larger samples that contained all kinds of stuff.
tmalsburg2··on Bing AI can play chess
I only tested GPT-3 and it started predicting illegal moves after 8-10 turns or so. When I played unusual moves, it went off rails much sooner and often immediately. If you know of a formal evaluation of GPT-4 chess skills, please post the link. Would love to see it. If it really makes illegal moves only rarely, that would be indeed impressive, but I believe it when I see it :)
tmalsburg2··on DPReview.com to close
I learned a lot from DPReview about photography, but I also learned a surprising amount from them about what excellent writing looks like. Sometimes I read long reviews about cameras that I wasn't even interested in just because the writing was so good.
tmalsburg2··on GNU Octave 8.1
Tons and tons of legacy code in academia. The cost of re-implementing it in Julia or similar is prohibitive.
tmalsburg2··on Running LLaMA 7B on a 64GB M2 MacBook Pro with Llama.cpp
Yeah, 63ms/token (number from the post) is totally usable. Didn't the CPU version that was recently posted take 8min/token? But I think that was a larger model.
tmalsburg2··on Bing AI can play chess
Typical chess programs are specifically designed to play chess. A lot of human knowledge about chess is hard-coded in these programs. These programs are therefore not AI. They play chess and only chess. Bing AI on the other hand was never designed to play chess. It was merely designed to predict the next word in a text, a task that is quite different from chess. If such a program can play chess, that's much closer to what one might call AI, because it learned the rules of chess and chess strategy and tactics on its own. However, let's not get carried away, GPT models do play decent opening moves, but then quickly start predicting illegal moves. What they're doing is best described of having memorized common opening moves and they don't really have any solid understanding of the game.

When you find yourself writing a comment like that, you should pause and ask whether you might be missing something.
tmalsburg2··on Fork of Facebook’s LLaMa model to run on CPU
If someone else wrote this comment, would you find it useful?
tmalsburg2··on The Waluigi Effect
This may happen simply because LLM, like humans, are bad a negation.
tmalsburg2··on Deutschlandticket for regional bus and rail services to be offered for €49/month
We don't need faster trains in Germany. We need trains that are more or less on time. Punctuality is a complete disaster and probably the main reason why people hate taking the train in Germany. If you have a connection that requires changing to another train, the chance that you miss your connection is too damn high.
tmalsburg2··on Deutschlandticket for regional bus and rail services to be offered for €49/month
I don't think that people use cars because it's cheaper. Owning and using a car in Germany is pretty expensive and public transport probably was already cheaper for the vast majority of use cases.
tmalsburg2··on Facebook LLAMA is being openly distributed via torrents
"Potentially" is doing a lot of work here. I'd say that the trained model is worth approximately as much as the electricity that was required to train it.
tmalsburg2··on Facebook LLAMA is being openly distributed via torrents
Why leak it instead of just publishing it along with a press release about openness and democratizing AI and so on?
tmalsburg2··on ArxivGPT: Chrome extension that summarizes arxived research papers using ChatGPT
The training data contains tons of false information and the training objective is simply to reproduce that information. It's not at all surprising that these models fail to distinguish truth from falsehood, and no incremental change will change that. The problem is paradigmatic. And calling people cynics for pointing out the obvious and serious shortcomings of these models is poor form IMO.
tmalsburg2··on ArxivGPT: Chrome extension that summarizes arxived research papers using ChatGPT
In my experience, it's almost safe to assume that the LLM summary will misrepresent the content in some way.
tmalsburg2··on ArxivGPT: Chrome extension that summarizes arxived research papers using ChatGPT
"The best model was truthful on 58% of questions, while human performance was 94%."
