<p>Linux and Chromium seem at the edge of the current scale of "ordinary" open-source software. I think perhaps one should also take into account how much money would be needed to be able to build the thing in reasonable time.<p>Building Chromium sounds awful, but I'm not sure I'd really need to buy another computer for that. If I did I'm sure I wouldn't need to spend billions on it, most probably not even millions.<p>For LLaMa I definitely don't have the computer to build it, I definitely don't have the money to buy the computer, even if I won the lottery tomorrow I'm pretty sure I wouldn't have enough money to buy the hardware, even if I had enough money to buy the hardware I'm still not sure I could actually buy it in reasonable time, nvidia may be backlogged for a while, even if I already had all the hardware I probably wouldn't want to retrain llama, and even if I wanted to retrain it the process is probably going to take weeks if not months at best.<p>Like I think it's one of those things where the difference in magnitude creates a difference in kind, one can't quite meaningfully compare LLaMa with the Calculator app that Ubuntu ships with.</p>

<p>To be fair if they released detailed instructions and datasets on how to rebuild llama (considering that there's some randomness in the process) you still probably wouldn't be able to build it, like who has the resources? And if you had the resources you probably _still_ probably wouldn't _want_ to rebuild it yourself, it seems awfully expensive when you could instead spend those resources elsewhere.<p>Fair point about the license, people have different definitions for what "open source" means.</p>

<p>Apparently I can find some matches for games that start like that between very strong players [1], so my hypothesis that the model may just be predicting bad moves on purpose seems wobbly, although having stockfish at the lowest level play as the supposedly very strong opponent may still be throwing the model off somewhat. In the charts the first few moves the model makes seem decent, if I'm interpreting these charts right, and after a few of those things seem to start going wrong.<p>Either way it's worth repeating the experiment imo, tweaking some of these variables (prompt guidance, stockfish strength, starting position, the name of the supposed players, etc.).<p>[1]: <a href="https://www.365chess.com/search_result.php?search=1&p=1&m=8&n=3071&order=welo&ms=e4.e6.d3.c5.Nf3.Nc6.g3.Nf6&rev=&wid=&bid=" rel="nofollow">https://www.365chess.com/search_result.php?search=1&p=1&m=8&...</a></p>

<p>It's probably worth to play around with different prompts and different board positions.<p>For context this [1] is the board position the model is being prompted on.<p>There may be more than one weird thing about this experiment, for example giving instructions to the non-instruction tuned variants may be counter productive.<p>More importantly let's say you just give the model the truncated PGN, does this look like a position where white is a grandmaster level player? I don't think so. Even if the model understood chess really well it's going to try to predict the most probable move given the position at hand, if the model thinks that white is a bad player, and the model is good at understanding chess, it's going to predict bad moves as the more likely ones because that would better predict what is most likely to happen here.<p>[1]: <a href="https://i.imgur.com/qRxalgH.png" rel="nofollow">https://i.imgur.com/qRxalgH.png</a></p>

<p>Yes exactly, at some point I asked to maintain it and kinda redid it. Now I kinda consider it "done", as in "maybe some more work would be put into it, but by end large I don't think it's going to change in the future".</p>

<p>This seems a bit different from the kind of signals frameworks have, where dependencies are tracked automatically (no dependency array), and you can sort of chain stuff automatically, so for example you can have an effect that depends on 3 memos that depend on 4 signals or whatever else, and you never experience non-fresh values.<p>If you want to look a bit deeper into this I had written another sort of toy implementation that much more closely resembles what the frameworks are actually doing: <a href="https://github.com/fabiospampinato/flimsy">https://github.com/fabiospampinato/flimsy</a></p>

<p>I would guess that having 2 zeros is not that useful for NNs, but in general with 2 bits we could encode 4 states, so are there 4 possible states that would be useful to encode? Sure, but would this be better than encoding 3 states? That's the entire question imo. I would guess that 3 states are probably better, because negative/neutral/positive seems the minimal signal that we need these weights to provide.</p>

<p>It seems tough to do, besides I'm not sure what the benefit would be, with that you can't do the optimized matrix multiplication anymore, and if you need more precision presumably you can just add more neurons and/or train for longer and/or with better data.</p>

<p>> 1) I never knew how much I disliked naming things before I didn’t need to do that anymore<p>I never understood this argument about naming. You need to name the component anyway just to be able to reference it somewhere? You need to give the folder or the file where this component is defined a unique name anyway? Internal nodes technically don't need to be named when using Tailwind, but if for example I'm writing a Slider component, do I not want to name the "handle" thing that can be dragged anyway? How was finding the "handle" word a non-insignificant hurdle? And if I need to talk about this element with a colleague what would you call it anyway?</p>
