<p>My experience has been that anything less than a 4-bit quant has a tendency to go off the rails. There’s a threshold of coherency that is being crossed somewhere internal to the model I guess.<p>Try the same prompt with a larger quant (even if it runs very slowly because the model no longer fits in VRAM) & see if Qwen does better - if so, there’s your answer.</p>

<p>Most of the Dimensional ETFs seem to be following some kind of value investment strategy where they take an index but nudge it a bit by some value factor which is claimed to be based on long standing research. It wouldn’t be surprising if this value factor has underperformed in recent years which have been dominated by the rise of growth stocks. The video you link to seems to be talking about these ETFs, although I haven’t dived into the numbers.<p>As far as I can tell the straightforward US & world equity ETFs I’m referring to above don’t have this value bias.</p>

<p>Dimensional runs a bunch of ETFs which are effectively US & world equity index trackers that don’t slavishly follow the indices & can therefore avoid being forced to buy into IPOs or index updates. E.g. DFUS is effectively VTI (IIRC) without the requirement to immediately buy into IPOs that are added to the index:<p><pre><code>  https://www.dimensional.com/us-en/funds/dfus/us-equity-market-etf
</code></pre>
I don’t think they have a QQQ equivalent but I haven’t looked at their entire ETF list.<p>(I have no relationship with Dimensional, nor do I invest in these funds - I just saw them mentioned in a YT video on this topic a few months ago: <a href="https://www.youtube.com/watch?v=mqIHa6URUPk" rel="nofollow">https://www.youtube.com/watch?v=mqIHa6URUPk</a> )</p>

<p>This was a laptop, so cooling was very constrained. The fans can only be so big & you can only shift so much air in & out of a MacBook.<p>I presume Apple knew perfectly well but wanted the halo product to sell to those people who will always pay extra for the perceived “top of the line” product. Once Intel branding had created an i9 that was a bigger number than an i7, then Apple was going to sell it.<p>It was faster than the i7 after all: just not for very long!<p>My entirely speculative theory is that the poor thermal characteristics of that era of Intel CPUs didn’t really become apparent until quite late in the development process & by that point Apple had probably committed to buying a fair chunk of Intel’s output.</p>

<p>The i9 was notorious. Would thermally throttle almost instantly & for any sizeable build job would end up slower than the i7 IIRC.<p>Intel really made themselves unpopular with Apple during that period.</p>

<p>I know this is kind of old hat by now, but it kind of blows my mind that I can upload a hand drawn decision tree & get a transcribed dot file back on consumer hardware using a pile of linear algebra that wasn’t even particularly specialised for this purpose, it’s just a capability that it picked up along with everything else during training.</p>

<p>> Is bread really.. always served?<p>At any kind of formal dining? Yes, absolutely, I would expect there to be a bread roll & a pat of butter served at the beginning of the meal. Both in restaurants & formal dinners in my experience.<p>It's not an absolute rule though & you generally wouldn't expect bread to be served like this at home in the UK. I think the French are more likely to serve bread at home as well.</p>
