>How do you make sure that the LLM doesn't reward hack a proof using these workarounds?

I'm not sure what you mean exactly? There is no soundness issue here, the fact that `sqrt -1` is defined to be 0 does not have any impact on what statements about `sqrt x` can be proved when `x` is positive.

It just means that if you are working on an intermediate step of a proof and you need the result that `sqrt y >= 0` you don't need to provide a proof that `y >= 0`. If you wanted an intermediate result that `(sqrt y) * 2 = y` then you would still need to provide a proof that `y >= 0`, though.


If sqrt -1 = 0, then (by squaring both sides) -1 = 0, which is clearly unsound.


Right but there isn't a theorem saying `(sqrt x)^2 = x`, there's a theorem saying `x >= 0 -> (sqrt x)^2 = x`


Ah, that makes sense. Thank you. As long as every use of sqrt has such a condition.


For what it's worth I just switched from claude code to codex and have found it to be incredibly impressive.

You can check my history to confirm I criticize sama far too much to be an OpenAI shill.


I'm in the UK, so I access Reddit through an Irish VPN all the time and have never had issues.


Are you logged in? The block is usually for logged out users.


Have you tried old.reddit.com ? I use that exclusively and it doesn’t seem to mind vpns.


>I suspect there is also some decent optimizations on the backend that make it cheaper and faster for OpenAI to run, and those are the real reasons they want us to use it.

I doubt it, given it is more expensive than the old model.


I assume that they mean that OpenAI will now be obligated to pay a lot of that money back to Disney as some kind of licensing fee. No idea if it's true, but that's the only way his comment makes sense.


If I were Disney I would want up front cash from OpenAI at this point.


The carousel of ~progress~ financing continues to turn....


It's not ideal, but at least most of these are only used in the `kernel` crate, i.e. if there's a breaking change to these features it should be fixable without widespread changes.


Use a vpn or avoid the UK


After the first step it isn't 1D any more, so I don't think that visualization is possible


It's possible. It'd just be a 3D visualization and more importantly, stupendously huge. If each cell was a cubic millimeter, the shape would be 3700km wide, and stretch 1/3rd of the way to the moon.


And if each cell was a cubic micrometer (which is a side length 200-300 times smaller than a pixel on a typical screen and 50-100 times thinner than a human hair), it'd still stretch 3.7 kilometers, which is about the length of a commercial airport runway.


I'm having trouble finding a common image file format that has > 32bit resolution fields, fit it in.


That's unfair to Europe. A bunch of AI work is done in London (Deepmind is based here for a start)


That's ok. How could they know that there are companies like Aleph Alpha, Helsing or the famous DeepL. European companies are not that vocal, but that doesn't mean they aren't making progress in the field.

edit: typos


Thats not the point.

Deepmind is not an UK company, its google aka US.

Mistral is a real EU based company.


Using US VC dollars. Where their desks are isn’t really important.


Increasingly where the desks and servers are is critical.

The cloud act and the current US administration doing things like sanctioning the ICC demonstrate why the locations of those desks is important.


That's such a silly argument. X, OpenAI and others have large Saudi investments. In the grant scheme of things the US is largely indebted to China and Japan.


Currency is interchangeable. Location might not be.


An EU Company pays taxes in EU, has a EU mindset (worker laws etc.), focuses more on EU than other countries.

And an EU company can't be forced by the US Gov to hand over data.


London is not part of Europe anymore since Brexit /s


Is it so hard for people to understand that Europe is a continent, EU is a federation of European countries, and the two are not the same?


Europe isn't even a continent and has no real definition (none that would make any sense, anyway), so the whole thing is confusing by design


If Europe isn’t a continent, on what continent are the EU member states sitting on?


Eurasia is the widely accepted answer.


I honestly think it is. The amount of people who thinks Europe and EU are the same thing is really concerning.

And no, it's not only americans. I keep hearing this thing from people living in Europe as well (or better, in the EU). I also very often hear phrases like "Switzerland is not in Europe" to indicate that the country is not part of the European Union.


Switzerland has such close ties to the EU that I would consider them half in.


Isn't London on an island, mr. Pedantic?


So I guess Japan isn't Asian then?


While Japan is part of Asia, and Asia is a continent, Japan is also separated from the Asian continent: https://en.wikipedia.org/wiki/Geography_of_Japan#Location


What's more interesting is that the comment you are replying to mistakenly asked me instead of asking the parent.


I think you missed the joke


Drifted to the Caribbean.


Deepmind doesn't exist anymore.

Google DeepMind does exist.


I think the long term effect will be that photos and videos no longer have any evidentiary value legally or socially, absent a trusted chain of custody.


Yes exactly. And this is kind of already played out with text. The printing press came out, literacy increased. Suddenly anyone could write anything and sign anybody else's name to it. There was a trust crisis. Nowadays, we've just gotten used to it and we look at where text came from instead of just what text says.

For example, I'd rather read a tweet from Paul Graham's account than read a screenshot of a Paul Graham tweet that a stranger emailed to me. In the latter case, the source makes me suspicious, so then I go to a more trusted source, e.g. a reputable news organization, or PG's actually X account.
