It's a bit unrelated, but I've been wondering if LLM providers are using cache read costs to preserve the illusion of constant output token prices. In reality, the longer your context the more expensive output tokens are, but anthropic and openai both have flat output token pricing.

In practice though as a result of cache reads over multiple turns you will end up paying quadratic pricing anyway.

I find the way that models understand images to be seriously lacking. The root cause of the issue as I see it is that image encoding isn't contextual. The encoder should be aware of the prompt so that it can encode the right things. It seems like this should be something that could be trained into a model.

Fun fact: I once got a security bounty because they sent the 2FA emails through click (some email monitoring SAAS thing) with "view in web" enabled, and it was set up so that the emails under a given template used an auto incrementing ID, so you just had to request a 2FA email and then access it through click's web UI.

I think you're misunderstanding the tank's temperature. The internal temperature is 32C, the external temperature is only 16C (they used thermal cameras to measure the external temp, but when they got closer they read the internal gauge which showed 32C). Groundwater in LA is apparently right around 16C, so the difference in temperature between the tank and the water would be basically 0.

So while I do agree that the evaporative cooling is probably doing most of the heavy lifting (in fact, necessarily so if the water temp ~= the tank's exterior temp), it's not unreasonable to suggest that using colder water would be more effective.

In fact, the wet bulb temperature there is apparently right around 16C, so they've basically cooled the outside of the tank as much as they can using evaporative cooling alone. They can certainly use it to _keep_ it there, but without something else they wouldn't be able to cool it further.

Presumably if there's an exothermic reaction happening internally then the core will continue to rise in temperature based on the temperature gradient through the material forming in the tank. I would assume (since my understanding is that it's some kind of plastic) that it has a fairly low thermal conductivity, so the core temperature will continue to rise as more of it turns to plastic even as the outside is cooled to the same ~16C.

In the limit if they were able to immerse it completely in very cold water (~0C) then the exterior of the tank would also be ~0C (supposing they were able to access sufficient quantities of water). I don't think that's practical of course, but again I don't think it's unreasonable to suggest that cold water would make a meaningful difference.

Yeah that's fair. It does make me wonder what there is that would allow this. Maybe importing some snow machines from Tahoe? :-)

I'm actually a little surprised that a quick search for "refrigerated liquid transport" didn't turn up anything. I would have sort of thought this was something that would exist (just because there are so many random things that are necessary for _some purpose_).

Heat exchange is proportional to the difference in temperature though (in reference to your "or heat exchange"). Colder water would cool faster. The tank isn't at boiling either, so it's not like you'll be able to phase change away a bunch of energy. I guess you'll still get some evaporative cooling, but there's a limit to how much you'll get just from the ambient temperature (the exterior of the tank is relatively cool, presumably because the "gummed up" interior is inhibiting heat transfer)

Ah, that makes sense. It's too bad they can't drill into it to relieve pressure without destroying the integrity of the tank (not that I'd want to be anywhere close to it either).

If they didn't have to worry about it imminently exploding I wonder if they could somehow wrap it with reinforcement (e.g., wrap some high strength metal around the tank to prevent it from deforming when drilled into) and then drill into it to extract the liquid?

One of my other less serious ideas was to helilift a Chernobyl style containment structure around it, but I imagine they don't have one of those just sitting around waiting to be used.

I've generally assumed that AI would make developers get lower compensation because of the lowered quantity of developers required for the same output, but this raises the possibility of it actually increasing if more developers end up doing their own things instead of entering the broader labor market :)

Imo the main benefit of AI is allowing faster experimentation and more parallelism, as well as faster iteration.
