Yeah, if user -> org tenancy is stored in the same database without any similar defence in depth then a fresh API key after updating org would work around this. Would be a interesting topic for them to cover.

I think the same HMAC(pepper, user, org) as a validation column would work. Better yet, encryption with AAD on any tenancy data if you have a TPM available.

The OPs point wasn’t that OpenAis financial situation is comparable to Apples. It was that the likely cost of litigation is a drop in the ocean for OpenAi too despite their comparative lack of cash to burn. Legal disputes like this cost in the hundreds of millions over many years, so well below 1% OpenAis last single funding round in single year. If they got a tiny benefit from this (very gross) behaviour it may be finically well worth while. OpenAI may very well go under IMO, but this will barely be a straw on the camels back.

That’s what they do, but the TPM pepper is also needed for HMACing in their threat model. Otherwise the attacker just adds the victim’s user id to their hashing process too.

Zero data retention was an enterprise agreement that Anthropic and Amazon agreed with customers and delivered on. There’s no way AWS would trade in their reputation with enterprises just to soak up some slop.

I’ve seen whole teams at companies set up fail to provide these booleans-as-a-service well. There are whole companies like LaunchDarkly for them.

If you boil it down to this, you may as well boil down every service that exists to bits-as-a-service.

Turns out theres legitimate business value in these things, and complexity in delivering them.

At least Anthropic claims that they are profitable on a per model basis. But since both revenue and training costs are growing exponentially, and they need to pay for model N training today, and only get revenue for model N-1 today, the offset makes it look worse than it is.

Obviously that doesn’t help them turn a profit, until they can stop growing training costs exponentially.

So it’s really a race to see whether growth in revenue or training costs decelerates first.

Yes, but it’s a common misconception that impact is a bad thing.

The body, including bones, muscles, tendons and joints, adapt to stress. Many people do too little, not too much, as they get older.

There’s a limit to that recovery of course, and balancing it with stress is not always simple.

I also think fsync before acking writes is a better default. That aside, if you were to choose async for batching writes, their default value surprises me. 2 minutes seems like an eternity. Would you not get very good batching for throughout even at something like 2 seconds too? Still not safe, but safer.

Yes, the greenest browser is one that doesn’t use AI. They aren’t claiming they’ve built that though, just the greenest AI.

It’s interesting that the author chose to use SHA256 hashing for the CPU intensive workload. Given they run on hardware acceleration using AES NI, I wonder how generally applicable it is. Still interesting either way though, especially since there were reports of earlier Graviton (pre v3) instances having mediocre AES NI performance.

Yeah, investing in the top companies leads to higher returns for most periods when looking short term.

Over longer periods, the top companies by market cap tend to change though. https://www.investmentnews.com/equities/only-one-of-the-worl...

So if you want to invest in the top companies, you either need to think they won’t change anymore, or you need to find when to buy and sell. Index funds solve this problem for you, albeit with slightly lower returns in the short term.
