    They do heavily use AI, but you haven’t refuted their point that if inventory is in SQL, storing reservation in a second storage system increases complexity.

    Yes, this is a great point and it’s even one that the Cerebras CEO spruiks for his own chips. Talaas has gone furthest on the spectrum here, so seems to have the most potential to …

    Taalas is developing this, but not for Frontier class models. I hope that if we can least get the easy 80% of work done on that sort of hardware, we can greatly reduce the demand f…

    They’re not using ciphertext in inference. They are encrypting agent responses on their servers if it’s going to a subagent on the client. The subagent will send it back to their s…

    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 interest…

    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 compara…

    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 enterprise…

    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 m…

    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 train…

    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, a…

    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 …

    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…

    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. h…

    Runtimes with garbage collectors typically optimize for allocation, not deletion.

    While they don’t specify it sounds like they don’t even require 2FA to access their systems?

    Tangential to the authors point, but it’s funny to note many new SQL databases(e.g CockroachDB, TiDB, MyRocks) are written on top of RocksDB, a “NoSQL” key value store.

    When it comes to cache invalidation worse performance isn’t the primary concern in most cases, correctness is.

    It’s usually a safe bet that the state will preference companies over both employees and taxation unfortunately.

    I think this architecture would be really powerful paired with the actor model to shard databases to nodes.

    At big tech companies I’ve seen and heard about, the answer is crypto shredding. Encrypt all PII at rest with a per user data key. GDPR deletion requests can then delete the data k…
