  • There's a looming replication crisis in AI research.  (AI Snake Oil)

    More specifically there's a looming replication crisis for any research that involves the products of ChatGPT creator OpenAI, which in reality is anything but open.  OpenAI is shutting down access to its Codex AI, giving researchers three days notice before a hundred scientific papers were consigned to the reproducibility dustbin.

    That site looks interesting; it throws cold water on a number of overheated subjects in the AI space.


  • Nvidia's RTX 4000 SFF is a half-height Ada Lovelace professional graphics card.  (Tom's Hardware)

    Perfect if you need a second graphics card but your special edition Hololive PC case only has half-height slots after the first one.

    It has 20GB of RAM and four mini-DisplayPort ports, delivers roughly the performance of the previous generation's RTX 3070, and uses just 70W of power.  The 3070 itself has 8GB of RAM and uses 220W of power, so that's a pretty substantial improvement.

    The price is, unfortunately, $1250.  It would be quite a good card otherwise.


  • Meanwhole Nvidia's H100 NVL has 188GB of RAM and fills four full-height PCIe slots.  (AnandTech)

    And uses around 800W of power.

    Price is not even mentioned, but if you assume it will cost somewhere between a new car and a new house you won't be disappointed.  If you wonder who is in the market for such a thing, Nvidia's marketing says it offers "12x the GPT3-175B inference throughput as a last-generation HGX A100".

    Yeah, it's aimed squarely at OpenAI.
