    I thought this couldn’t be true, so using one of the newer models (4bit flux) I told it to make a 5 sided star, and then put lines around the outside

    lol this is very weird, did they forbid it from looking at pentagons in the training data or something? it can’t do The Pentagon either, it gives it 8-12 sides instead




  • I’ve been looking at the paper, some things about it:

    • the paper and article are from 2021
    • the model needs to be able to use optional data from age, family history, etc, but not be reliant on it
    • it needs to combine information from multiple views
    • it predicts risk for each year in the next 5 years
    • it has to produce consistent results with different sensors and diverse patients
    • its not the first model to do this, and it is more accurate than previous methods

    It had no payload on any of its flights. Rockets that have enough time/money put into development to have a reasonable expectation of working on the first try (and don’t have such an ambitious design) normally launch with a payload on their first flight. Sometimes, even those fail on the first few flights. Having the first few of a new rocket design fail before reliability is achieved is common (ex: Astra) and SpaceX’s other rocket, the Falcon 9, is known as the most reliable rocket, I even suspect it achieves landings more often lately than most others do launches.

    Starship’s last launch went decently well, reaching orbit (which is as far as most rockets go!) but failing during reentry. It is also supposed to be the rocket with the largest payload capacity to low earth orbit, with 100-150 tons when reused and likely 200-300 when expended.

    The funny thing is that NASA contracts the same companies as the military anyways (in the modern day, at least)

    NASA Prime Contractors Aerojet Rocketdyne, Boeing, Jacobs, Lockheed Martin, and Northrop Grumman currently have over 3,800 suppliers contributing to Orion, the SLS rocket, and the lunar spaceport at Kennedy.

    It gets slightly less funny when you realize that that’s the reason Nasa’s latest rocket made primarily from Space Shuttle parts is way more expensive than basically any commercial rocket. Essentially Congress only agrees to fund NASA if it means they also get to fund these military contractors.
