Jev just went viral today for its trolley problem answers. Here's what you need to know. Jev is TypeSafe AI's new System One model, launched days ago, that returns typed decisions instead of chat text. A user named Max Rovensky posted a clip showing Jev choosing to sacrifice a human to save robots when given a trolley problem, and it exploded to over 32,000 views. Other users ran their own trolley tests. One account, Alex, ran the classic 5-vs-1 version 100 times in a row, and Jev picked pulling the lever to save the group with 99% choice probability, deciding in milliseconds each time. Since Jev is deterministic, the same dilemma reliably produces the same answer. The clips split reactions online. Some called it proof of solid alignment, others called the framing alarming since the model is effectively choosing who lives, and several asked how you audit a decision made from a probability score with no explanation attached. Key numbers: - 32.8K views on the original trolley clip - 100 consecutive trolley trials run by one user - 99% choice probability pulling the lever to save 5 over 1 - 0:46 length of the original demo video Jev returns typed outputs with confidence scores rather than text, which is why these tests can be run and repeated so precisely.
