The original post, translated
TypeSafe AI announces that Jev is officially open to everyone, removing the waitlist. Users can now directly register and use it on the official Console, without needing to apply for Early Access. Jev is not responsible for chatting or writing code, only for classification, scoring, and judgment. Developers define the output range and structure in advance, and Jev directly returns the judgment result, probability, and confidence, allowing the program to take the result and continue execution.

Where this case fits
