ChatGPT pioneer launches Jev model for programmatic logic

TypeSafe, a startup founded by ChatGPT co-author Diogo Almeida, emerged from stealth and introduced the Jev model. It outputs typed structured values instead of text, operates with a latency of 70–500 ms, and costs $0.042 per million input tokens.

• The model is trained with RLCD for calibrated decision probabilities
• Parallel sampling speeds up execution up to 193.6 times versus chat models
• Input costs $0.042 per million tokens, output tokens are not charged
• Supports up to 255 discrete choices in a single request
