About TypeSafe AI

Overview

TypeSafe AI is an AI lab building machine-native intelligence infrastructure for automation. Its first public System One Model, Jev, makes decisions inside software rather than producing chat text.

Jev returns typed decisions with calibrated probabilities and a confidence estimate for each decision, so software can act when confidence is high and escalate for review when it is not. TypeSafe reports Jev costs $42 per billion input tokens and delivers 193.6x faster and 444.6x cheaper workflows than LLMs on System One tasks.

Key Benefits

  • Decisions, not strings: typed outputs that software can act on directly
  • Calibrated confidence on every decision
  • Reliable, fast, and type-safe behavior that is more like code than chat
  • Zero hallucinations: every decision ships with a confidence estimate
  • Reinforcement Learning for Calibrated Decisions (RLCD) training algorithm

Use Cases

  • Automation engineers send Jev structured questions and consume typed decisions in code
  • Platform teams set confidence thresholds for autonomous action versus human review
  • Developers chain decisions in code to build larger workflows
  • Teams building software that must account for uncertainty when acting on model output
