Key takeaways
- Jev delivers fast, parallel probability output for structured decisions.
- System One Models aim to be more reliable than LLMs with calibrated probabilities.
- TypeSafe AI claims Jev is 40x–200x faster for high-stakes decision tasks.
Two years in stealth, TypeSafe AI just dropped Jev. The first System One Model—AI built for fast, efficient decision-making.
40x–200x faster. Two orders of magnitude. Parallel probability output, not sequential token generation.
Jev outputs probabilities in parallel. For structured tasks—this looks like a fundamental advantage.
System 1 thinking: fast, intuitive, automatic. System 2: slow, deliberate, effortful. TypeSafe AI believes System One Models can be made more reliable than its alternatives.
It’s more reliable. Calibrated probabilities. Just calibrated decisions with epistemically honest probabilities.
Jev gives you a number you can trust. For high-stakes decisions—that’s a game-changer.
It’s System One Models as an alternative to LLMs. Just fast, reliable decisions.
