TypeSafe AI

AI lab building machine-native intelligence infrastructure for automated decision-making in software.

Overview

TypeSafe AI is an AI lab focused on building machine-native intelligence infrastructure designed to make reliable decisions within software systems. Rather than optimizing for human preferences like traditional LLMs, they've developed a new class of models called System One Models, starting with their first public offering, Jev.

Jev is built on a novel architecture using Reinforcement Learning for Calibrated Decisions (RLCD) instead of traditional RLHF. The model produces typed decisions with calibrated confidence estimates, allowing software to act autonomously when confidence is high and escalate to humans when needed. This approach eliminates hallucinations and provides deterministic, type-safe outputs that integrate naturally with code workflows.

The platform emphasizes efficiency and cost-effectiveness, claiming 193.6x faster performance and 444.6x lower costs compared to traditional LLMs for automation tasks, with pricing at $42 per billion input tokens.
