TypeSafe AI
TypeSafe AI is an AI lab developing machine-native intelligence infrastructure for automation. The company is building a new class of models called System One Models, designed to be used natively by machines rather than humans. These models are trained with a novel algorithm called Reinforcement Learning for Calibrated Decisions (RLCD), which contrasts with Reinforcement Learning from Human Feedback (RLHF) used for chat models. RLCD aims to produce reliable, calibrated decisions rather than human-like conversation. System One Models return typed outputs that software can directly act upon, with each decision including a calibrated confidence estimate. This allows developers to set thresholds for autonomous action versus human review, and combine decisions in code to build complex workflows. TypeSafe AI claims significant performance improvements, stating that their models are 193.6x faster and 444.6x cheaper than LLMs for System One tasks. The first System One Model is available in early access via a waitlist. The approach addresses issues with RLHF-trained models such as mode dropping, overconfidence, and lack of reliability, which often require humans-in-the-loop. TypeSafe AI positions its models as reliable, fast, and type-safe alternatives for automation, emphasizing decisions over strings.

Problem solved
Current LLMs trained via Reinforcement Learning from Human Feedback (RLHF) are optimized for human preferences and chat, leading to issues like mode dropping, overconfidence, and reliability gaps. These flaws often require humans-in-the-loop, limiting automation. TypeSafe AI solves this by building machine-native models that produce calibrated, type-safe decisions with confidence estimates, enabling reliable automation without constant human oversight.
