Simo

Simo is a judgment model that provides calibrated probabilities and values for software decisions.

Simo is the System 1.5 judgment model developed by Temprl Labs. It serves as the judgment layer for software that acts. Users can ask typed questions about text, screenshots, or video. The model returns calibrated probabilities and the values needed to act in milliseconds. It helps users stop parsing essays and start reading probabilities for decision-making.
