Aplomb 1

by EmpirioLabs

Aplomb 1 is EmpirioLabs' 5.3-billion-parameter decision model, built on Alibaba's Qwen3.5-4B with an audio encoder from Qwen3-Omni. It reads text, JSON, images, audio and video and answers typed questions with calibrated probabilities rather than generated prose. The model supports a state plus its longest question of up to one million tokens. Questions can ask for a yes/no judgment, a choice among named options, a position on an ordered scoring rubric, or a tool selection. Tool answers include distributions for enum and boolean arguments; free-text arguments remain for the calling application to fill. Questions are evaluated independently, and an optional abstention result represents the probability that the input lacks the information needed to answer. Use it for classification, routing, moderation, extraction checks, agent tool selection and evaluation when software needs an answer with uncertainty attached. Aplomb 1 does not generate text. Its open weights are available under the EmpirioLabs Model License, which places conditions on commercial use and redistribution.
