About this model
Tev1-4B-experimental is Together AI's experimental decision model built by supervised fine-tuning Qwen3.5-4B for structured classification and routing tasks. Given an application state, a question, and between 2 and 24 labeled options, the model selects exactly one option rather than producing a conventional free-form response. It is designed for fast decision-making workloads such as intent classification, request routing, policy checks, moderation, workflow automation, and other closed-set decisions. Tev1 is inspired by Jev-style decision models but retains Qwen's standard autoregressive next-token language-model head, allowing it to run through conventional chat-completions infrastructure. Together AI publishes the training recipe and evaluation tooling, making the model useful both as a production decision model and as a reference for building custom classifiers.
