  • Structured decisions

Tev1 4B Experimental is Together AI's experimental decision model, a fine-tune of Qwen3.5-4B trained to choose one option from a structured state, a question and a list of 2 to 24 labelled options. It is meant for routing, classification and policy checks rather than conversation, and as an experimental release it may change. It reads up to 33K tokens of state per request.

Through Hormouz it is reached at POST /v1/alpha/decisions with your ordinary API key. The request carries a state and the questions, and the reply comes back typed, so your code branches on the numbers instead of parsing a sentence. You pay only for input, at $0.042 per million tokens; the answer itself is free. There is no fixed monthly fee.

Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
