What’s differentSwitch reasoning on or off; hybrid linear attention and multi-token prediction support long-context self-hosted inference.Tev1 4B Experimental is an experimental decision model from Together AI, a supervised fine-tune of Qwen3.5-4B trained to choose one option from a structured state, question, and list of 2-24...Can turn reasoning off for high-volume requests; Chat Completions tool calls require reasoning_effort=none.
