The vLLM Semantic Router team has released Decision 2.0 — six open decision models sized 0.6B, 0.8B, 2B, 4B, 9B, and 27B. Multiple questions about one input are answered in a single forward pass with per-option probabilities, aimed at routing and classification use cases.
On the Jev Decision Index 0.3, each model reportedly tops same-size open models they lined it up against. The full set (Vega-27B, Lux-9B, Nox-4B, Sol-2B, Eos-0.8B, Kai-0.6B) is on Hugging Face and trending; Vela 2.0 was also updated.
