Six open models. Decisions and spans in one call. Sound on.

Name it. Vela finds it. Decisions and the spans you name, in one call.

Vela 3.0 is a family of six open models for the vLLM Semantic Router, from a 0.3B encoder that reads images to a 27B model. Each one reads a request once and returns the router's decisions and the exact spans you name: personal data, unsupported claims, evidence, entities and relations. Its default router, vela3-fast, is a 380M UltraBERT encoder with the highest public Decision Index of any model up to 500M parameters: 50.36. Across the family, entities are at GLiNER level, and from 4B up classification and relations are at or above every model the GLiFormer paper reports, prompted Gemma-4-31B, GPT-OSS-120B and GPT-5-mini included.

Vela 3.0 is the next step from Vela 2.0: the same system_one interface, scaled at once in backbone, decisions, sizes, modality, languages and tasks.
