## Summary

The vLLM Semantic Router team releases d3-ultra, a 26.09B-parameter dense multimodal decision model under Apache-2.0 that returns answer probabilities rather than generating text. The team reports 87.2 on its own SR-Text test, ahead of GLiDE V1.2 at 85.1, and 58.2% on SR-Box across 10 domains, behind d3-turbo at 60.0%. The model supports 131,072 tokens of context per question and is available through Transformers, vLLM Semantic Router, a free API, or a Hugging Face Space.
