DiffusionGemma 26B-A4B turned into a local System One fast-decision model via vLLM patch

Someone is porting Google's open DiffusionGemma 26B-A4B into vLLM as a locally running "System One" reflex model built for fast structured decisions instead of paragraph generation.
Unlike autoregressive LLMs that generate token by token, DiffusionGemma operates over a token canvas with bidirectional attention, filling predefined answer slots in parallel — ideal for yes/no calls, A/B/C routing, tool-call selection, and 1–4 severity classification.
The vLLM patch can return bounded choices, probabilities, confidence/uncertainty, and multiple simultaneous decisions, effectively a local AI reflex system.
