Nace AI opens the weights of Drex Max v1, a 27B decision model for agent routing that runs on a Mac
Released Nov 1 under Nace.AI Open RAIL-M, Drex Max returns a probability for every option in one forward pass instead of generating text, so routing, triage and guardrail checks can run locally: a 4-bit build fits 24 GB Apple Silicon Macs, with a Q8_0 GGUF and llama.cpp and Ollama forks for 48 GB machines or CPU. Its 67.52 on Decision Index 0.4 is self-reported, and local Mac and CPU paths are text-only for now.
