Nace AI open-sources Drex 1.5, a 9B decision model that scores options for agents instead of writing text
Drex 1.5 takes a state plus typed questions (choice, yes/no, score) and returns a probability for every option in one pass, with up to 131k tokens of context. Weights are on Hugging Face with llama.cpp and Ollama support, and Nace says it tops the Decision Index among models under 10B.
