Drex v2.0
A specialized decision model introduced by Nace.AI, belonging to the System One model category, which scores candidate answers directly through a pointer head and outputs a probability distribution rather than generating natural language text, supporting yes/no questions, multiple-choice questions and rating questions.
Timeline (last 90 days)
Nace.AI released Drex v2.0, a small decision model that outputs judgments rather than prose, launched via OpenRouter hosting.
Drex v2.0 supports three question types: yes/no questions, multiple-choice questions and rating questions, returning answers with probabilities for each item.
Drex v2.0 is priced on OpenRouter at a 131K context window, $0.06 / 1M tokens for input, and free output.
Drex v2.0's API contract /v1/systemone is exactly the same as TypeSafe's Jev, so decision-calling code written for Jev can switch to Drex with almost no changes.
Nace has not yet said whether the hosted version Drex v2.0 uses exactly the same architecture as the open-source Drex DLM.
