Nace / nace/drex-v1.0-free

Drex 1.0 (Free) - access through LLMTR

Drex 1.0 (Free) is the first version of Nace's decision model, at no charge until 13 October 2026, 23:59 (TRT); it closes earlier if the quota set aside for free use runs out. Free use is limited per account per day. It answers up to 512 typed questions about a state you supply (text or JSON, up to 32,768 tokens) in one request: a choice, a score or a yes/no probability, each with its probability distribution. It reads text only; for a longer state use Drex 1.5. The Structured Decisions documentation covers the request shape and the three question types.
