Drex 1.5 (Free) - access through LLMTR

Drex 1.5 (Free) is 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 131,072 tokens) in one request: a choice from your options, a score along your levels, or the probability that a statement is true, each with its probability distribution. It reads text only. The Structured Decisions documentation covers the request shape and the three question types.
