Drex 2.0 is a small decision model from Nace.AI with a 131K-token context window, built to make decisions rather than generate text. Given a state and typed questions (yes/no, multiple choice, or score), it returns a probability for every option in a single forward pass, making it a fit for routing, classification, tool selection, and policy checks that need a scored answer instead of prose.
On-demand deployments allow you to use Drex v2.0 on dedicated GPUs with Fireworks' high-performance serving stack with high reliability and no rate limits.
