It was 94% sure. So here are the weights.
Compatible with Ollama, Unsloth, OpenCode or plug it into Claude, Codex, Cursor, Hermes, Claw and more.

Drex 2.0 is an open weightsA model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.Full definition → decision model that returns calibrationHow well a model's confidence matches reality — a calibrated model saying "90% sure" is right about 90% of the time.Full definition → probabilities for typed questions instead of generated text, and it runs locally via Ollama and llama.cpp. Useful as a cheap routing or decision layer in AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → pipelines.
