RL Drives ATHENA to Master Metacognition for Tool Invocation
marinkazitnik · x · 2026-07-07
Research indicates that in therapeutic reasoning, the ability to "know what evidence to look for before reaching a conclusion" can be learned. Reinforcement learning on massive real-world toolsets is a viable path to achieving this. ATHENA's results show that this metacognitive tool-invocation capability distinguishes the model from those that "confidently answer from memory," similar to the fundamental difference between a good doctor and a confident guesser.
