Epistemic Stress Test — Muse Spark 1.1 validated by MarCognity-AI MarCognity-AI released Muse Spark 1.1, a model validated using its Skeptical Agent to detect 'epistemic fracture'—the gap between confident-sounding text and verifiable claims. The tool aims to make hidden unverifiable assertions visible in AI outputs. I ran responses generated by the model and passed them through MarCognity-AI’s Skeptical Agent. Not to judge the models. Not to compare outputs. But to make visible what usually stays hidden: the gap between how confident a text sounds and how verifiable it actually is. Even technically correct answers contain claims that cannot be traced back to any source. That gap has a name: Epistemic Fracture.
