powerful \u2014 but fragile.<\/p>\n<p>They perform poorly when tasks require:<\/p>\n<ul>\n<li>Logic or factual correctness<\/li>\n<li>Stability and repeatability<\/li>\n<li>Controlled or explainable

notice when something doesn\u2019t fit.<\/p>\n<p>That\u2019s what makes them stable, predictable, and trusted.<\/p>\n<hr \/>\n<h3>Quick Definition \u26a1<\/h3>\n<p><strong>VAEs are probabilistic
