Returning from our Top of Mind video series, Gartner Chief of Research Chris Howard breaks down what hallucinations really are, why they happen and what they reveal about how machines think. From multiagent systems to physics-informed neural networks, discover how the next wave of AI innovation is moving beyond prediction and toward precision, all while relying on AI-ready data.

Tune in to discover:

• Why hallucinations happen and what they say about how AI works
• How multiagent systems and PINNs are changing how machines reason
• When to use probabilistic neural networks vs. deterministic tools
• Why not every business problem needs AI
