Q: Is AI incapable of achieving sense of reality?
A: AI can definitely achieve sense of reality at the current stage, but not a universal sense of reality that applies to any scenario.
Q: From a technical perspective, why do shiny/glossy effects occur?
A: Shiny and glossy effects are prominent in terms of signals. Modeling general realistic details is challenging, but current AI has found an approximation. For example, modeling a mountain with every texture and bump is complex, but if the mountain is represented as a combination of shapes, the raised parts might approximate areas with high glossiness.
Q: If we reduce its complexity, can we generate realistic effects?
A: Some models trained on specific scenes at https://chatgptimage.org/ demonstrate very detailed, photorealistic results. However, this is limited to those fixed scenarios.

How to expand to more general scenarios: Using even larger models and datasets. This is how Flux achieves its realistic effects: https://www.reddit.com/r/FluxAI/comments/1erpct2/boundary_be...
