When scaling curves cross, it signifies that one architecture is superior in the data-limited regime while the other excels in the compute-rich regime. You must characterize your target compute relative to this crossing point; if the crossing occurs before your target, extrapolation is more reliable. Additionally, you should investigate the mechanism behind the crossing—such as depth-width interactions or saturation artifacts—to ensure the result is robust rather than a setup-specific artifact.
