To illustrate the strength of instantiating Prefabs at run time, here are some basic situations where they are useful: Building a structure out of a single Prefab by replicating it multiple times in different positions, for example in a grid or circle formation. The Prefab contains a mesh, a Rigidbody, and a Collider, so it can fly through the air and detect when a collisionA collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. Big files can slow down Unity project imports or Asset re-imports, because you have to run the DCC software you use as a background process when you import the model into Unity.

Some common examples of Prefab use include: Environmental Assets - for example a certain type of tree used multiple times around a level (as seen in the screenshot above). What you are looking at is the number of vertices/triangles actually being sent to the GPU for rendering. Rather than trying to modify the intact version of the GameObject (such as removing scripts, adding Rigidbody components and so on), its often much more efficient and effective to delete the entire intact GameObject and replace it with an instantiated destroyed Prefab. If you unpack a Prefab that has nested Prefabs inside, the nested Prefabs remain Prefab instances and still have links to their respective Prefab Assets. Just FYI, FBX files themselves are not included in a build--no source files of any kind are ever included. DirectX12: [macOS] Editor freezes when saving prefab changes in Play Mode if "VSync" is enabled ( UUM-30173) DX12: Fixed a case where creating and destroying Renderers that use Dynamic Geometry as Ray Tracing Mode very often in ray tracing effects would cause the GPU memory to fill up quickly.
