Am I understanding the OpenGL ES program correctly?

Question

OpenGL

Hello, I'm learning OpenGL, and recently the question arose, if I want to draw several different models with different shaders, for this I need to create a program for each model or do I need to use one program for all models, and just link new shaders to it every time?

I will also write the answer here: the process of creating, linking and compiling a program is a long process, so doing this every frame will be a very costly action. So for each mesh there should be its own program or if the shaders do not differ, then it is possible to use one program (The last sentence is my additions).
