Text is a standard sized embedding vector that gets passed one at a time to an LLM. All tokens have the same shape. Each token is processed one at a time. All tokens also have a pre defined order. It is very different and vastly simpler. Serializing 3D models as text is not going to work for negligibly non trivial circumstances.
