Memory is a budget for your model.

Model weights, context and runtime all need space. A “48 GB GPU” does not mean a 48 GB model will fit.

Context + batchWhat it processes at once

Runtime + headroomSoftware and working space

Conceptual allocation only. No model-size guarantee or measured performance claim.
