Can you add VRAM across rented GPUs?
Adding the memory capacities gives the physical total, but it does not prove that your application can use the memory as one pool. Check the application’s supported model-parallel or sharding method before selecting a multi-GPU node.
The model pages shortlist single-GPU memory scenarios. They do not promise that a model exceeding one card’s VRAM will run merely because several cards have enough combined memory.
Use the job cost and fee table, model memory estimates, training calculator, and price trends for the relevant inputs.
