 As stated above and shown in the image above, you pay for these resources as long as you consume them. This happens when the image of your notebook is pulled, during the `STARTING` phase, but also during `RUNNING` and `STOPPING` phases, until you reach the `STOPPED` phase.

 ### Pricing examples
 
-#### Example 1: one GPU notebook for 10 hours then deleted
-
-We start one Quantum Notebook, with two GPUs and we keep it running for 10 hours then we **delete it**.
-
-- compute resources: 2 x GPU NVIDIA V100s (1,93€ / hour)
-- remote storage: nothing
-- duration: 10 hours then deleted
-
-Price calculation for compute: 10 (hours) x 2 (GPU) x 1,93€ (price / GPU) = **38,6 euros**, billed at the end of the month.
-
-#### Example 2: one GPU notebook for 10 hours but stopped, not deleted
-
-We start one Quantum Notebook, with two GPUs and we keep it running for 10 hours then we stop it and finally we **delete it after 10 days**.
-
-- compute resources: 2 x GPU NVIDIA V100s (1,93 / hour)
-- remote storage: nothing
-- workspace storage: 100GB used. The first 10GB are free.
-- duration: 10 hours then stopped for 10 days
-
-Price calculation for compute : 10 (hours) x 2 (GPU) x 1,93 (price / GPU) = **38,6 euros**, billed at the end of the month.
-Price calculation for workspace : 90 (GB) x 0,01€ (price for object storage / GB) = **0,9 euros**, billed at the end of the month.

-#### Example 4: 15 CPU notebooks for 5 hours then deleted
-
-We start 15 Quantum Notebooks, each of them with one vCPU
-
-- compute resources: 1 x vCPU (0,03€ /hour /cpu)
