This is highly dependent on the workloads you run.
A few recent examples:
•Explain a small code base: 1 OCU
•Running a regular VM (4vCPUs / 16GB RAM) for one hour: 1 OCU
•Explain a large, complex code base: 3 OCUs
•Create a new web app from scratch: 4 OCUs
•Fix a bug in a large, complex code base: 5 OCU
•Running a GPU VM (16 vCPUs / 64GB RAM) for one hour: 7 OCUs
•Adding a new feature to a medium-sized code base: 8 OCUs
Keep in mind that there is a large variability in the number of OCUs consumed for each task.
