Create three separate tasks for a comparison: "LOW | My test", "MED | My test" and "HIGH | My test". Use GPT-6 Astra at low, medium and high reasoning effort respectively, if supported here. Keep the speed setting identical. Verify and report the effective model and effort; labels alone are not enough.

Give all three the identical assignment below in fresh isolated folders. Do not include other runs or their outputs. Keep discretionary delegation disabled. Give each up to [TIME LIMIT] for a first attempt. Preserve its output before any follow-up. Record completed work, missing requirements, blockers, elapsed time and attributable usage when available.

Run in parallel only if their tools and workspaces are isolated; serialize any shared computer-control workflow. Monitor progress without coaching. If this environment cannot create tasks or set their effort, tell me precisely which step I must do manually. Never silently substitute settings.
