This is a WorkBuddy model-information episode, not a case-based Word lesson. It explains the temporary Hy3 promotion through August 31 and how model choice affects task quality and quota use.
Use the window to practice documents, Excel, presentations, code, and workflows, while checking the current product page because promotions and quotas can change.
A practical selection rule
Choose based on task complexity, context length, tool use, reasoning needs, and the risk of a wrong result. Lightweight tasks do not always need the strongest model; high-impact reasoning and code tasks may.
Treat pricing and promotional terms as time-sensitive product information, not as a permanent guarantee.
Describe the task goal, input materials, risk level, and acceptance checks first. Then choose an appropriate WorkBuddy model, run the task, and verify both the result and the current quota rules.
