The Key Insight
Many tools still default to older, less capable models. Always check which model you are using.
The difference between an F-tier and A-tier model can mean the difference between a frustrated user and a delighted one.
Higher-tier models are not always necessary. Match the model to the task: use C- for quick drafts, B- for daily work, and A- when quality and nuance matter most.
