Introduction
Selecting the right AI model involves balancing speed, output quality, and operational cost. For CTOs and PMs, these factors directly impact team productivity and budget efficiency.
Why Speed and Cost Matter for CTOs and PMs
Speed influences user experience and integration feasibility. Cost affects long-term scalability.
- Faster responses reduce wait times in applications.
- Lower costs enable broader deployment without overspending.
