General models: compare how they work, not just who made them
These six models emphasize different things: deep reasoning, sustained autonomy, speed and cost, structured output, or work across tools. Narrow by job, then use the primary source to check API, price, and limits.

Creative and interactive models: choose by the output you need
For images, separate generation from revision. For video, check duration, sound, and reference control. For voice, distinguish a live agent from expressive speech synthesis.

From choice to execution
Turn a model choice into a reproducible result
When the next job is cost comparison, API integration, a creative workflow, or debugging, the guide library turns one concrete problem into steps you can run and verify.
