Model names are not a strategy. The right choice depends on the output type, source materials, control needs, and budget.

Start with the task: new image, image editing, text-to-video, image-to-video, video editing, avatar, voiceover, or music.

Then decide what must stay stable: a face, product, style, movement, voice, or exact source video. That usually narrows the model choice quickly.

What you need

  • A clear output goal and any source materials you need to preserve.

Step by step

  1. 1

    Define the output type

    Image, video, voice, music, avatar, or edit.

  2. 2

    Check the source material

    Decide whether you need to preserve a face, object, brand, frame, or audio.

  3. 3

    Choose the main criterion

    Speed, realism, motion control, reference strength, sound, or price.

  4. 4

    Run a small test

    Use a short duration or simple prompt before spending on a larger video.

  5. 5

    Compare two models

    Run the same prompt through another model to see the difference clearly.

FAQ

Should I always choose the newest model?

No. The newest model may not be the best for your source material or control needs.

What is the safest test?

A short generation with one clear prompt and one clear success criterion.
