Compare AI models side by side in the Playground

Run any image, video or audio model in the Percify Playground, or give two models one prompt in Compare. Each run shows its credit price first.

The Percify Playground lets you run image, video and audio models one at a time or two at a time. Pick a model, fill in its inputs and press Run, or open Compare to send the same prompt to two models and watch both results side by side. Every run shows its price in credits before you start, and a run that fails is refunded.

Open it at app.percify.io/home/playground. You can browse the models without an account. You need to sign in to run one.

How do I run a single model?

1. Find a model

   Open Playground in the sidebar. Sort the catalog with Discover, Trending or Latest, type in Search models, or use the video, image and audio icons to filter by what the model makes. See AI models in Percify for the full list.

2. Fill in the inputs

   On the model’s page, the Playground tab shows an Input form built from that model’s own settings, such as the prompt, a reference image, length or resolution. You can also edit the same values as JSON. Reset puts every field back to its default.

3. Check the price and run

   The header shows the price for your current settings, and the button reads Run with that number. If a required field is empty, Percify tells you which one before anything is charged.

4. Save the result

   The result appears under Output. Use Download to save the file or Copy link to copy its URL.

Each model page also has an Examples tab with sample outputs (press Use input to load an example’s settings into the form) and a README tab that lists every input and explains how the model is priced. Some model pages also have an API tab with ready-to-copy requests. To run models from your own code, see the API reference; API access is included on the Scale and Ultra plans.

How do I compare two models side by side?

1. Open Compare

   In the Playground, press Compare at the right of the header.

2. Choose what to test

   Under What do you want to test?, pick Video models or Image models. Under Comparison type, pick Two models to test two models on one prompt, or Director mode (explained below).

3. Pick the models

   Choose Model A and Model B. If either model needs a starting image, upload one under Reference image.

4. Write the prompt and set the shape

   Type your Prompt, then set Ratio (9:16 or 16:9), Quality (Cheapest, Balanced or Best) and, for video, Duration. Compare only offers durations that both models can make exactly, so the two clips match in length.

5. Run both

   The total reads “credits for both”. Press Compare. Each side shows its own progress, time taken and credit cost.

Compare can only give a model a prompt and one reference image. Models that need an audio track, a source video or two different images are left out of its model lists.

What is Director mode?

Director mode keeps the model the same on both sides and compares two ways of writing the prompt. You pick one model, then a Director A and a Director B. Each director is an AI language model that rewrites your idea before it goes to the video or image model, in one of two styles:

Style	What the director writes
Enhanced prompt	Your idea rewritten as a detailed, production-ready prompt
JSON direction	A structured treatment covering scene, camera, lighting and pacing, sent to the model as JSON

The directions each side used are shown under the results, so you can see what produced each clip.

What can I do with a finished comparison?

• History keeps every comparison you run, so you can open a past one later or remove it.
• The share button creates a public link to the comparison. Press it again to revoke the link, which stops the old link working.
• When both sides are done, Create 9:16 cut or Create 16:9 cut renders a branded side-by-side video at 1080×1920 or 1920×1080. You can edit the label over each clip and choose whose sound it keeps: Left clip, Right clip or Both. Then use Download to save it.

How much does the Playground cost?

The Playground spends the same credits as the rest of Percify, on every self-serve plan. The price depends on the model and on the settings that move its price.

What you run	What you pay
One model	The price on the Run button. Some models charge a flat price per run. Others charge by clip length, audio length, resolution or quality, and the price updates as you change those settings.
Compare, two models	The price of each model’s run, added together. Each side is charged when it starts.
Compare, Director mode	The two model runs plus 1 to 3 credits for each director.
Marketing cut	No credits

Credits come back automatically when:

• a run fails, or a stuck run is stopped
• one side of a comparison fails (you pay only for the side that ran)
• a director fails to write its direction

Prompts and images are checked by content moderation before anything is charged. A rejected input shows “Prompt rejected by content moderation” or “Image rejected by content moderation” and costs nothing.

If your balance is too low, Percify shows how many credits the run needs and how many you have. See How Percify credits work and Not enough credits.

In Compare, if your settings cost more than the cheapest option, a reset to cheapest link appears next to the total. Use it to test prompts before paying for higher quality or longer clips.
