Testing LTX-2 in the API Playground
The API Playground is a sandbox within the LTX Platform where you can test LTX-2 generation capabilities using your Platform plan's monthly credits. Experiment with different models and prompts before committing to an API integration.
What is the API Playground?
The API Playground gives you hands-on access to test LTX-2 without writing code. It's designed for experimentation: refining prompts, comparing models, and validating whether LTX-2 fits your use case before you invest in full API integration.
How credits work in the Playground
Generations in the API Playground use your Platform plan's monthly credit allowance (the same credits you use in LTX Studio). You don't need to create an API key or purchase separate API credits to use it.
If your Platform credits run out mid-month, you won't be able to generate in the playground until they reset, you upgrade your plan, or you purchase a credit top-up (if your plan allows). When you're ready to integrate LTX-2 into your products or workflows, you'd create an API key and switch to API credits.
For more on how these systems differ, see Understanding the difference between LTX Platform, the LTX-2 API, and self-hosting the open source model.
What you can test
The playground supports three task types:
- Text-to-video (t2v): Generate video from text prompts
- Image-to-video (i2v): Upload an image and extend or animate it
- Retake: Refine existing video by regenerating a portion of it
Use the playground to experiment with different models, resolutions, and output durations to find what works for your needs. The assets you generate with the playground can be downloaded, but may contain a watermark.
Using generations from the API Playground in LTX Studio projects
We recommend generating content for Studio workspace projects within Gen Space. However, if you create something with the API Playground that you want to use in the Studio workspace, you can add the asset to your project from within your project’s Video Editor.
When to move from Playground to API
Once you've tested LTX-2 capabilities and refined your approach, you're ready to transition to the API for production-scale integration. This is where you'd create an API key and begin building LTX-2 into your tools or workflows with programmatic control.
