Crun

Crun provides a unified API for developers who want to add generated media or text to an application. Its website groups image, video, and audio models behind one service, alongside text-model access. The product is aimed at developers and businesses integrating generation into their own software.

Available generation categories

Crun offers text-to-image and image-to-image APIs, including image repair and upscaling. Its video catalog includes text-to-video, image-to-video, and reference-to-video options. Audio capabilities described on the homepage include speech generation, music, ambient sound, and voice-to-voice conversion.

The homepage names individual models and model families, with different capabilities attached to each. Features such as video duration, reference inputs, resolution, or synchronized audio should therefore be checked for the selected model. A capability listed on one model card should not be assumed to apply to the whole catalog.

Integrating an application

The setup flow starts with creating an account and an API key. A developer then selects a model, submits requests, retrieves the results, and integrates them into the application. Crun describes usage monitoring and request logs for this workflow.

The homepage includes a Python task-creation example with a model identifier and model-specific input fields. Crun provides API documentation for integration and configuration. It also advertises OpenAI compatibility, while its own example uses a task endpoint and API-key header; use the documentation for the particular endpoint you intend to call rather than assuming all media tasks share one request shape.

Credits and model costs

Crun uses a credit-based pricing system with model-specific charges. The pricing page offers credit purchase levels and explains that higher tiers can unlock lower model rates. For some video models, billing can include both input and output duration. Other entries describe token-based charges or extra image costs.

The homepage advertises a free trial for new users. Review the current credit and selected-model terms before budgeting for repeated generation. Crun's advertised savings, response times, and uptime are publisher claims; they do not establish the performance or cost of a particular application workload.
