Crun
What Crun is
Crun provides a unified API for accessing more than 100 AI models for video, image, and audio generation. Video capabilities include native audio, scene reasoning, and camera control. Image endpoints support text-to-image, image-to-image, repair, upscaling, and style transfer at resolutions up to 4K. Audio generation covers voice, music, ambient sound, text-to-speech, and voice-to-voice output. Crun describes the API as OpenAI-compatible and says applications can migrate with one line of code. Pricing uses pay-as-you-go billing, volume discounts, free-tier credits, and no monthly subscriptions; pricing starts from $5. A Credits plan is listed at $1,250, paid once, billed $1250, with 12% savings and 224 Credits per dollar. Generation is asynchronous, with results retrieved by webhook or task-status polling. Media inputs must be URLs, not Base64. Generated media remains for 14 days and logs for two months before deletion.

Verdict
