Crun AI is a unified AI API platform whose core goal is to let developers access multiple top-tier AI models through a single API, covering capabilities such as video, image, audio, and text generation. The platform is aimed at developers and enterprises and emphasizes fast integration, low cost, and a developer-friendly experience.
Main capabilities
- Unified API access to over 100 mainstream AI models, covering modalities such as video, image, and audio.
- Video generation: supports multi-model generation of high-quality video, with native audio and cinematic quality, intelligent scene reasoning, precise shot control, faster rendering speeds, and lower costs; it can achieve more realistic motion generation, longer video clips, multi-image reference control, and native 1080p audio-synchronized output.
- Image generation: provides over 50 advanced models, supports text-to-image and image-to-image, image inpainting and upscaling, style transfer at up to 4K resolution, precise prompt adherence, and consistent characters and visual style.
- Audio generation: supports speech, music, and ambient sound effect generation, provides text-to-speech and speech-to-speech conversion, natural voices with multilingual support, flexible adaptation to different use cases, and low-latency fast processing.
How to use
- Register with Crun and generate a personal API Key.
- Select the required AI video, image, or audio model, and send requests through the unified API.
- Obtain results and integrate them into your product or workflow, while monitoring usage and logs in real time.
