FAQ

• What is SkyReels V4 API? SkyReels V4 API is a unified multi-modal video foundation model released by Skywork AI in February 2026. It produces video and synchronized audio in a single generation pass, supporting up to 1080p resolution, 32 FPS, and 15-second clips.
• How does the SkyReels V4 API dual-stream architecture work? It uses a dual-stream Multimodal Diffusion Transformer (MMDiT). One branch synthesizes video frames, the other generates temporally-aligned audio, and both share an MLLM-based text encoder to stay locked to the same prompt.
• Does the model generate audio natively? Yes. Audio is part of the generative stream, not a post-processing step. Dialogue, ambient sound, and music cues are produced simultaneously with video frames.
• Can SkyReels V4 edit existing video? Yes. It supports professional video inpainting, full-dimension editing (style transfer, camera-angle adjustment, subject replacement), and audio-conditioned re-generation.
• When will SkyReels V4 API be available on APIMart? Integration is in progress. It will be available on APIMart upon release, and existing APIMart keys will work immediately.
• What will it cost on APIMart? Pricing will be published upon integration. APIMart offers pay-as-you-go with no monthly minimum, typically 40-70% below list price.
• Do I need anything new to call SkyReels V4 when it launches? No. If you have an APIMart key and balance, you can use them. Simply switch the model ID in your existing call; no new SDK or authentication is required.
• What can I use while waiting? Wan 2.7, Sora 2, and Kling V2.6 are currently live on APIMart and can cover most video generation needs.
