Changelog

Notable updates to RelayDance, newest first.

#2026-07

Models

• seedance-upscale-4k is now live: upscale any existing clip to native 4K, billed separately by output duration on top of the original generation cost. The console's video generation screen can trigger it automatically right after generation with no second confirmation. See /docs/super-resolution

#2026-06

Models

• gpt-image-2 added for image generation; image output is free, you pay only for input
• Seedance super-resolution launched: seedance-upscale-720p (480p to 720p) is live, with 1080p, 2k and 4k coming soon
• Grok models retired: RelayDance now serves video and image generation only

Documentation

• Docs refreshed for accuracy: every endpoint, parameter and model ID in these pages now matches the live API
• Per-site documentation: each brand documents exactly the endpoints it serves
