What it does
Lucy 2.6 is Decart's video editing model, released on November 5, 2026 and now the default behind the lucy-latest alias on the Decart API platform. It edits live camera streams in realtime at 720p and pre-recorded videos as batch jobs, following a text prompt, a reference image, or both. Compared with Lucy 2.5 it follows character, garment and product references more closely, and Decart pitches it at live commerce and social streams.

- Realtime video editing. Edits a live camera stream at 720p while it runs, for character swaps, try-on, adding, replacing or removing objects, background swaps, style changes and visual effects. Official source 1 ↗
- Prompt, reference image or both. Each edit can be driven by a text description, a reference image, or both together, and the reference can be swapped mid-session without reconnecting. Official source 1 ↗ · Official source 2 ↗ · Official source 3 ↗
- Closer reference adherence. Faces, proportions and materials follow the reference more closely than Lucy 2.5, and complex garments keep their shape throughout the stream. Official source 1 ↗
- Products and props. Adds or replaces accessories, products and props on the person or in the scene, matching the reference's detail and proportions. Official source 1 ↗
- Multi-edit prompts. Several operations, such as a background replacement and a character swap, can be combined in one prompt. Official source 1 ↗
- Batch editing of recorded video. Pre-recorded MP4 clips are edited as asynchronous jobs that you submit, poll and download, with self-anchoring on by default. Official source 1 ↗ · Official source 2 ↗
