decart/lucy models

lucy by Decart — AI Model Family

The lucy family represents Decart's breakthrough in real-time video transformation, enabling live editing and world simulation without the latency constraints that have historically plagued generative video. Rather than rendering video offline, lucy processes incoming video streams instantaneously—transforming backgrounds, swapping outfits, inserting objects, and altering environments at broadcast quality. This shift from post-production rendering to live-stream editing opens entirely new markets in fashion retail, content creation, gaming, and interactive media.

The lucy family currently includes lucy 14B, an image-to-video model optimized for real-time performance on consumer and enterprise hardware. Unlike traditional text-to-video generators, lucy is architected specifically for temporal consistency, low-latency inference, and complex prompt adherence—making it the first world model capable of running live without quality compromise.

lucy Capabilities and Use Cases

Image-to-Video Generation (lucy 14B)

Lucy 14B transforms static images into coherent video sequences while maintaining pixel-level physics understanding. The model can interpret natural language prompts to modify scenes in real-time, making it ideal for:

• Virtual Try-On: Fashion retailers can enable customers to see garments on themselves in motion. A prompt like "show this dress on the model walking through a bright kitchen" produces realistic fabric behavior, lighting consistency, and natural movement—all within 100 milliseconds per frame.

• Live Commerce: Streamers and influencers can dynamically insert products into their broadcasts, showcase different SKUs to different viewers, or transform their environment to match brand aesthetics without interrupting the live feed.

• Gaming and Entertainment: Content creators can swap character skins, alter game environments, or apply thematic filters responsive to real-time chat commands—all while streaming at 1080p and 30 fps.

• Personalized Content: Brands can create virtual ambassadors that appear in different locations and scenarios, building emotional connections with viewers through contextual storytelling.

The model ingests video from multiple sources—smartphone cameras, webcams, or RTMP streams—and applies transformations frame-by-frame with sub-second latency. Technical specifications include 1080p resolution, 30 fps output, and per-frame latency under 100 milliseconds, enabling seamless broadcast integration.

What Makes lucy Stand Out

Lucy's architecture differs fundamentally from competing models like Google's Veo 3 and OpenAI's Sora 3. While those models excel at offline generation, lucy is optimized for live editing with temporal consistency. Key differentiators include:

• Diffusion Pipeline for Coherence: Lucy integrates a diffusion architecture optimized for frame-to-frame consistency, eliminating the flickering and artifacts that plagued earlier video models. It outputs video continuously on a frame-by-frame basis without time constraints.

• Physics-Aware Transformation: The model understands real-world physics at the pixel level—how zippers separate cloth, how fabric folds when you sit, how lighting behaves in different environments. This happens without depth maps, green screens, or 3D meshes.

• Enhanced Prompt Adherence: Lucy interprets complex, multi-part instructions accurately. Users can request "add red, blue, and green fire-breathing dragons without affecting the original lighting," and the model executes without mistakes.

• Cost Efficiency: Optimized for NVIDIA GPUs and major cloud providers (AWS, Google Cloud), lucy achieves sustained real-time generation at approximately $3 per hour—a dramatic reduction from earlier estimates of $0.05 per second.

Lucy is ideal for fashion retailers, live-streaming platforms, e-commerce brands, content creators, and enterprises building interactive customer experiences where latency and quality are non-negotiable.
