Lucy 2.5: Raising the Bar for Live AI

Summary

Decart Lucy 2.5 is a closed realtime video editor (model id lucy-2.5; lucy-latest now points here). Docs: 720p landscape/portrait over WebRTC, text prompt and/or reference image, prompt enhancement and self-anchoring on by default (re-anchor on the model’s own latent to limit drift). Marketing: live 30 FPS, physically-aware VFX, stronger temporal consistency, sub-40ms latency claims in third-party writeups. Aberman thread frames it as a world-model interaction shift, not just look. API-only; previous lucy-2.1 remains pin-able. No public weights or paper in the announcement.
