LTX-2.5: A Complete Guide to Lightricks’ Audio-Video AI Model

Overview LTX-2.5 is a DiT-based audio-video foundation model built by Lightricks that generates synchronized video and audio in a single unified pass. The model uses an asymmetric dual-stream transformer architecture with a 22B-parameter distilled transformer for video generation and separate audio encoding, coupled through bidirectional audio-video cross-attention layers with modality-aware classifier-free guidance. It accepts text […]
