LTX-2.3

Lightricks' 22B audio-video DiT — the LTX-2.3 update of the LTX-2 line, generating synchronised audio and video in one pass. Fifteen cards here carry a recipe from a 16 GB floor upward, and four of them are Apple machines: the widest Apple reach of any video model in this catalogue. Two Radeon boards run it under ROCm. Lightricks has since moved the line on to LTX-2.5, covered separately here. LTX-2 Community License.
