A 22-billion-parameter open-source AI video model by Lightricks on the Diffusion Transformer (DiT) architecture, supporting text-to-video, image-to-video, audio-to-video, and video-to-video generation with native portrait output and character consistency. - Do I need a powerful GPU? No. On ltx23.app all rendering happens in the cloud. If you prefer running locally, LTX 2.3 supports ComfyUI workflows and GGUF/FP8 quantized formats for lower hardware requirements. - How does LTX 2.3 compare to other video models like WAN 2.2? On H100 GPUs, the LTX 2 series achieves roughly 18x the throughput of WAN 2.2 14B, plus native 9:16 portrait video, a reworked audio vocoder, and sharper edge detail from its rebuilt latent space. - What video specs does the model support? Videos render at up to 1080p HD in 16:9, 9:16, 1:1, and 4:3 aspect ratios with durations from 4 to 20 seconds including audio-synced output. Prompts accept up to 2,000 characters. - Is LTX 2.3 free to use? Yes — free credits for new users. The model weights are open-source and free for personal and commercial use for organizations under 10M annual revenue. Subscription plans offer volume discounts. - Can I use outputs commercially? Yes — full commercial rights with no royalty fees, no watermarks, and no additional licensing required. - Which creative styles does LTX 2.3 support? Photorealism, cinematic film, anime, cyberpunk, watercolor, oil painting, 3D rendering, time-lapse, and more, controlled through text prompts or reference images. - How do I get started? Create a free account on ltx23.app, enter a text prompt, optionally upload a reference image or audio, set parameters, then click generate.
