LTX is an open video generation AI model developed by Lightricks. The company released LTX-2.5 on August 12, 2026, extending its open-model approach with multi-shot generation and HDR support. The model accepts text, image, and video inputs, generates videos with audio, and uses a Gemma 4-based custom LLM for prompt adherence plus Diffusion fidelity rendering for quality. Commercial use is permitted for companies with annual revenue under $10 million.
Earlier, on June 18, 2026, Lightricks updated LTX Trainer, the official LoRA development tool for the previous version, LTX-2.3. The update lets users create LoRA and IC-LoRA by rewriting a single configuration file, removing the need for custom code. A SKILL.md file for AI agents was also released, lowering the technical barrier for non-programmers.
Together, the stories show LTX as a free, locally-run video generation AI with a growing ecosystem of tools for customization and accessibility.
