JoyAI-Echo - Large Scale LTX-2.3 finetune for long form (5min) coherent stories.
Researchers have developed JoyAI-Echo, a large-scale fine-tuned model based on LTX-2.3, designed for generating coherent, long-form stories up to five minutes in length. The model incorporates a Director Agent that translates unstructured user inputs into structured shot conditions, manages long-range references via an agent-level memory, and allows for local revisions without full regeneration. This approach aims to bridge the gap between explicit training data and the often less-specified nature of real user requests. AI
