Exclusive: Technology-driven production company Asteria has entered into a strategic partnership with video generation model maker LTX with the aim of advancing AI storytelling in film.
The goal of this team-up is to close the technological gap between AI video and professional-level production. LTX will now become the generation engine for Asteria’s AI-driven production, thereby enabling premium hybrid output.
Deadline details
LTX offers an open weight model LTX-2.3 that allows Asteria to safely train and fine-tune models on specific IP.
This partnership was realized in a short animated film Chikaboom!which premiered at this month’s Tribeca Festival. Asteria used LTX’s HDR IC-LoRA to integrate hand-drawn 2D, CG, and AI animation and upscale the resulting assets to scene-linear 16-bit HDR.
“When using AI in filmmaking, it’s critical that we don’t lose what makes our work human,” said Benjamin Michel, co-founder of Asteria. “LTX provides the building blocks to build your own pipeline, train on your own work, and form models with other filmmakers who are doing the same. This kind of openness is what is missing in AI in this industry.”
Asteria co-founders also include Natasha Lyonne and Bryn Mooser. The company was launched in 2022.
Since LTX-2 was released on the computing platform Hugging Face in January 2026, it has been downloaded more than 10 million times, making it the most used open weight AI model in the industry, the company said. With Asteria’s involvement, the companies aim to enhance feedback from colorists, visual effects supervisors, directors, and other creative stakeholders.
““There are many people who are successfully building AI videos, but very few are actually building AI videos with filmmakers in the field,” Tian Pei, director of business development at LTX, said in a statement. “Tools are emerging that impede the creative process. We treat models as part of the craft and process, rather than an added step at the end of production. Our partnership is a natural fit as we are all focused on strengthening filmmaking as an art form.”
This partnership applies not only to short films, but also to long-form productions and episodic content. The companies hope to expand their partnership into co-development workflows, custom model training, and co-creation with studios and brands they already work with.
