EXCLUSIVE: Tech-driven production company Asteria has formed a strategic partnership with video generation model maker LTX with the goal of advancing cinematic AI storytelling.

The goal of the team-up is to narrow the technical gap between AI video and professional-grade production. LTX will now be the generative engine of Asteria’s AI-driven production, with the result being capable of premium-hybrid outputs.

LTX is contributing its open weights model LTX-2.3, allowing Asteria to securely train and fine-tune the model on specific IP.

The partnership came into play with 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 together, upscaling generated assets into scene-linear 16-bit HDR.

“When using AI in filmmaking, it’s incredibly important that we don’t lose the things that make our work human,” said Benjamin Michel, Co-founder, Asteria. “LTX gives the building blocks to build our own pipeline, train on our own work, and shape the model alongside other filmmakers doing the same. That kind of openness is what AI in this industry has been missing.” 

Asteria’s co-founders also include Natasha Lyonne and Bryn Mooser. The company launched in 2022.

Since LTX-2 launched on computation platform Hugging Face in January 2026, it’s been downloaded more than 10 million times, making it the industry’s most-used open weights AI model, the company says. With Asteria’s involvement, the companies are aiming to amplify the feedback from colorists, visual effects supervisors, directors and other creative stakeholders.

“There are a lot of people successfully building AI video, but few are building it with filmmakers actually in the room,” Tian Pei, LTX’s director of business development, said in a statement. “We’re seeing tools that discourage the creative process. Asteria treats AI models as part of that craft and process, not a step bolted on at the end of production. Our partnership is a natural fit as we’re all focused on enhancing filmmaking as an art form.” 

The partnership will come into play for shorts as well as feature-length productions and episodic content. The companies hope to expand the partnership into co-developed workflows, custom model training, and joint productions with the studios and brands that are already working with them.
