Tech-driven production company Asteria has formed a strategic partnership with video generation model maker LTX to advance cinematic AI storytelling, aiming 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, contributing its open weights model LTX-2.3, which allows Asteria to securely train and fine-tune the model on specific IP. The partnership debuted with the short animated film *ChikaBOOM!*, which premiered at this month’s Tribeca Festival, where 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. Asteria’s co-founders include Benjamin Michel, Natasha Lyonne, and Bryn Mooser; the company launched in 2024. Since LTX-2 launched on Hugging Face in January 2026, it has been downloaded more than 10 million times, making it the industry’s most-used open weights AI model, according to the company. The partnership will apply to shorts, feature-length productions, and episodic content, with plans to expand into co-developed workflows, custom model training, and joint productions with studios and brands.
