Critterz loses its AI: OpenAI shuts down Sora and delays its Cannes debut

Published on May 25, 2026 | Translated from Spanish

The Cannes Film Festival was expecting the premiere of Critterz, an animated film that depended on Sora, OpenAI's AI video generator. However, the company suspended the service due to its high operating costs and lack of a clear monetization model. The creative team, which had already advanced part of the animation, was left without a tool and without a release date.

Technological dependence and the search for a new AI engine 🎬

The Critterz project used Sora to generate animated sequences automatically, reducing production times. With the service shutdown, developers must migrate to another AI video platform, which involves retraining models and adjusting the rendering pipeline. This technical process, combined with the lack of a confirmed alternative partner, has forced the premiere to be delayed until 2027. OpenAI clarified that it did not finance the project nor had exclusive agreements.

Cannes without a film, but with business cards 🎥

The creators of Critterz traveled to Cannes, but not to screen anything. Their goal was to find a distributor and explain to potential investors that their film exists, albeit only in the cloud of an AI that no longer works. The team's booth looks more like a tech job fair than a film festival. However, they promise that by 2027 they will have a new AI engine. Or perhaps a pencil.
