07 Nov How Google Cloud Entertainment Biz Boss Is Explaining Fine-Tuning AI Models to Hollywood: ‘I’ve Heard People Use the Terms Incorrectly’ [Variety]

November 7, 2025 | “The thing that got us through this project is a process that sometimes gets confused, and I’ve heard people use the terms incorrectly, but there’s a process called fine-tuning of the models,” Hays told Variety. “I could say, give me an output of the Tin Man doing something without the model understanding anything about the actual Tin Man, so it comes up with some vague approximation. But that’s not good enough when you’re doing something like this. So we actually fine-tuned our models, which is a process that basically allows any IP owner to take a base model that’s been trained and has been using all the sources that people have opted into, to contribute to. So it’s a legitimate model, but it doesn’t understand the Tin Man. So what we can now do is fine-tune it on the Tin Man to say, ‘OK, you know how people move. Now we have a person that looks like this. So whenever we refer to Tin Man, please use this version of Tin Man for that.’”
Hays continued: “In that case, we had fine-tuned models for each of the main characters in the movie, and that allowed us to have a faithful reproduction of those actors, no matter where they looked and how close they were to camera, and if they turned around. Things like, what does the back of the Tin Man’s head look like? Because there’s not a lot of that in the movie, but there’s a couple of shots in there that we could tune on so that in those occasions where he had to turn his head, we knew exactly what he looked like.”
