Model Training
Was ist Model Training?
Model training is how an AI learns: it's shown enormous amounts of data, makes guesses, gets corrected, and gradually improves until it can perform a task reliably. The result of training is a model's weights: the stored knowledge it carries into every future interaction.

Im Vergleich
Training is the process of teaching a model: it is computationally expensive, time-consuming, and happens before the model is deployed. Inference is the process of using a trained model to generate outputs: it is much faster and cheaper, and is what happens every time you enter a prompt into an AI tool.
Stellen Sie es sich vor wie…
Model training is like a student studying for an exam over an extended period. Each practice question is a piece of training data; each wrong answer leads to a correction that adjusts the student's understanding. After enough study, the student has internalised patterns that let them answer new questions they haven't seen before. The finished, trained model is like that student at the end of revision: ready to be tested in the real world.
Profi-Tipp
When fine-tuning a model on your own images for consistent character or style generation, prioritise image diversity over quantity: twenty varied, high-quality reference images will typically produce better results than a hundred near-identical shots, as the model needs to understand the subject from multiple angles and in different lighting conditions to generalise well.
Arten und Varianten
- Model training encompasses several distinct processes.
- Pre-training involves training a model from scratch on a massive, broad dataset to give it general capabilities.
- Supervised fine-tuning involves further training on labelled examples to specialise the model for a particular task.
- Reinforcement learning from human feedback (RLHF) uses human preference signals to align model behaviour with desired outputs.
- Parameter-efficient fine-tuning methods such as LoRA train only a small subset of weights, making customisation accessible without full computational infrastructure.
- Self-supervised learning, used in many large foundation models, derives training signal from the structure of the data itself rather than explicit human labels.

- Model training in creative AI workflows most commonly appears as fine-tuning: training a base image or video generation model on a set of reference images to capture a specific character's face, a particular visual style, or a brand's aesthetic.
- Platforms such as Replicate, RunPod, and dedicated tools like Kohya SS make it possible for individual creators to run fine-tuning jobs.
- Training is also implicitly at the core of every AI tool used in production: the capabilities of Sora, Stable Diffusion, Midjourney, and similar tools are all direct products of their training data and process.
