Generative AI is too. Maintain your seed and you should get the same result every time.
Most of the SaaS AI tools don't expose control over their RNG, but some self-hosted ones do.
Generative AI is by definition non deterministic.
Neural networks are deterministic. In LLMs, it outputs probabilities, which are picked from via seeded RNG. Image generation tries multiple options based on different seeds, then picks the best fit as identified by a neural network and repeats. For both, if you give a specific model the same inputs, you'll get the same output.
The public-facing interfaces don't give seed control, which means they give a different output each time, but that isn't an inherent property of generative AI.
