# Choosing a model

There's no single best model - each has strengths:

* **Prompt adherence** - how literally the model follows instructions
* **Identity consistency** - how well it preserves faces/characters from references
* **Lip-sync and language support** - varies a lot between video models
* **Speed vs. quality** - "fast" model variants trade fidelity for turnaround

We regularly add new models and update existing ones. When something matters (a client deliverable, a character's identity), test 2–3 models with the same prompt and compare.
