# Choosing a Model

> Select the right Fish Audio model for your use case and requirements

We recommend using **Fish Audio S2.1-Pro** for production projects. It improves on S2-Pro quality, latency, and throughput, and is the right choice when you need production TTFA and DPA guarantees.

Use **`s2.1-pro-free`** for testing, prototyping, development, and smaller businesses. It is the same model as S2.1-Pro at \$0, but it does not guarantee TTFA or DPA.
