# Models

> The models you can self-host, and where their requirements differ

Each model is delivered on its own: its own Helm chart, All-in-One images, versions,
and deployment guide. Your agreement grants each model separately, and **Developer →
Self Host** lists the ones your team can install. The rest of this section applies to
every model; this page covers where they differ.

## At a glance

| Model | Request header | GPU types | GPUs per deployment |
| - | - | - | - |
| S2.1 Pro | `model: s2.1-pro` | H100, H200, or B300 | Two; one in the All-in-One's Single-GPU mode, at lower throughput |
| Drama 3 | `model: drama-3` | H200 or B300 recommended | At least two or three, depending on the GPU |

## S2.1 Pro

* **The first start compiles for your GPU.** The result is cached on shared storage on
  Helm, and on the volume on the All-in-One, so later starts are quicker. Moving to a
  different GPU type compiles once more.
* **Timestamps offline.** A Helm install without internet access copies the timestamp
  model onto shared storage before turning timestamps on; the deployment runbook has the
  step.

## Drama 3

[Drama 3](https://docs.fish.audio/features/text-to-speech/drama-3.md) is a much larger model than S2.1 Pro and
needs more resources, GPUs above all; your deployment guide has the sizing. For a GPU
other than H200 or B300, check with Fish Audio before you plan around it.
