# `ExTorch.AOTI.Server`

A GenServer that wraps a loaded AOTI (.pt2) model for concurrent serving.

Provides the same OTP fault tolerance and telemetry instrumentation as
`ExTorch.JIT.Server`, but for AOTInductor-compiled models.

## Telemetry Events

The server emits the following `:telemetry` events:

  * `[:extorch, :aoti, :load, :start | :stop]` - Model loading.
  * `[:extorch, :aoti, :forward, :start | :stop | :exception]` - Inference.

All events include `%{path: String.t()}` in metadata. Forward events also
include `%{input_count: integer()}`.

## Example

    {:ok, pid} = ExTorch.AOTI.Server.start_link(path: "model.pt2")
    [output] = ExTorch.AOTI.Server.predict(pid, [input])

## Named servers

    {:ok, _} = ExTorch.AOTI.Server.start_link(path: "model.pt2", name: FastModel)
    [output] = ExTorch.AOTI.Server.predict(FastModel, [input])

# `child_spec`

Returns a specification to start this module under a supervisor.

See `Supervisor`.

# `info`

```elixir
@spec info(GenServer.server()) :: map()
```

Get information about the loaded model.

# `predict`

```elixir
@spec predict(GenServer.server(), [ExTorch.Tensor.t()], timeout()) :: [
  ExTorch.Tensor.t()
]
```

Run inference on the model (synchronous).

## Returns
A list of output tensors.

# `start_link`

```elixir
@spec start_link(keyword()) :: GenServer.on_start()
```

Start an AOTI model server.

## Options
  - `:path` (required) - Path to the `.pt2` model package.
  - `:name` - Optional registered name.
  - `:model_name` - Model name within the package (default: `"model"`).
  - `:device_index` - CUDA device index (default: `-1` for CPU).
