# Models Metadata

GET https://app.termina.ai/api/v1/data/benchmark/metadata/models

Get metadata for benchmark model types.

Returns information about model classes (scaling and tradeoff), including:
- Model class names and descriptions
- Available model implementations
- Metrics used in each model

Reference: https://docs.termina.ai/api-reference/data/benchmark/get-models-metadata

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Servers

- `https://app.termina.ai` (Production server, default)
- `https://app.termina.dev` (Development server)
- `http://localhost:8000` (Local development server)

## Response

### 200

Successful Response

- `list of ModelsMetadataResponse`

## Types

### ModelsMetadataResponse

- `name` (string, required) — The name of the **class** of models.
- `model_description` (string, required) — A plain-english description of the class of models and what they represent.
- `available_models` (list of ModelMetadata, required) — A list of implementations and variants of this class of models.

### ModelMetadata

- `name` (string, required) — The name of the model.
- `description` (string, required) — A plain-english description of the model and what it represents.
- `columns` (list of ColumnMiniMetadata, required) — The columns used in the model.

### ColumnMiniMetadata

- `name` (string, required) — The name of the column.
- `friendly_name` (string, required) — The friendly displayable name of the column.
- `unit` (enum, required) — The unit of the category.
  - Allowed values: `string`, `percent`, `ratio`, `scalar`, `dollar`
- `scaling` (enum, required) — The scaling type of the column. Geometric indicates exponential changes are expected, while arithmetic indicates linear changes.
  - Allowed values: `geometric`, `arithmetic`
