# Models

> Available models, capabilities, and intelligent routing.

## Public model

AtlasFlux exposes a single model identifier:

```
atlasflux/nenas-flash
```

You do not need to specify model names. AtlasFlux automatically routes each request to the best model.

## Model capabilities

| Capability               | Supported        |
| ------------------------ | ---------------- |
| Text generation          | Yes              |
| Vision (images)          | Yes              |
| Reasoning                | Yes              |
| Web search               | Yes              |
| Streaming                | Yes              |
| Tool calling             | Yes              |
| Structured output (JSON) | Yes              |
| Context window           | 1,000,000 tokens |
| Max output               | 32,000 tokens    |

## Intelligent routing

When you send a request, AtlasFlux evaluates:

1. **Task type** — Code, analysis, creative writing, etc.
2. **Complexity** — Simple questions vs. multi-step reasoning
3. **Input features** — Images, tools, structured output requirements
4. **Reasoning effort** — Whether reasoning mode is requested

Based on this, the router selects the optimal model from its internal model pool.

## Routing categories

| Category     | Description                                      |
| ------------ | ------------------------------------------------ |
| `general`    | Standard text tasks, Q\&A, summarization         |
| `multimodal` | Tasks involving images or audio                  |
| `reasoning`  | Complex analysis, math, multi-step problems      |
| `structured` | JSON schema, function calling, structured output |
| `classifier` | Simple classification and categorization tasks   |

## Model response

The response includes routing metadata:

```json theme={null}
{
  "routing": {
    "category": "general",
    "upstream_model": "atlasflux/nenas-flash",
    "reasoning": "Selected for general text generation"
  }
}
```

## Pricing

All models use the same AtlasFlux pricing:

| Token Type | Rate per 1M tokens |
| ---------- | ------------------ |
| Input      | RM 5.00            |
| Output     | RM 25.00           |
| Reasoning  | RM 25.00           |
