# GPT 6 Luna

> Efficient GPT 6 model for focused, high-volume tasks.

Efficient GPT 6 model for focused, high-volume tasks.

## Model Information

| Field        | Description        |
| ------------ | ------------------ |
| `model`      | gpt-6-luna         |
| `context`    | 1,050,000 tokens   |
| `max output` | 128K tokens        |
| `endpoint`   | POST /v1/responses |

Context and output sizes describe the model specification. Effective request limits, availability, and billing depend on the MixRoute route.

## Capabilities and Usage

* Accepts text and images and produces text.
* reasoning.effort supports none, low, medium, high, xhigh, and max. Higher effort trades latency and output-token usage for more reasoning.

## Request Example

Set `MIXROUTE_API_KEY` before making the request.

```bash theme={null}
curl --request POST "https://api.mixroute.ai/v1/responses" \

  --header "Content-Type: application/json" \
  --data '{
  "model": "gpt-6-luna",
  "input": "Explain the tradeoffs of database indexes.",
  "reasoning": {
    "effort": "low"
  },
  "max_output_tokens": 1024,
  "store": false
}'
```
