# Muse Spark 1.2

> Muse Spark 1.2 on Clonvo: 1.05M context, $1.25 input and $4.25 output per 1M tokens.

Meta’s previous Muse Spark reasoning model for coding and agentic workflows, with vision, function calling and structured outputs.

-   Model id: `meta/muse-spark-1.2`
-   Provider: Meta
-   Released: Not published
-   Context: 1.05M tokens
-   Max output: 131K tokens

## Pricing

The provider’s list price in USD. Requests on credits are charged exactly this; each response reports its cost in usage.cost.

| Charge | Price | Unit |
| --- | --- | --- |
| Input (prompt) | $1.25 | per 1M tokens |
| Output (completion) | $4.25 | per 1M tokens |
| Cache read | $0.15 | per 1M tokens |

Data-sharing price: $0.10 input and $0.20 output per 1M tokens, for organizations that turn on Use free models in privacy settings. The provider may train on those requests; Clonvo doesn’t store them. [How it works](https://clonvo.com/docs/meta.md#data-sharing-prices).

## Quick start

Use the OpenAI SDK with Clonvo’s base URL and this model id.

```python
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.clonvo.com/v1",
    api_key=os.environ["CLONVO_API_KEY"],
)

completion = client.chat.completions.create(
    model="meta/muse-spark-1.2",
    messages=[{"role": "user", "content": "Summarise the plot of Hamlet in one sentence."}],
)
print(completion.choices[0].message.content)
```

## Data policy

Requests to this model are sent to Meta, whose API terms govern how they handle your data: [Meta data policy](https://dev.meta.ai/legal/commitments). Clonvo doesn’t store prompts or responses unless your organization turns on retention.

## Bring your own key

From Pay as you go up, a Meta key added under Provider keys is used for this model before your credits: $25,000 a month free, then 4% of list price. [How bring-your-own-key works](https://clonvo.com/docs/byok.md).
