# mirascope.core.mistral.call_response_chunk

This module contains the `MistralCallResponseChunk` class.

## <ApiType type="Class" path="core/mistral/call_response_chunk" symbolName="MistralCallResponseChunk" /> MistralCallResponseChunk

A convenience wrapper around the Mistral `ChatCompletionChunk` streamed chunks.

When calling the Mistral API using a function decorated with `mistral_call` and
`stream` set to `True`, the stream will contain `MistralResponseChunk` instances with
properties that allow for more convenient access to commonly used attributes.

Example:

```python
from mirascope.core import prompt_template
from mirascope.core.mistral import mistral_call


@mistral_call("mistral-large-latest", stream=True)
def recommend_book(genre: str) -> str:
    return f"Recommend a {genre} book"


stream = recommend_book("fantasy")  # response is an `MistralStream`
for chunk, _ in stream:
    print(chunk.content, end="", flush=True)
```
