A class for convenience around streaming Groq LLM calls.

Example:

from mirascope.core import prompt_template
from mirascope.core.groq import groq_call


@groq_call("llama-3.1-8b-instant", stream=True)
def recommend_book(genre: str) -> str:
    return f"Recommend a {genre} book"

stream = recommend_book("fantasy")  # returns `GroqStream` instance
for chunk, _ in stream:
    print(chunk.content, end="", flush=True)

cost property 

cost: float | None

Returns the cost of the call.
