A customer from ComfyUI requested access to MistralAI's api, as it offers a nice free tier. I tried using the OpenAiChatPromptDriver to use it by setting the base_url, but received a number of errors.

import os

from dotenv import load_dotenv
from griptape.drivers import OpenAiChatPromptDriver
from griptape.structures import Agent

load_dotenv()

API_KEY = os.getenv("MISTRAL_API_KEY")

# Create an agent

agent = Agent(
    stream=True,
    prompt_driver=OpenAiChatPromptDriver(
        base_url="https://api.mistral.ai/v1",
        api_key=API_KEY,
        model="mistral-small-latest",
    ),
)

agent.run("Hello")

The response was Error code: 422:

Reverted back to enhancement since I had misinterpreted the issue. Mistral does not claim to be openai-compatible so it is expected that it does not work.
