Overview

Concrete tool for creating a GCP Vertex AI-specific Mistral client with automatic URL rewriting and Google credential authentication.

Description

The MistralGoogleCloud class creates a client for Mistral models on GCP Vertex AI. It accepts project_id, region (default "europe-west4"), and optionally an access_token. If no token is provided, it uses Google Application Default Credentials. The constructor registers a GoogleCloudBeforeRequestHook that rewrites all API request URLs to the Vertex AI rawPredict format. The client exposes .chat and .fim sub-SDKs.

Usage

Install mistralai_gcp (or mistralai[gcp]) and authenticate with gcloud auth application-default login. Then instantiate with your GCP project ID and desired region.

Usage Examples

Basic GCP Client

from mistralai_gcp import MistralGoogleCloud

# Using Application Default Credentials
client = MistralGoogleCloud(
    region="europe-west4",
    project_id="my-gcp-project",
)

response = client.chat.complete(
    model="mistral-large-latest",
    messages=[{"role": "user", "content": "Hello from GCP!"}],
)
print(response.choices[0].message.content)

With Explicit Token

from mistralai_gcp import MistralGoogleCloud

client = MistralGoogleCloud(
    region="us-central1",
    project_id="my-project",
    access_token="ya29.xxx...",  # Manual OAuth2 token
)
