Mistral on GCP Python Client

Prerequisites

Before you begin, you will need to create a Google Cloud project and enable the Mistral API. To do this, follow the instructions here.

To run this locally you will also need to ensure you are authenticated with Google Cloud. You can do this by running

gcloud auth application-default login

SDK Installation

Install the extras dependencies specific to Google Cloud:

pip install mistralai[gcp]

SDK Example Usage

Create Chat Completions

This example shows how to create chat completions.

# Synchronous Example
from mistralai_gcp import MistralGCP
import os
)


res = s.chat.complete(messages=[
    {
        "content": "Who is the best French painter? Answer in one short sentence.",
        "role": "user",
    },
], model="mistral-small-latest")

if res is not None:
    # handle response
    pass

The same SDK client can also be used to make asychronous requests by importing asyncio.

# Asynchronous Example
import asyncio
from mistralai_gcp import MistralGCP
import os

async def main():
    s = MistralGCP(
        api_key=os.getenv("API_KEY", ""),
    )
    res = await s.chat.complete_async(messages=[
        {
            "content": "Who is the best French painter? Answer in one short sentence.",
            "role": "user",
        },
    ], model="mistral-small-latest")
    if res is not None:
        # handle response
        pass

asyncio.run(main())

Available Resources and Operations

chat

fim

Server-sent event streaming

Server-sent events are used to stream content from certain operations. These operations will expose the stream as Generator that can be consumed using a simple for loop. The loop will terminate when the server no longer has any events to send and closes the underlying connection.

from mistralai_gcp import MistralGCP
import os

s = MistralGCP()


res = s.chat.stream(messages=[
    {
        "content": "Who is the best French painter? Answer in one short sentence.",
        "role": "user",
    },
], model="mistral-small-latest")

if res is not None:
    for event in res:
        # handle event
        print(event)

Retries

Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.

To change the default retry strategy for a single API call, simply provide a RetryConfig object to the call:

from mistralai_gcp import MistralGCP
from mistralgcp.utils import BackoffStrategy, RetryConfig
import os

s = MistralGCP()


res = s.chat.stream(
    messages=[
        {
            "content": "Who is the best French painter? Answer in one short sentence.",
            "role": "user",
        },
    ], 
    model="mistral-small-latest",
    retries=RetryConfig(
        "backoff",
        BackoffStrategy(1, 50, 1.1, 100),
        False
    )
)

if res is not None:
    for event in res:
        # handle event
        print(event)

If you'd like to override the default retry strategy for all operations that support retries, you can use the retry_config optional parameter when initializing the SDK:

from mistralai_gcp import MistralGCP
from mistralgcp.utils import BackoffStrategy, RetryConfig
import os

s = MistralGCP(
    retry_config=RetryConfig("backoff", BackoffStrategy(1, 50, 1.1, 100), False),
)


res = s.chat.stream(
    messages=[
        {
            "content": "Who is the best French painter? Answer in one short sentence.",
            "role": "user",
        },
    ],
    model="mistral-small-latest"
)

if res is not None:
    for event in res:
        # handle event
        print(event)

Error Handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or raise an error. If Error objects are specified in your OpenAPI Spec, the SDK will raise the appropriate Error type.

Error Object Status Code Content Type
models.HTTPValidationError 422 application/json
models.SDKError 4xx-5xx /

Example

from mistralai_gcp import MistralGCP, models
import os

s = MistralGCP()

res = None
try:
    res = s.chat.complete(
        messages=[
            {
                "content": "Who is the best French painter? Answer in one short sentence.",
                "role": "user",
            },
        ],
        model="mistral-small-latest"
    )

except models.HTTPValidationError as e:
    # handle exception
    raise(e)
except models.SDKError as e:
    # handle exception
    raise(e)

if res is not None:
    # handle response
    pass

Server Selection

Select Server by Name

You can override the default server globally by passing a server name to the server: str optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the names associated with the available servers:

Name Server Variables
prod https://api.mistral.ai None

Example

from mistralai_gcp import MistralGCP
import os

s = MistralGCP(server="prod")


res = s.chat.stream(
    messages=[
        {
            "content": "Who is the best French painter? Answer in one short sentence.",
            "role": "user",
        },
    ], 
    model="mistral-small-latest"
)

if res is not None:
    for event in res:
        # handle event
        print(event)

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the server_url: str optional parameter when initializing the SDK client instance. For example:

from mistralai_gcp import MistralGCP
import os

s = MistralGCP(
    server_url="https://api.mistral.ai",
)


res = s.chat.stream(
    messages=[
        {
            "content": "Who is the best French painter? Answer in one short sentence.",
            "role": "user",
        },
    ], 
    model="mistral-small-latest"
)

if res is not None:
    for event in res:
        # handle event
        print(event)

Custom HTTP Client

The Python SDK makes API calls using the httpx HTTP library. In order to provide a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration, you can initialize the SDK client with your own HTTP client instance. Depending on whether you are using the sync or async version of the SDK, you can pass an instance of HttpClient or AsyncHttpClient respectively, which are Protocol's ensuring that the client has the necessary methods to make API calls. This allows you to wrap the client with your own custom logic, such as adding custom headers, logging, or error handling, or you can just pass an instance of httpx.Client or httpx.AsyncClient directly.

For example, you could specify a header for every request that this sdk makes as follows:

from mistralai_gcp import MistralGCP
import httpx

http_client = httpx.Client(headers={"x-custom-header": "someValue"})
s = MistralGCP(client=http_client)

or you could wrap the client with your own custom logic:

from mistralai_gcp import MistralGCP
from mistralai_gcp.httpclient import AsyncHttpClient
import httpx

class CustomClient(AsyncHttpClient):
    client: AsyncHttpClient

    def __init__(self, client: AsyncHttpClient):
        self.client = client

    async def send(
        self,
        request: httpx.Request,
        *,
        stream: bool = False,
        auth: Union[
            httpx._types.AuthTypes, httpx._client.UseClientDefault, None
        ] = httpx.USE_CLIENT_DEFAULT,
        follow_redirects: Union[
            bool, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
    ) -> httpx.Response:
        request.headers["Client-Level-Header"] = "added by client"

        return await self.client.send(
            request, stream=stream, auth=auth, follow_redirects=follow_redirects
        )

    def build_request(
        self,
        method: str,
        url: httpx._types.URLTypes,
        *,
        content: Optional[httpx._types.RequestContent] = None,
        data: Optional[httpx._types.RequestData] = None,
        files: Optional[httpx._types.RequestFiles] = None,
        json: Optional[Any] = None,
        params: Optional[httpx._types.QueryParamTypes] = None,
        headers: Optional[httpx._types.HeaderTypes] = None,
        cookies: Optional[httpx._types.CookieTypes] = None,
        timeout: Union[
            httpx._types.TimeoutTypes, httpx._client.UseClientDefault
        ] = httpx.USE_CLIENT_DEFAULT,
        extensions: Optional[httpx._types.RequestExtensions] = None,
    ) -> httpx.Request:
        return self.client.build_request(
            method,
            url,
            content=content,
            data=data,
            files=files,
            json=json,
            params=params,
            headers=headers,
            cookies=cookies,
            timeout=timeout,
            extensions=extensions,
        )

s = MistralGCP(async_client=CustomClient(httpx.AsyncClient()))

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name Type Scheme
api_key http HTTP Bearer

To authenticate with the API the api_key parameter must be set when initializing the SDK client instance. For example:

from mistralai_gcp import MistralGCP
import os

s = MistralGCP()


res = s.chat.stream(
    messages=[
        {
            "content": "Who is the best French painter? Answer in one short sentence.",
            "role": "user",
        },
    ], 
    model="mistral-small-latest"
)

if res is not None:
    for event in res:
        # handle event
        print(event)
