Mistral hero If you are building an AI system with Mistral AI LLMs and want to evaluate it, you can use the SDKs to make Openlayer part of your workflow. This integration guide shows how you can do it.

​
Evaluating Mistral AI LLMs

You can set up Openlayer tests to evaluate your Mistral AI LLMs in monitoring and development.

​
Monitoring

To use the monitoring mode, you must instrument your code to publish the requests your AI system receives to the Openlayer platform. To set it up, you must follow the steps in the code snippet below:
Python
# 1. Set the environment variables
import os

os.environ["OPENLAYER_API_KEY"] = "YOUR_OPENLAYER_API_KEY_HERE"
os.environ["OPENLAYER_INFERENCE_PIPELINE_ID"] = "YOUR_OPENLAYER_INFERENCE_PIPELINE_ID_HERE"

# 2. Import the `trace_mistral` function and wrap the Mistral client
from mistralai import Mistral
from openlayer.lib import trace_mistral

mistral_client = trace_mistral(Mistral(api_key=os.environ["MISTRAL_API_KEY"]))

# 3. From now on, every chat completion or streaming call with
# the `mistral_client` is traced by Openlayer. E.g.,
completion = mistral_client.chat.complete(
    model="mistral-large-latest",
    messages = [
        {"role": "user", "content": "What is the best French cheese?"},
    ]
)

 Once the code is instrumented, all your Mistral AI LLM calls are automatically published to Openlayer, along with metadata, such as latency, number of tokens, cost estimate, and more. If you navigate to the “Data” page of your Openlayer data source, you can see the traces for each request. Mistral trace
If the Mistral AI LLM call is just one of the steps of your AI system, you can use the code snippets above together with tracing. In this case, your Mistral LLM calls get added as a step of a larger trace. Refer to the Tracing guide for details.
After your AI system requests are continuously published and logged by Openlayer, you can create tests that run at a regular cadence on top of them. Refer to the Monitoring overview, for details on Openlayer’s monitoring mode, to the Publishing data guide, for more information on setting it up, or to the Tracing guide, to understand how to trace more complex systems.

​
Development

In development mode, Openlayer becomes a step in your CI/CD pipeline, and your tests get automatically evaluated after being triggered by some events. Openlayer tests often rely on your AI system’s outputs on a validation dataset. As discussed in the Configuring output generation guide, you have two options:
  1. either provide a way for Openlayer to run your AI system on your datasets, or
  2. before pushing, generate the model outputs yourself and push them alongside your artifacts.
For AI systems built with Mistral AI LLMs, if you are not computing your system’s outputs yourself, you must provide your API credentials. To do so, navigate to “Workspace settings” -> “Environment variables,” and click on “Add secret” to add your MISTRAL_API_KEY. If you don’t add the required Mistral API key, you’ll encounter a “Missing API key” error when Openlayer tries to run your AI system to get its outputs.
The Mistral AI client does not read the MISTRAL_API_KEY directly from the environment. Therefore, make sure to manually read it in the script you provide as the batchCommand in the openlayer.json with:
import os

api_key = os.environ["MISTRAL_API_KEY"]
client = Mistral(api_key=api_key)
