Step 8 - Test provider

After configuring Mistral as a provider, you should test the connection to verify it's working correctly. This video demonstrates how to use the gateway's testing interface to send a sample prompt to Mistral and confirm that your configuration is functioning properly.

To verify that your Mistral provider connection is working correctly, navigate to the Testing tool from the left sidebar in Ozeki AI Gateway. Select "Mistral" as the provider and choose a model such as "devstral-2512". Enter a test prompt like "Where is Budapest?" and click Send to submit the request to Mistral's API (Figure 10).

After submitting the test prompt, Mistral's response is displayed on the page. A successful response confirms that the complete communication chain is working: the gateway connected to Mistral, transmitted your prompt, and received a valid response from the AI model (Figure 11).
