How to use the Azure OpenAI Service REST API?
Advances in artificial intelligence, particularly with models such as OpenAI's GPT models, have opened up a range of possibilities for developers interested in integrating these technologies into their applications. Through Azure OpenAI Service, it is possible to access these models through the REST API or using the SDK available for Python and C#. Next, we will address how to employ these tools to consume GPT models effectively.
What are the elements required to consume the REST API?
To interact with GPT models using the Azure OpenAI Service REST API, three key pieces of information are essential:
- Endpoint: This is the point to which requests will be sent. It can be found in the OpenAI Studio.
- API Key: The API key allows authenticating requests to the service. Like the endpoint, it is obtained from the Azure OpenAI Studio.
- Deployed Model: It is crucial to have deployed a model in Azure to be able to query on it. In the OpenAI Studio, within the "Deployments" section, all the available models and their names are listed.
How to create a POST request with Postman?
To make a REST API request, Postman is an ideal tool thanks to its ability to parse and test APIs. Follow these basic steps:
- Create a new POST request in Postman.
- Query Azure OpenAI Studio to get the endpoint and API key.
- Configure the request body in JSON format, specifying the messages that will define the model output. For this example, a simple query will be used, "How many sides does a coin have?"
- Include query parameters, such as temperature and cap, which determine the randomness and amplitude of the responses generated by the model.
- Finally, when you send the configured request, you will receive a response in JSON format with the information and evaluation of the input and output provided by the model.
How to interact with the Python or C# SDK?
The Azure OpenAI Service SDK makes it easy for you to programmatically integrate the models into your applications. The "view code" section in the OpenAI Studio provides code samples that illustrate how to initiate queries or send prompts to a particular model.
How to configure the SDK for a successful query?
- Make sure you have an up-to-date version of the SDK compatible with your environment.
- Copy the lines of code suggested by OpenAI Studio into your Jupyter notebook or other development environment.
- Define the necessary constants:
- API base or endpoint
- Model to use
- API key, which is recommended to be handled in a safe way, typically using environment variables, although for this example it will be inserted manually.
- Execute the code to obtain a completion from the deployed model and analyze the generated response, which will include a severity assessment to categorize the content.
Conclusion
These tools will not only allow you to creatively and effectively integrate GPT models into innovative applications, but will also ensure that the generated content is properly categorized in terms of security and thematic sensitivity. Whether through Postman and the REST API or through the SDK, the invitation is to explore and leverage the potential of Azure OpenAI Service to take your projects to the next level. Go ahead, the world of AI is waiting to be discovered by you!
