Setting up your OpenAI Playground environment

The OpenAI Playground is an interactive web-based interface designed to allow users to experiment with OpenAI’s language models, including ChatGPT. It’s a place where you can learn about the capabilities of these models by entering prompts and seeing the responses generated in real time. This platform acts as a sandbox where developers, researchers, and curious individuals alike can experiment, learn, and even prototype their ideas.

In the Playground, you have the freedom to engage in a wide range of activities. You can test out different versions of the AI models, experimenting with various prompts to see how the model responds, and you can play around with different parameters to influence the responses generated. It provides a real-time glimpse into how these powerful AI models think, react, and create based on your input.

Getting ready

Before you start, you need to create an OpenAI Platform account.

Navigate to https://platform.openai.com/ and sign in to your OpenAI account. If you do not have an account, you can sign up for free with an email address. Alternatively, you can log in to OpenAI with a valid Google, Microsoft, or Apple account. Follow the instructions to complete the creation of your account. You may need to verify your identity with a valid phone number.

How to do it…

  1. After you have successfully logged in, navigate to Profile in the top right-hand menu, select Personal, and then select Usage from the left-hand side menu. Alternatively, you can navigate to https://platform.openai.com/account/usage after logging in. This page shows the usage of your API, but more importantly, it shows you how many credits you have available.
  2. Normally, OpenAI provides you a $5 credit with a new account, which you should be able to see under the Free Trial Usage section of the page. If you do have credits, proceed to step 4. If, however, you do not have any credits, you will need to upgrade and set up a paid account.
  3. You need not set up a paid account if you have received free credits. If you run out of free credits, however, here is how you can set up a paid account: select Billing from the left-hand side menu and then select Overview. Then, select the Set up paid account button. You will be prompted to enter your payment details and set a dollar threshold, which can be set to any level of spend that you are comfortable with. Note that the amount of credits required to collectively execute every single recipe contained in this book is not likely to exceed $5.
  4. After you have created an OpenAI Platform account, you should be able to access the Playground by selecting Playground from the top menu bar, or by navigating to https://platform.openai.com/playground.

How it works…

The OpenAI Playground interface is, in my experience, clean, intuitive, and designed to provide users easy access to OpenAI’s powerful language models. The Playground is an excellent place to learn how the models perform under different settings, allowing you to experiment with parameters such as temperature and max tokens, which influence the randomness and length of the outputs respectively. The changes you make are instantly reflected in the model’s responses, offering immediate feedback.

As shown in Figure 1.1, the Playground consists of three sections: the System Message, the Chat Log, and the Parameters. You will learn more about these three features in the Running a completion request in the OpenAI Playground recipe.

Now, your Playground is set up and ready to be used. You can use it to run completion requests and see how varying your prompts and parameters affect the response from OpenAI.
