OpenAI’s Generative Pre-trained Transformer (GPT) language models, such as ChatGPT, offer a glimpse into the world of artificial intelligence-generated text. However, if you’re looking for more control over the output, you’ll need to venture further. While third-party text generators exist, they have limitations and can be costly. To truly explore the capabilities of GPT, you need to get hands-on with the OpenAI API. Let’s dive into how you can do just that.

The OpenAI Playground: Your Gateway to GPT-3 and GPT-4

ChatGPT is the simplest way to access GPT models, but OpenAI provides a web app called the OpenAI Playground for a more interactive experience. It allows you to experiment directly with the API functionalities. So, sign up for an OpenAI account and head over to the OpenAI playground to get started.

If you aim to build something using the GPT API, you have a few options:

  • Write code to send requests to the GPT API.
  • Utilize Zapier to automate requests to the GPT API or ChatGPT without any coding.
  • Create a custom chatbot using Zapier’s free AI Chatbot builder.

No matter the path you choose, you’ll have access to similar controls as described below.

Unveiling the Power: Exploring API Controls


GPT’s current modes include Chat, Complete, and Edit. However, OpenAI has deprecated the latter two in favor of focusing on developing the Chat Completions API. In this article, we’ll focus on the Chat Mode and its available controls.


In Chat Mode, you can select from various GPT models. As of now, you can access models like GPT-3.5-turbo, GPT-3.5-turbo-16k, and snapshots from specific dates. GPT-4 is also accessible through the API and playground, but you’ll need an OpenAI account with a successful usage payment to enable it.

Prompt Structure

Unlike ChatGPT, the Chat Completion API and Playground offer an additional control: the System message. Alongside the User message, you can set a role for GPT using the System message. By default, it acts as a helpful assistant, but you can modify it to tailor the responses you receive.


Temperature influences the randomness of GPT’s generated text. A lower temperature yields more deterministic results, while a higher temperature adds creativity and unpredictability. Experimenting with different temperature values allows you to fine-tune the level of randomness in the output.

Maximum Length

GPT breaks down text into tokens, and the Maximum Length parameter determines the maximum number of tokens in the output. For instance, GPT-3.5 allows a maximum of 2048 tokens, equivalent to approximately 1,500 words. Keep in mind that OpenAI charges based on token usage, so generating long outputs with powerful models may incur additional costs.

Stop Sequences

Stop Sequences enable you to control the length of the generated content. By inserting a specific sequence (e.g., a period or a new line), you can prompt GPT to stop generating text accordingly. This control proves helpful when crafting structured formats like dialogues or Q&A sections.

Top P

Top P offers an alternative method to control the predictability of GPT’s output. It determines the length of the list of potential words GPT considers for the output. By adjusting the Top P value, you can influence the diversity of word choices, affecting the output’s range of possibilities.

Frequency Penalty and Presence Penalty

GPT discourages repetitive output through Frequency Penalty and Presence Penalty. With Frequency Penalty, tokens that have already appeared in the text are penalized to reduce verbatim repetition. On the other hand, Presence Penalty penalizes tokens based on their previous appearance to encourage new topics or ideas.

Unleash Your Creativity with GPT

While reading about the API controls can provide insights, nothing beats hands-on experience. Visit the OpenAI Playground and try different prompts with varying control settings. You’ll be amazed at how much the output can differ based on your selections.
