How To Use OpenAI API For Free?


It has always been free for developers and individuals to use the OpenAI API key. With this key, you can perform various tasks, including training your dataset and creating your OpenAI-powered apps and services. OpenAI officially launched its API to the public in March 2023, which uses GPT-3.5, and also has limited access to GPT-4 for some handful of developers.

It’s a good idea to start building something powered by AI, as many daily apps and services are starting to integrate it. With those capabilities, they provide flexibility to users. You can also get access to the OpenAI API key for free, and we have step-by-step instructions along with well-thought-out things you need to know and consider while proceeding. Without further ado, let’s get into this.

What is OpenAI API?

It’s important to know what an API is. It stands for Application Programming Interface, which comes with a set of rules, protocols, and tools that allow developers to establish communication between their apps or service server and OpenAI. In simple terms, it acts like a bridge between two software programs. Once the communication has been set up, developers can use the OpenAI functionality and don’t need to build something like OpenAI, which has already invested a ton of money and resources into developing it. OpenAI API allows you to leverage OpenAI. In this article, we will learn how to get OpenAI API and how to use the OpenAI API key.

OpenAI’s GPT-4 and GPT-3 for Free – Unlimited

Reportedly, a developer has successfully exploited the OpenAI API to get access to their latest AGL Model GPT-4, which he does publish on GitHub. This gives access to OpenAI Models, including the GPT-4 and GPT 3.5, for free, and anyone can use them an infinite number of times. The company does charge for its API access, which goes from a base price of $0.03 per 1000 tokens for GPT-4 and $0.06 per 1000 Tokens. For this, the developer performed reverse engineering, and it’s worth mentioning that it wasn’t an easy job at all.
