Introduction

In this article, we will be discussing the new Chat GPT API recently announced by OpenAI. This API allows developers to access the underlying model that powers Chat GPT, and build applications leveraging its capabilities. We will walk through the process of using the API to Create a simple Python web app, and explore the nuances of the Chat GPT model.

Overview of the New Chat GPT API

OpenAI has recently released the public beta of the Chat GPT API, which enables developers to integrate the powerful Chat GPT model into their applications. The model, named GPT3.5 Turbo, offers advanced natural language processing and conversation generation capabilities. This API opens up new possibilities for developers to create interactive and dynamic conversational experiences.

Updating the OpenAI Python Library

Before getting started with the Chat GPT API, it is important to ensure that the OpenAI Python library is up to date. Although the installation can typically be handled using the command pip install openai, there may be cases where pip install fails to update to the latest version. In such cases, a forced installation specifying the latest version may be required to resolve any issues.

Launching Jupiter Notebooks

To dive into the examples and code provided by OpenAI, it is recommended to launch Jupyter Notebooks. This interactive environment allows for easy experimentation and testing of the Chat GPT API. By running the provided code examples, developers can quickly gain familiarity with the API and its functionality.

Understanding the Chat GPT Model

The Chat GPT model functions similarly to the completion model, with a few key differences. When using the Chat GPT API, data is sent in a specific format to enable multi-term conversation tracking. Unlike the completion model, the Chat GPT model does not retain memory of previous questions or conversations. Each question and corresponding API call is treated as a new conversation, and Context is maintained by providing the entire conversation history with each request.

Sending Data to the API

To utilize the Chat GPT API effectively, it is crucial to understand the format of the data that needs to be sent. Rather than sending individual Prompts, developers need to format the data as a conversation history. The conversation history is a list containing dictionaries, where each dictionary represents a message in the conversation. The messages should be ordered chronologically, with the system and user messages followed by the assistant's responses.

Simulating Memory in the Chat GPT Model

Due to the lack of true memory in the Chat GPT model, it is necessary to simulate memory by providing the complete conversation history to the model. Without this simulation, the model would have no context from one question to the next. However, it is important to keep in mind that there is a token limit of 4096 for the API. If the conversation history exceeds this limit, the developer will need to truncate or remove earlier messages to avoid errors.

Limitations of the API

While the Chat GPT API offers powerful conversation generation capabilities, it does have certain limitations. Apart from the token limit, developers should be aware that the API has usage limits and associated costs. Additionally, the API is designed for single-turn tasks and may not perform optimally in complex multi-turn conversations. It is essential to understand these limitations and design applications accordingly.

Setting Parameters for Chat GPT

The Chat GPT API allows for the customization of certain parameters to control the behavior of the model. These parameters include temperature, top-p, and max tokens. Temperature affects the randomness of the model's responses, while top-p influences the diversity of generated tokens. The max tokens parameter restricts the length of the response generated by the model. Fine-tuning these parameters can help developers achieve the desired characteristics for their applications.

Building a Simple Python Web App

To demonstrate the capabilities of the Chat GPT API, we will build a simple Python web app powered by the Chat GPT model. This app will provide users with an interactive chat box where they can ask questions and receive responses generated by the model. Although the provided code is basic and not suitable for deployment as-is, it serves as a starting point for developers to explore and expand upon.

Conclusion

In conclusion, the new Chat GPT API opens up exciting possibilities for developers to create conversational applications with advanced natural language processing capabilities. By understanding the format of the conversation history and simulating memory, developers can harness the power of Chat GPT to build interactive and dynamic experiences. While the API has certain limitations, its flexibility and customization options make it a valuable tool for creating engaging conversational interfaces.
