Introduction
Artificial Intelligence (AI) has revolutionized the way we interact with applications, and the integration of AI models into software development is becoming increasingly prevalent. In this article, we explore the integration of Delphi, a powerful Object Pascal-based programming language, with ChatGPT, a language model developed by OpenAI. The goal is to enable developers to create intelligent and dynamic conversational interfaces within Delphi applications.
What is ChatGPT?
ChatGPT is powered by OpenAI's advanced language model, gpt-3.5-turbo, which allows developers to build applications for various tasks such as drafting emails, writing code, answering questions, creating conversational agents, language translation, and more. This integration enables Delphi developers to leverage the capabilities of ChatGPT for natural language processing within their applications.
Installation and Initialization
To get started, you need to install the Delphi library for OpenAI, which is an unofficial implementation. You can add the library to your Delphi IDE using GetIt or by adding the root folder to the IDE library path or your project source path.
Initialization involves obtaining an API token from OpenAI and using it to create an instance of the TOpenAI
class, which serves as the entry point to the API.
uses OpenAI;
var
OpenAI: IOpenAI := TOpenAI.Create(API_TOKEN);
Once initialized, you are ready to make requests to the OpenAI API.
Models and Completions
The library provides functionality to list and describe various models available in the OpenAI API. You can retrieve information about models using the OpenAI.Model.List()
method.
var
Models := OpenAI.Model.List();
try
for var Model in Models.Data do
MemoChat.Lines.Add(Model.Id);
finally
Models.Free;
end;
For generating completions based on a prompt, you can use the OpenAI.Completion.Create
method.
var
Completions := OpenAI.Completion.Create(
procedure(Params: TCompletionParams)
begin
Params.Prompt(MemoPrompt.Text);
Params.MaxTokens(2048);
end);
try
for var Choice in Completions.Choices do
MemoChat.Lines.Add(Choice.Index.ToString + ' ' + Choice.Text);
finally
Completions.Free;
end;
Chat Conversations with ChatGPT
For chat-based language models like ChatGPT, you can simulate a conversation by using the OpenAI.Chat.Create
method.
var
Chat := OpenAI.Chat.Create(
procedure(Params: TChatParams)
begin
Params.Messages([TChatMessageBuild.Create(TMessageRole.User, Text)]);
Params.MaxTokens(1024);
end);
try
for var Choice in Chat.Choices do
MemoChat.Lines.Add(Choice.Message.Content);
finally
Chat.Free;
end;
This enables Delphi developers to create applications with dynamic and context-aware conversational interfaces.
Image Generation
The integration also allows developers to generate images from text using DALL-E, another creation from OpenAI. Here's an example:
var
Images := OpenAI.Image.Create(
procedure(Params: TImageCreateParams)
begin
Params.Prompt(MemoPrompt.Text);
Params.ResponseFormat('url');
end);
try
for var Image in Images.Data do
Image1.Bitmap.LoadFromUrl(Image.Url);
finally
Images.Free;
end;
Function Calling and Error Handling
The library supports describing functions to gpt-3.5-turbo-0613 and gpt-4-0613, allowing the model to intelligently generate JSON objects containing function arguments. It's crucial to handle errors gracefully, and the library provides exceptions for various scenarios.
try
var Images := OpenAI.Image.Create(...);
except
on E: OpenAIExceptionRateLimitError do
ShowError('OpenAI Limit Error: ' + E.Message);
on E: OpenAIException do
ShowError('OpenAI Error: ' + E.Message);
end;
Conclusion
The integration of Delphi with ChatGPT opens up exciting possibilities for developers to create applications with advanced natural language processing capabilities. By leveraging the power of ChatGPT, developers can enhance user interactions, automate tasks, and build intelligent software solutions. This integration serves as a bridge between traditional programming and the future of AI-driven applications. Explore the potential and start integrating ChatGPT into your Delphi projects today!
