# 1 Load packages

    library(chatAI4R)

# 2 Set the API key according to each Web API.

For example, to obtain an OpenAI API key, please register as a member on the OpenAI website (https://platform.openai.com/account/api-keys) and obtain your API key.

    #Set your key for the OpenAI API
    Sys.setenv(OPENAI_API_KEY = "Your API key")

    #Set your key for the DreamStudio API
    Sys.setenv(DreamStudio_API_KEY = "Your API key")

# 3 Simple usage

## 3.1 One-Shot Chatting

All runs using the chat4R function are One-Shot Chatting. Conversation history is not carried over to the next conversation.

    #Set your API key
    Sys.setenv(OPENAI_API_KEY = "Your API key")

    #This function use the Web API; "https://api.openai.com/v1/chat/completions"
    chat4R("What is the capital of France?")

    #This function use the Web API; "https://api.openai.com/v1/completions"
    completions4R("Hello")

## 3.2 Few-Shots/Chain-Shots Chatting

Executions using the conversation4R function will keep a history of conversations. The number of previous messages to keep in memory defaults to 2.

    #First shot
    conversation4R("Hello")

    #Second shot
    conversation4R("Hello")

# 4 Text to Image Generation (Legacy)

## 4.1 DALL·E 2 (Legacy)

Create an image generation prompt and generate an image using the DALL·E 2 model.

    # Create a prompt
    pr <- createImagePrompt(content = "A white cat. Brown cat. Fluffy. Round eyes. Round. Short hands. Sea. Photo. Facing forward.")

    # Generate an image using DALL·E 2
    img <- generateImage4R(pr)

    # Display
    Display(img)

## 4.2 Stable Diffusion (Legacy)

Create an image generation prompt and generate an image using the Stable Diffusion model.

    # Create a prompt
    pr <- createImagePrompt(content = "A white cat. Brown cat. Fluffy. Round eyes. Round. Short hands. Sea. Photo. Facing forward.")

    # Generate an image using Stable Diffusion
    img <- txt2img_StableDiffusion4R(pr)

    # Display
    Display(img)
