OpenAI API Key and Models Overview

In this section, the speaker discusses the importance of keeping the OpenAI API key safe and provides an overview of the models available.

OpenAI API Key Security

It is crucial to keep the API key safe to prevent unauthorized access and potential misuse.

If a credit card is attached to under billing, there is a risk of incurring excessive charges on credit card bills.

Available Models

The OpenAI API is powered by a diverse set of models with different capabilities and price points.

The newest model available at the time of writing is GPT-4.

GPT-4 uses a set of models that improve on GPT 3.5 and can understand and generate natural language or code.

DALL-E is an AI system that can create realistic images and art from a description in natural language.

WISPR is a general-purpose speech recognition model capable of multilingual speech recognition, speech translation, and language identification.

Text Completion with OpenAI API

This section focuses on text completion using the OpenAI API.

Text Completion Functionality

Text completion allows for generating or manipulating text by completing sentences or prompts.

The API can complete sentences based on given prompts or generate completions from scratch.

The output may vary even if the prompt remains unchanged due to non-deterministic behavior by default.

Making Requests for Text Completion

A POST request should be used for text completion with the OpenAI API.

Required parameters include specifying the model to use (e.g., "text-davinci-003").

Request Body Parameters:

Prompt: A string or array passed to generate completions for. Example: "Hello, how are you today?"

Suffix (optional): Strings that come after the completion of inserted text.

Max Tokens (optional): An integer representing the maximum number of tokens to generate in the completion.

Temperature (optional): A number from 0 to 2, where higher values make the output more random and lower values make it more focused and deterministic.

Top P (alternative to Temperature): Uses nuclear sampling instead of temperature for token selection.

Tokenization

Tokens are used by models to process text and represent common sequences of characters found in text.

The API provides information on the number of tokens used in a given piece of text.

One token generally corresponds to roughly four characters or three-quarters of a word in common English text.

The total token count, including prompt and max tokens, should not exceed the model's context length (e.g., 2048 tokens).

Generating Multiple Completions

This section explains how to generate multiple completions using the OpenAI API.

Setting Number of Completions

The "n" parameter allows specifying how many completions to generate for each prompt by passing an integer value.

Please refer to the full transcript for complete details and additional sections not covered here.

Setting up the Project

In this section, the speaker explains how to set up a simple project for making API requests using JavaScript.

Creating the HTML and JS Files

Create an index HTML file with boilerplate code.

Link the app.js file using a script tag.

Writing the API Request in app.js

Define an async function called fetchData.

Use the await keyword to wait for the response from the fetch API.

Save the response to a constant variable called response.

Set the URL for the request, which is provided in the documentation.

Pass through options including method (POST), headers (including API key), and content type (JSON).

Wrap the body of options in JSON.stringify and include necessary parameters like model, prompt, and max tokens.

Await and save the response as data.

Console log data to see the response.

Making POST Requests with cURL Command

In this section, the speaker demonstrates how to make POST requests using cURL command instead of JavaScript.

Using cURL Command

Open terminal or command prompt.

Copy and paste the provided cURL command that includes endpoint, content type, authorization header with API key, and other necessary parameters.

Replace API key placeholder with your own API key.

Execute the command to make a request and receive a response.

Conclusion

The speaker concludes by summarizing what was covered in setting up a project for making API requests using JavaScript and also demonstrates making requests using cURL command.

Writing Effective Prompts

In this section, the speaker discusses three guidelines for creating effective prompts when working with OpenAI models.

Show and Tell

Make it clear what you want from the model by providing instructions or examples.

Explicitly state your desired outcome, such as ranking items in alphabetical order or classifying text by sentiment.

Providing Quality Data

Ensure that you have enough examples to train the model for tasks like building a classifier or pattern recognition.

Proofread your examples to avoid unintentional influence on the model's response.

Check Your Settings

Adjust the temperature and top B settings based on your desired response.

Lower these settings for questions with one correct answer and higher for more diverse responses.

Introduction to Chat Completions

This section introduces chat completions and explains how they can be used with OpenAI models through the OpenAI chat API.

What is Chat Completions?

Chat completions involve having a conversation with an OpenAI model using the GPT 3.5 turbo or GPT for model.

The OpenAI chat API allows various applications such as writing code, suggesting text, creating AI chat agents, translating languages, and more.

Advantages of Using Chat Completions

Chat completions provide a more interactive experience compared to text completions.

The GPT 3.5 turbo performs similarly to text DaVinci 003 but at a lower cost per token.

Making Requests to OpenAI Chat API

This section explains how to make requests to the OpenAI chat API using JavaScript fetch API.

Endpoint and Options

Use the endpoint "/chat/completions" to make a POST request to the OpenAI chat API.

Include your API token and specify the model (GPT 3.5 turbo or GPT) in the request.

Messages Format

The "messages" field in the request takes an array of objects in a specific chat format.

Each object should have a role (e.g., "system", "user", "assistant") and content for the prompt.

Fetching Data with JavaScript

Use the fetch API to make a POST request to the OpenAI chat API.

Pass the endpoint and options (including authorization header with your API key) as parameters.

Writing JavaScript Code for Fetch Request

This section demonstrates writing JavaScript code to make a fetch request to the OpenAI chat API.

Fetch Data Function

Create a function called "fetchData" that uses async/await and fetch API.

Pass the endpoint and options (method, headers with authorization) as parameters.

Endpoint and Options

Set the endpoint as "/chat/completions".

Specify the method as "POST" and include headers with authorization using your API key.

Conclusion

The speaker concludes by summarizing what has been covered so far regarding effective prompts, chat completions, making requests to OpenAI chat API, and writing JavaScript code for fetch requests.

Working with the API

In this section, the speaker explains how to work with the API and pass necessary parameters.

Passing Parameters to the API

To work with the API, we need to pass a body object wrapped in JSON.

The required parameters include:

Model: Specify the model to use (e.g., GPT).

Messages: Pass an array of message objects, each containing a role (user or assistant) and content.

Example Message Object

Each message object represents a chat message.

It consists of a role (user or assistant) and content.

Multiple messages can be passed for a conversation.

Retrieving Response from the API

After making the API call, we wait for the response and save it as data.

We can then access the JSON data using data.json().

The response contains an array of messages from the assistant.

Using Call Command

The speaker demonstrates how to use the call command to interact with ChatGPT.

Making a Call Command

The call command is another way to interact with ChatGPT.

We provide the URL and replace placeholders like API key and model name.

We can directly execute commands in our browser's console.

Project Directions

The speaker discusses two project directions using ChatGPT: building a simple JavaScript project and building a React project.

Simple JavaScript Project

This project is suitable for beginners who want to learn how to use ChatGPT in JavaScript.

It involves creating a front-end application using HTML, CSS, and JavaScript.

Fetch API is used to communicate with ChatGPT API.

However, it's important not to publish this code publicly as it may expose the API key.

React Project

The React project is an extension of the simple JavaScript project.

It allows for easier back-end development and additional features.

The prompts can be stored in a chat history, and clicking on them retrieves the entire chat history.

Users can add more text to the conversation and switch between different chats.

Making a Request to the DALL-E Model

In this section, the speaker explains how to make a request to the DALL-E model using API references. The process involves making a POST request to a specific URL and passing through some options, including the method (post), headers (authorization with API key), content type (JSON), and body (an object with prompt, number of images, and size).

Making the POST Request

To make a request to the DALL-E model, use the fetch API keyword.

Define the method as post in the options for the fetch request.

Pass through headers, including authorization with backticks and API key.

Define content type as JSON.

Set up the body as an object containing prompt, number of images (n), and size.

Handling User Input

Retrieve user input from an input element using document.querySelector('input').

Get the value of the input element when clicked on.

Include user input in the body object along with other options.

Fetching Data and Parsing JSON Response

Use await keyword before fetch function call to wait for response.

Testing getImages Function

Go back to your project and open up the console log.

Make sure to obtain an API key, which can be created under "API keys" in your project settings.

Use this API key when making requests from your frontend application.

The transcript provided does not contain enough information beyond this point.

Creating the .env File

In this section, the speaker explains how to create a .env file and define an API key in it. This allows for easy access to the API key using process.env in the code.

Creating the .env File

Create a new file called .env.

Define the API key by adding API_KEY= followed by the actual API key string. No quotation marks are needed as the string is implied.

By doing this, you can now use process.env to access and retrieve the API key from the .env file.

Communicating with the API

The speaker demonstrates how to communicate with an API by making a request using an example prompt.

Making a Request

Click on "Generate" to send a request to the API.

Pass through a prompt, such as "cute baby otter".

The response from the API will be displayed in the terminal.

To access specific data within the response, use dot notation. For example, data.data will give you an array of URLs.

If necessary, click "Generate" again to see updated results.

Displaying Images from Response

After receiving images from the API response, this section focuses on displaying those images on the front end using React's useState hook.

Using useState Hook and Setting Images State

Import useState from React.

Declare a state variable called images using useState, initializing it with null.

Once you receive data from the response (data.data), set that data as your new value for images.

Mapping Images onto HTML Elements

Within the image section, map each image from the images state.

Retrieve the index of each image (which will be used as a key) and the actual image itself.

Create an <img> element for each image, setting its source to image.url.

Provide alternative text for accessibility purposes, such as "generated image of [prompt]".

Handling Input Value

This section covers handling input value changes and displaying it on the front end.

Setting and Displaying Input Value

Import useState from React.

Declare a state variable called value using useState, initializing it with null.

Use the onChange event to update the value when the input changes. Set it to e.target.value.

This tutorial provides a basic understanding of how to use OpenAI API for uploading files and processing them.

Advanced features like image cropping are not covered in this tutorial.

Building a Modal Component

In this section, the speaker discusses the process of building a modal component for displaying image previews.

Creating the Modal Component

A new directory called "components" is created in the source directory.

Inside the "components" directory, a new file named "modal.js" is created to build the modal component.

The modal component is defined as a functional component using JSX syntax.

The modal has a class name of "modal".

State hooks are imported from React to handle error messages and control the open/close state of the modal.

The initial value for error state is set to null using useState hook.

Another state variable, "modalOpen", is initialized as false using useState hook. This variable controls whether the modal is open or closed.

Implementing Modal Functionality

The modal component is imported into another file for usage.

An overlay div element is created to overlay on top of other content when the modal is open. It has a class name of "overlay".

The overlay div element should only be displayed if modalOpen state variable is true.

A close button (represented by an 'x') inside a div element is added to allow closing of the modal. Clicking on this button triggers a function called closeModal.

closeModal function sets modalOpen state variable to false using setModalOpen(false).

Additionally, it sets another state variable called selectedImage to null using setSelectedImage(null).

Displaying Image Preview

A div with class name "image-container" is added after the close button div. This will hold the image preview.

The image container should only be displayed if there's a selected image available (selectedImage !== null).

An <img> element is used to display the selected image. The source of the image is set to selectedImage and an alternative text of "uploaded image" is provided.

To correctly pass the selected image data to the modal component, it needs to be passed as a prop from another component.

The selectedImage prop is destructured in the modal component so that it can be used within the JSX.

Adding Generate Button

After the image container div, a button with text "generate" is added.

The functionality for generating something from the selected image is not discussed in this section.

Styling and Finalizing Modal Component

In this section, the speaker continues working on styling and finalizing the modal component.

Styling Overlay and Modal

CSS classes are applied to style both overlay and modal components.

Specific styles for positioning, background color, opacity, etc., are added to achieve desired visual effects.

Closing Modal Functionality

The closeModal function is defined inside the modal component.

When clicking on the close button ('x'), closeModal function sets modalOpen state variable to false using setModalOpen(false).

Additionally, it sets another state variable called selectedImage to null using setSelectedImage(null).

Displaying Selected Image Preview

An <img> element inside the image container div displays the selected image preview.

To correctly pass and display the selected image data in URL format, it needs to be passed as a prop from another component.

The selectedImage prop is destructured in the modal component so that it can be used within JSX.

However, there seems to be an issue with passing and displaying URL correctly. Further debugging may be required.

Adding Generate Button

A button with text "generate" is added after the image container div.

The functionality for generating something from the selected image is not discussed in this section.

Reviewing Modal Component

In this section, the speaker reviews the progress made on the modal component and identifies an issue with displaying the selected image.

Debugging Selected Image Display

The speaker logs the selectedImage prop to console to inspect its structure.

It is observed that selectedImage appears as an object instead of a URL.

To display the selected image correctly, it needs to be passed through a URL object using URL.createObjectURL(selectedImage).

Finalizing Modal Component

The progress made on building and styling the modal component is reviewed.

The modal component can now display an overlay, close button, and selected image preview.

Further improvements or additions to functionality are not discussed in this section.

Styling the Modal

In this section, the speaker focuses on styling the modal component. They start by setting the width and height of the modal and ensuring that scrolling is disabled.

In this section, the speaker applies styling to various elements using CSS.

Applying Styling with CSS

The font family for all elements in the project is set to Verdana, with fallback options of Helvetica and sans-serif.

The text color is set to a very dark gray (RGB value).

Paragraph elements and input fields have a font size of 16 pixels.

Default margin and padding are removed from the body element.

The app container is centered using flexbox properties (justify-content: center, align-items: center).

The background color of the app container is set to RGB(250, 250, 250).

The app container has a height of 100 viewport height (vh) and width of 80 viewport width (vw).

The app container has a white background color (RGB value).

The app container has a slight border radius of 10 pixels.

A box shadow is added to the app container with black color and transparency, and an offset of 0px on the x-axis, 1px on the y-axis, and a blur radius of 4 pixels.

Starting Backend

In this section, the speaker explains how to start the backend for the project using TypeScript.

Starting Backend

To start the backend in a TypeScript project with type modules, use ts-node and ESM.

Add type: module in the index TS file to enable importing modules.

Install required packages (ts-node, cors, express) using npm.

Create an index TS file for the backend.

Use npm run start:frontend to start the frontend at localhost port 3000.

Styling Code Display

Styling Code Display

The code display element is selected for styling.

The width of the code display is set.

Adding Buttons and Code Display

In this section, the speaker discusses adding buttons and a code display to the webpage. They explain how to create a div element to hold the buttons and style them using CSS. The speaker also demonstrates how to add separate class names for each button and change their background colors.

Adding Buttons

Create a div element with the class name "buttons" to hold the buttons.

Add three buttons inside the div, giving them all the class name "button".

Assign separate class names for each button, such as "first", "middle", and "last".

Style the buttons using CSS properties like width, border radius, margin, and background color.

Styling Code Display

Create another div after the buttons div to hold the code output.

Give this div a class name of "code output" and style it accordingly.

Set its width to match that of the code display.

Add overflow-y property with scroll value to enable vertical scrolling if needed.

Styling Messages Display

In this section, the speaker focuses on styling the messages display on the webpage. They explain how to create individual message blocks with rounded edges and arrange them in a flex container. The speaker also demonstrates how to space out each message block and add scroll functionality if there are too many messages.

Styling Message Blocks

Each message block should be a square shape with rounded edges.

Use CSS properties like border radius, box-sizing, background color, padding, and margin to style each message block.

Arrange message blocks in a flex container using display:flex property.

Ensure that everything inside each message block appears from left to right.

Scroll Functionality

If there are more messages than can fit in the display, enable vertical scrolling.

Add overflow-y property with scroll value to the messages display div.

Always Display Scrollbar

In this section, the speaker explains how to ensure that the scrollbar is always visible in the messages display. They provide a code snippet to achieve this functionality.

Always Display Scrollbar

To make the scrollbar always visible, add a CSS code snippet to the messages display div.

This code snippet ensures that even if there are not enough messages to trigger scrolling, the scrollbar will still be present.

The transcript provided does not include any additional information or content beyond what is summarized above.

Styling the Input Element

In this section, the speaker focuses on styling the input element of the project.

Styling the Input Element

The input element is padded with zero pixels from the top and bottom, and seven pixels from the left and right. This is done to separate it from other elements in the project.

The input element is given a border using box-sizing: border-box property. It has a solid black color with an opacity of 0.16 and a width of one pixel. It is also padded with 16 pixels and has a margin of 2%.

To center the input element within the app, flexbox is used on the app container. The flex direction is set to column to stack all elements vertically.

The edges of the input element are rounded off with a border radius of five pixels.

Conclusion

The input element in the project is styled by adding padding, borders, margins, and rounding off its edges using CSS properties.

[t=4:51:45s] Setting up the Server

In this section, the speaker discusses setting up the server and creating a route to an endpoint.

Listening for Changes on the Server

The speaker sets the port to 8000 and creates a callback function to log that the server is running on that port.

Creating an Endpoint

The speaker creates a POST request endpoint at "localhost:8004/completions".

The endpoint is an async function that takes in a request and response.

Error handling is implemented using try-catch, with any errors being logged to the console.

Using OpenAI's Chat Completion

The speaker uses OpenAI's create chat completion function by passing in the desired model (GPT) and messages as part of the chat. Messages are represented as an array of objects, with each object containing a user role and message content.

A SQL request is appended to each message before sending it to OpenAI.

Handling Response from OpenAI

The completion response is received and processed by extracting data from the choices array. The first choice's message is retrieved as the output from AI.

[t=4:56:01s] Fetching Data from Frontend

This section focuses on fetching data from the frontend using JavaScript's fetch API.

Triggering Query on Button Click

An event listener is added to trigger a query when a button is clicked.

A function named "get query" is defined to handle the query. Error handling is implemented using try-catch.

Fetching Data from Backend

The fetch API is used to send a POST request to the backend endpoint created earlier. The request body includes a JSON stringified object with a message property containing the desired query. Headers are also included for working with JSON data.

The response from the backend is received and converted to JSON format. The resulting data is logged to the console for inspection.

Setting up the Server

In this section, the speaker discusses running the server on port 8000 and clearing any previous data.

Running the Server

The server is now running on port 8000.

The speaker clears any previous data to start fresh.

Receiving and Displaying Messages

This section focuses on receiving and displaying messages from the assistant.

Receiving Messages

After clicking on a message, the speaker waits for the response to come back.

The received message contains information about its role (assistant) and content (SQL request).

The speaker plans to display this message in the app TSX file.

Using State to Save Chat Data

The speaker imports useState from React to save chat data in the state of the app.

A chat variable is created using const chat, setChat = useState([]) with an initial value of an empty array.

An interface called chatData is defined with properties for role (string) and content (string).

The chat state will only accept objects that match this interface.

Updating Chat State

When receiving new chat data, the speaker wants to add it to the existing array without overriding it.

To achieve this, they use a previous state variable (oldChat) obtained through destructuring assignment.

The new chat data is added to oldChat, preserving all previous messages.

Handling User Input

This section covers handling user input and updating its value in real-time.

Handling User Input Value

A new state variable called value is created using const value, setValue = useState('') with an initial value of an empty string.

The value state will always be a string.

The speaker uses the value variable to override the hard-coded input value.

Updating User Input Value

The speaker uses the onChange event to update the value state based on user input.

The event object is passed as an argument, and setValue is used to update the value accordingly.

Creating User Message Object

A new object called userMessage is created to represent the user's message.

It has properties for role (hard-coded as "user") and content (the value of what was typed in the input field).

This object is then added to the chat array.

Filtering and Displaying Messages

This section focuses on filtering and displaying messages based on their role.

Filtering User Messages

The chat array is filtered to separate user messages from other messages.

Only messages with a role equal to "user" are included in the filtered array.

Passing Filtered Messages

The filtered user messages are passed as props to a component called "MessageDisplay".

Summary and Conclusion

In this final section, the speaker summarizes what has been covered so far.

Summary of Progress

The server is running on port 8000, and previous data has been cleared.

Messages from the assistant are received and displayed in real-time.
