Web Technology refers to the various tools and techniques that are utilized in the process of communication between different types of devices over the Internet. A web browser is used to access web pages. Web browsers can be defined as programs that display text, data, pictures, animation, and video on the Internet. Hyperlinked resources on the World Wide Web can be accessed using software interfaces provided by Web browsers.

Web Technology can be Classified into the Following Sections:

• World Wide Web (WWW): The World Wide Web is based on several different technologies: Web browsers, Hypertext Markup Language (HTML), and Hypertext Transfer Protocol (HTTP).
• Web Browser: The web browser is an application software to explore www (World Wide Web). It provides an interface between the server and the client and requests to the server for web documents and services.
• Web Server: Web server is a program which processes the network requests of the users and serves them with files that create web pages. This exchange takes place using Hypertext Transfer Protocol (HTTP).
• Web Pages: A webpage is a digital document that is linked to the World Wide Web and viewable by anyone connected to the internet has a web browser.
• Web Development: Web development refers to the building, creating, and maintaining of websites. It includes aspects such as web design, web publishing, web programming, and database management. It is the creation of an application that works over the internet i.e. websites.

Web Development can be Classified into Two Ways:

Frontend Development Languages

The front-end portion is built by using some languages which are discussed below:

• HTML: HTML stands for Hypertext Markup Language. It is used to design the front-end portion of web pages using a markup language. HTML is the combination of Hypertext and Markup language. Hypertext defines the link between the web pages. The markup language is used to define the text documentation within the tag which defines the structure of web pages.
• CSS: Cascading Style Sheets fondly referred to as CSS is a simply designed language intended to simplify the process of making web pages presentable. CSS allows you to apply styles to web pages. More importantly, CSS enables you to do this independent of the HTML that makes up each web page.
• JavaScript: JavaScript is a famous scripting language used to create magic on the sites to make the site interactive for the user. It is used to enhancing the functionality of a website to running cool games and web-based software.
• AJAX: Ajax is an acronym for Asynchronous Javascript and XML. It is used to communicate with the server without refreshing the web page and thus increasing the user experience and better performance.

There are many other languages through which one can do front-end development depending upon the framework for example Flutter user Dart , React uses JavaScript and Django uses Python , and much more.

Front End Frameworks and Libraries

• Angular Material UI
• jQuery EasyUI
• React Desktop
• React Rebass
• React Bootstrap
• React Reactstrap
• React.js Evergreen

Backend Development Languages

The back end portion is built by using some languages which are discussed below:

• PHP: PHP is a server-side scripting language designed specifically for web development. Since PHP code executed on the server-side, so it is called a server-side scripting language.
• Node.js: Node.js is an open-source and cross-platform runtime environment for executing JavaScript code outside a browser. You need to remember that NodeJS is not a framework, and it’s not a programming language. Most people are confused and understand it’s a framework or a programming language. We often use Node.js for building back-end services like APIs like Web App or Mobile App. It’s used in production by large companies such as Paypal, Uber, Netflix, Wallmart, and so on.
• Python: Python is a programming language that lets you work quickly and integrate systems more efficiently.
• Ruby: Ruby is a dynamic, reflective, object-oriented, general-purpose programming language. Ruby is a pure Object-Oriented language developed by Yukihiro Matsumoto. Everything in Ruby is an object except the blocks but there are replacements too for it i.e procs and lambda. The objective of Ruby’s development was to make it act as a sensible buffer between human programmers and the underlying computing machinery.
• Java: Java is one of the most popular and widely used programming languages and platforms. It is highly scalable. Java components are easily available.
• JavaScript: JavaScript can be used as both (front end and back end) programming.
• Golang: Golang is a procedural and statically typed programming language having the syntax similar to C programming language. Sometimes it is termed as Go Programming Language.
• C#: C# is a general-purpose, modern and object-oriented programming language pronounced as “C sharp”.
• DBMS: The software which is used to manage database is called Database Management System (DBMS).

Back End Frameworks and Technology

• Framework: Laravel
• CMS: WordPress
• Framework: Express
• Framework: Django
• Package Manager: Python PIP
• Framework: Ruby on Rails
• Framework: Spring, Hibernate
• Framework: .NET
• Postgre SQL

Data Format

Format of data is used by web applications to communicate with each other. It is light weight text based data interchange format which means, it is simpler to read and write.

Below are two common data formats used in web development:

• XML: Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
• JSON: JSON or JavaScript Object Notation is a format for structuring data.

API: API is an abbreviation for Application Programming Interface which is a collection of communication protocols and subroutines used by various programs to communicate between them.

Web Protocols

Web protocols are set of rules followed by everyone communicating over the web.

• HTTP: The Hypertext Transfer Protocol (HTTP) is designed to enable communications between clients and servers. HTTP works as a request-response protocol between a client and server. A web browser may be the client, and an application on a computer that hosts a web site may be the server.
• TCP/IP Model

Graphical elements are one of the key feature of any webpage. They can be used to convey important points better than text does and beautify the webpage.

• Canvas: The HTML “canvas” element is used to draw graphics via JavaScript.
• SVG: SVG stands for Scalable Vector Graphics. It basically defines vector-based graphics in XML format.

Introduction to Web Technology SWE 444 Internet and Web Application Development Dr. Ahmed Youssef

Internet It is a network of networks connected and communicating using TCP/IP communication protocol

Computer Networks Ahmed Youssef:: SWE444: Internet and Web Application Development

Brief History of the Internet • 1968 - DARPA (Defense Advanced Research Projects Agency) contracts with BBN (Bolt, Beranek & Newman) to create ARPAnet • 1970 - First five nodes: • UCLA • Stanford • UC Santa Barbara • U of Utah, and • BBN • 1974 - TCP specification by Vint Cerf • 1984 – On January 1, the Internet with its 1000 hosts converts to using TCP/IP for its messaging

A Brief Summary of the Evolution of the Internet ??? Assignment

Intranet & Extranets • Intranet • A private network contained within an organization or business used to share information and resources among coworkers. • Extranet • A private network that securely shares part of an organization’s information or operations with external partners

Intranet & Extranets

Intranet & Extranets Ahmed Youssef:: SWE444: Internet and Web Application Development

Components of Web • Web Page and Web Site • Web Browsers and Web Servers • Uniform Resource Locator(URL) • HTML • HTTP • Internet Protocol

Web Page vs Website • A web page is a part of a complete web site. It is a document or information resource that is suitable for the World Wide Web and it can be accessed through a web browser. • Websites can consist of few web pages or many hundreds of web pages. Ahmed Youssef:: SWE444: Internet and Web Application Development

It's a software It lets you visit webpages and use web applications Types: Internet Explorer Mozilla Firefox Netscape Navigator Google Chrome Opera … Web Browser

Web servers • The term web server can refer to either the hardware (computer) or the software (computer application) that helps to deliver web content that can be accessed through the Internet. • The web server hosts pages, programs, and multimedia files and serves them using HTTP, a protocol designed to send files to web browsers and other protocols.

Accessing a web site

HTMLHyperText Markup Language HTML is a coding language used to create hypertext/hypermedia documents known as web pages. Hypertext documents are documents that can contain links to other hypertext documents. Ahmed Youssef:: SWE444: Internet and Web Application Development 14

HTTP Hypertext Transfer Protocol Provides a standard for Web browsers and servers to communicate. Set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. Ahmed Youssef:: SWE444: Internet and Web Application Development 15

Hypertext Transport Protocol (HTTP) Protocol for HTML retrieval of and other documents from website throughout the Internet. HTTP is based on the request-response communication model: Client sends a request Server sends a response 16

Client Server Server Request Response Client Client Client

Client Program Server Program Client PC Client/Server Computing Client/Server Processing with Request-Response Cycle Request Message Response Message File Server

Client is Browser Server Program Web-Enabled Application HTTP Request Message HTTP Response Message Web-enabled applications: Form of client server processing that uses browsers as clients. Client PC E-Mail Server

Internet Protocols What is a protocol? • A set of rules governing the exchange of data between two or more hosts. • The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet.

Internet Protocol address(IP address) • It is a usually numerical label assigned to each device participating in a computer network that uses the Internet Protocol for communication. • IP address: • 32-bit number (in IPv4) • Written as four dot-separated bytes, • e.g. 212.138.86.31 (www.uoh.edu.sa)

Transmission Control Protocol (TCP) • TCP enables two hosts to establish a connection and exchange streams of data. • Provides guarantee that packets delivered • Provide two-way (full duplex) communication

TCP { Source Destination Can I talk to you? Establish connection. OK. Can I talk to you? OK. { Here’s a packet. Send packet with acknowledgment. Got it. { Here’s a packet. Resend packet if no (or delayed) acknowledgment. Here’s a resent packet. Got it.

Uniform Resource Locator URL is a standard way to specify the location of a resource URLs are the unique addresses of Internet Resources. A URL is divided into four parts. • Transfer protocols • Server name • Directory path • File name 24

General URL syntax • <scheme>:<scheme-dependent-information> • Scheme examples: • http (Hyper Text Transfer Protocol) • ftp (File Transfer Protocol) • news (News protocol) • scheme://Server name/path/filename

Example http://www.uoh.edu.sa/a.khedr/swe444.html Transfer Protocol: Server name: Directory Path: File name: Ahmed Youssef:: SWE444: Internet and Web Application Development 26

Domain Name Service (DNS) • DNS is the “phone book” for the Internet • Map between host names and IP addresses • Host names • Labels separated by dots, e.g., www.example.org • Final label is top-level domain • Generic: .com, .org, etc. • Country-code: .us, .sa, .eg, etc. http://en.wikipedia.org/wiki/List_of_Internet_top-level_domains

Types of Web Sites • Static: • It contains a fixed amount of pages and the information is presented in HTML. • Dynamic: • the content changes every time the page loads. This change in content will directly be related to the latest updated information present on the database . Ahmed Youssef:: SWE444: Internet and Web Application Development

Accessing static web pages • “Static” – the contents don’t change (unless they’re edited). • Web pages (text files) and other needed files (e.g. images) are stored as files on the web server and are retrieved as needed in response to HTTP requests

Types of web sites based on content • Information • Search Engines • Educational • Forums • Company • Online shops • … Ahmed Youssef:: SWE444: Internet and Web Application Development

The World Wide Web (WWW) • The World Wide Web consists of all the public Web sites connected to the Internet worldwide • The Web consists of three distinct technologies • Hyper Text Mark-up Language (HTML) • Hyper Text Transport Protocol (HTTP) • Uniform Resource Locators (URLs)

Difference Between Internet and Web? • World Wide Web is the Multimedia portion of the Internet • Images, video, sound, animation, etc. • Technically the Web is the portion of the Internet that contains Web Servers, and Web Sites.

Client Caching • A cache is a local copy of information gets from some other source

Client Caching Server Client Browser Web Server 1. HTTP request for image 2. HTTP response containing image 3. Store image Cache

Client Caching Server Client Browser Web Server This… HTTP request for image HTTP response containing image I need that image again… Cache

Client Caching Server Client Browser Web Server I need that image again… Getimage … or this Cache

Client Caching • Cache advantages • (Much) faster than HTTP request/response • Less network traffic • Less load on server • Cache disadvantage • Cached copy of resource may be invalid (inconsistent with remote version)

Secure Servers • Since HTTP messages typically travel over a public network, private information (such as credit card numbers) should be encrypted to prevent eavesdropping • https URL scheme tells browser to use encryption • Common encryption standards: • Secure Socket Layer (SSL) • Transport Layer Security (TLS)

Secure Servers I’d like to talk securely to you (over port 443) Browser TLS/SSL TLS/SSL Web Server HTTP Requests Here’s my certificate and encryption data HTTP Requests Here’s an encrypted HTTP request Here’s an encrypted HTTP response Here’s an encrypted HTTP request HTTP Responses HTTP Responses Here’s an encrypted HTTP response

Google Takes the Next Step in Its A.I. Evolution

The tech giant showed off how it would enmesh A.I. more deeply into its products and users’ lives, from search to so-called agents that perform tasks.

• Share full article

By Nico Grant

Reporting from the Shoreline Amphitheatre in Mountain View, Calif.

Last May, Sundar Pichai, Google’s chief executive, said the company would use artificial intelligence to reimagine all of its products .

But because new generative A.I. technology presented risks, like spreading false information, Google was cautious about applying the technology to its search engine, which is used by more than two billion people and was responsible for $175 billion in revenue last year.

On Tuesday, at Google’s annual conference in Mountain View, Calif., Mr. Pichai showed how the company’s aggressive work on A.I. had finally trickled into the search engine. Starting this week, he said, U.S. users will see a feature, A.I. Overviews, that generates information summaries above traditional search results. By the end of the year, more than a billion people will have access to the technology.

A.I. Overviews is likely to heighten concerns that web publishers will see less traffic from Google Search, putting more pressure on an industry that has reeled from rifts with other tech platforms. On Google, users will see longer summaries about a topic, which could reduce the need to go to another website — though Google downplayed those concerns.

“The links included in A.I. Overviews get more clicks” from users than if they were presented as traditional search results, Liz Reid, Google’s vice president of search, wrote in a blog post . “We’ll continue to focus on sending valuable traffic to publishers and creators.”

The company also unveiled a host of other initiatives — including a lightweight A.I. model, new chips and so-called agents that help users perform tasks — in an effort to gain the upper hand in an A.I. slugfest with Microsoft and OpenAI, the maker of ChatGPT.

“We are in the very early days of the A.I. platform shift,” Mr. Pichai said on Tuesday at Google’s I/O developer conference. “We want everyone to benefit from what Gemini can do,” including developers, start-ups and the public.

When ChatGPT was released in late 2022, some tech industry insiders considered it a serious threat to Google’s search engine, the most popular way to get information online. Since then, Google has aggressively worked to regain its advantage in A.I., releasing a family of technology named Gemini, including new A.I. models for developers and the chatbot for consumers. It also infused the technology into YouTube, Gmail and Docs, helping users create videos, emails and drafts with less effort.

All the while, Google’s tit-for-tat competition with OpenAI and its partner, Microsoft, has continued. The day before Google’s conference, OpenAI presented a new version of ChatGPT that is more akin to a voice assistant .

(The New York Times sued OpenAI and Microsoft in December for copyright infringement of news content related to A.I. systems.)

At its Silicon Valley event, Google showcased how it would enmesh A.I. more deeply into users’ lives. It presented Project Astra, an experiment to see how A.I. could act as an agent, vocally chatting with users and responding to images and videos. Some of the abilities will be available to users of Google’s Gemini chatbot this year, Demis Hassabis, chief executive of DeepMind, Google’s A.I. lab, wrote in a blog post .

DeepMind also presented Gemini 1.5 Flash, an A.I. model designed to be fast and efficient but lighter in size than Gemini 1.5 Pro, the midtier model that Google rolled out to many of its consumer services. Dr. Hassabis wrote that the new model was “highly capable” at reasoning and was good at summarizing information, chatting and captioning images and videos.

The company announced another A.I. model, Veo, that generates high-definition videos based on simple text prompts, similar to OpenAI’s Sora system. Google said that some creators could preview Veo and that others could join a wait-list for access to it. Later this year, the company expects to bring some of Veo’s abilities to YouTube Shorts, the video platform’s TikTok competitor, and other products.

Google also showed off the latest versions of its music-generation tool, Lyria, and image generator, Imagen 3. In February, Google’s Gemini chatbot was criticized by users on social media for refusing to generate images of white people and presenting inaccurate images of historical figures. The company said it would shut off the ability to generate images of people until it fixed the issue.

In the past three months, more than one million users have signed up to Gemini Advanced, the version of Google’s chatbot available through a $20 monthly subscription, the company said.

In the next months, Google will add Gemini Live, which will provide users a way to speak to the chatbot through voice commands. The chatbot will respond in natural-sounding voices, Google said, and users could interrupt Gemini to ask clarifying questions. Later this year, users will be able to use their cameras to show Gemini Live the physical world around them and have conversations with the chatbot about it.

Besides A.I. Overviews, Google’s search engine will present search results pages organized by A.I., with generated headlines highlighting different types of content. The feature will start with dining and recipe results, and will later be offered for shopping, travel and entertainment queries.

Ms. Reid, the head of search, said in an interview before the conference that she expected the search updates to save users time because Google “can do more of the work for you.”

Mr. Pichai said he expected that a vast majority of people would interact with Gemini A.I. technology through Google’s search engine.

“We’re going to make it more and more seamless for people to interact with Gemini,” Mr. Pichai said in a briefing before the conference.

How-To Geek

6 ways to create more interactive powerpoint presentations.

Engage your audience with cool, actionable features.

Quick Links

• Add a QR code
• Embed Microsoft Forms (Education or Business Only)
• Embed a Live Web Page
• Add Links and Menus
• Add Clickable Images to Give More Info
• Add a Countdown Timer

We've all been to a presentation where the speaker bores you to death with a mundane PowerPoint presentation. Actually, the speaker could have kept you much more engaged by adding some interactive features to their slideshow. Let's look into some of these options.

1. Add a QR code

Adding a QR code can be particularly useful if you want to direct your audience to an online form, website, or video.

Some websites have in-built ways to create a QR code. For example, on Microsoft Forms , when you click "Collect Responses," you'll see the QR code option via the icon highlighted in the screenshot below. You can either right-click the QR code to copy and paste it into your presentation, or click "Download" to add it to your device gallery to insert the QR code as a picture.

In fact, you can easily add a QR code to take your viewer to any website. On Microsoft Edge, right-click anywhere on a web page where there isn't already a link, and left-click "Create QR Code For This Page."

You can also create QR codes in other browsers, such as Chrome.

You can then copy or download the QR code to use wherever you like in your presentation.

2. Embed Microsoft Forms (Education or Business Only)

If you plan to send your PPT presentation to others—for example, if you're a trainer sending step-by-step instruction presentation, a teacher sending an independent learning task to your students, or a campaigner for your local councilor sending a persuasive PPT to constituents—you might want to embed a quiz, questionnaire, pole, or feedback survey in your presentation.

In PowerPoint, open the "Insert" tab on the ribbon, and in the Forms group, click "Forms". If you cannot see this option, you can add new buttons to the ribbon .

As at April 2024, this feature is only available for those using their work or school account. We're using a Microsoft 365 Personal account in the screenshot below, which is why the Forms icon is grayed out.

Then, a sidebar will appear on the right-hand side of your screen, where you can either choose a form you have already created or opt to craft a new form.

Now, you can share your PPT presentation with others , who can click the fields and submit their responses when they view the presentation.

3. Embed a Live Web Page

You could always screenshot a web page and paste that into your PPT, but that's not a very interactive addition to your presentation. Instead, you can embed a live web page into your PPT so that people with access to your presentation can interact actively with its contents.

To do this, we will need to add an add-in to our PPT account .

Add-ins are not always reliable or secure. Before installing an add-in to your Microsoft account, check that the author is a reputable company, and type the add-in's name into a search engine to read reviews and other users' experiences.

To embed a web page, add the Web Viewer add-in ( this is an add-in created by Microsoft ).

Go to the relevant slide and open the Web Viewer add-in. Then, copy and paste the secure URL into the field box, and remove https:// from the start of the address. In our example, we will add a selector wheel to our slide. Click "Preview" to see a sample of the web page's appearance in your presentation.

This is how ours will look.

When you or someone with access to your presentation views the slideshow, this web page will be live and interactive.

4. Add Links and Menus

As well as moving from one slide to the next through a keyboard action or mouse click, you can create links within your presentation to direct the audience to specific locations.

To create a link, right-click the outline of the clickable object, and click "Link."

In the Insert Hyperlink dialog box, click "Place In This Document," choose the landing destination, and click "OK."

What's more, to make it clear that an object is clickable, you can use action buttons. Open the "Insert" tab on the ribbon, click "Shape," and then choose an appropriate action button. Usefully, PPT will automatically prompt you to add a link to these shapes.

You might also want a menu that displays on every slide. Once you have created the menu, add the links using the method outlined above. Then, select all the items, press Ctrl+C (copy), and then use Ctrl+V to paste them in your other slides.

5. Add Clickable Images to Give More Info

Through PowerPoint's animations, you can give your viewer the power to choose what they see and when they see it. This works nicely whether you're planning to send your presentation to others to run through independently or whether you're presenting in front of a group and want your audience to decide which action they want to take.

Start by creating the objects that will be clickable (trigger) and the items that will appear (pop-up).

Then, select all the pop-ups together. When you click "Animations" on the ribbon and choose an appropriate animation for the effect you want to achieve, this will be applied to all objects you have selected.

The next step is to rename the triggers in your presentation. To do this, open the "Home" tab, and in the Editing group, click "Select", and then "Selection Pane."

With the Selection Pane open, select each trigger on your slide individually, and rename them in the Selection Pane, so that they can be easily linked to in the next step.

Finally, go back to the first pop-up. Open the "Animations" tab, and in the Advanced Animation group, click the "Trigger" drop-down arrow. Then, you can set the item to appear when a trigger is clicked in your presentation.

If you want your item to disappear when the trigger is clicked again, select the pop-up, click "Add Animation" in the Advanced Animation group, choose an Exit animation, and follow the same step to link that animation to the trigger button.

6. Add a Countdown Timer

A great way to get your audience to engage with your PPT presentation is to keep them on edge by adding a countdown timer. Whether you're leading a presentation and want to let your audience stop to discuss a topic, or running an online quiz with time-limit questions, having a countdown timer means your audience will keep their eye on your slide throughout.

To do this, you need to animate text boxes or shapes containing your countdown numbers. Choose and format a shape and type the highest number that your countdown clock will need. In our case, we're creating a 10-second timer.

Now, with your shape selected, open the "Animations" tab on the ribbon and click the animation drop-down arrow. Then, in the Exit menu, click "Disappear."

Open the Animation Pane, and click the drop-down arrow next to the animation you've just added. From there, choose "Timing."

Make sure "On Click" is selected in the Start menu, and change the Delay option to "1 second," before clicking "OK."

Then, with this shape still selected, press Ctrl+C (copy), and then Ctrl+V (paste). In the second box, type 9 . With the Animation Pane still open and this second shape selected, click the drop-down arrow and choose "Timing" again. Change the Start option to "After Previous," and make sure the Delay option is 1 second. Then, click "OK."

We can now use this second shape as our template, as when we copy and paste it again, the animations will also duplicate. With this second shape selected, press Ctrl+C and Ctrl+V, type 8 into the box, and continue to do the same until you get to 0 .

Next, remove the animations from the "0" box, as you don't want this to disappear. To do this, click the shape, and in the Animation Pane drop-down, click "Remove."

You now need to layer them in order. Right-click the box containing number 1, and click "Bring To Front." You will now see that box on the top. Do the same with the other numbers in ascending order.

Finally, you need to align the objects together. Click anywhere on your slide and press Ctrl+A. Then, in the Home tab on the ribbon, click "Arrange." First click "Align Center," and then bring the menu up again, so that you can click "Align Middle."

Press Ctrl+A again to select your timer, and you can then move your timer or copy and paste it elsewhere.

Press F5 to see the presentation in action, and when you get to the slide containing the timer, click anywhere on the slide to see your countdown timer in action!

Now that your PPT presentation is more interactive, make sure you've avoided these eight common presentational mistakes before you present your slides.

OpenAI’s new GPT-4o lets people interact using voice or video in the same model

The company’s new free flagship “omnimodel” looks like a supercharged version of assistants like Siri or Alexa.

OpenAI just debuted GPT-4o, a new kind of AI model that you can communicate with in real time via live voice conversation, video streams from your phone, and text. The model is rolling out over the next few weeks and will be free for all users through both the GPT app and the web interface, according to the company. Users who subscribe to OpenAI’s paid tiers, which start at $20 per month, will be able to make more requests. 

OpenAI CTO Mira Murati led the live demonstration of the new release one day before Google is expected to unveil its own AI advancements at its flagship I/O conference on Tuesday, May 14. 

GPT-4 offered similar capabilities, giving users multiple ways to interact with OpenAI’s AI offerings. But it siloed them in separate models, leading to longer response times and presumably higher computing costs. GPT-4o has now merged those capabilities into a single model, which Murati called an “omnimodel.” That means faster responses and smoother transitions between tasks, she said.

The result, the company’s demonstration suggests, is a conversational assistant much in the vein of Siri or Alexa but capable of fielding much more complex prompts.

“We’re looking at the future of interaction between ourselves and the machines,” Murati said of the demo. “We think that GPT-4o is really shifting that paradigm into the future of collaboration, where this interaction becomes much more natural.”

Barret Zoph and Mark Chen, both researchers at OpenAI, walked through a number of applications for the new model. Most impressive was its facility with live conversation. You could interrupt the model during its responses, and it would stop, listen, and adjust course. 

OpenAI showed off the ability to change the model’s tone, too. Chen asked the model to read a bedtime story “about robots and love,” quickly jumping in to demand a more dramatic voice. The model got progressively more theatrical until Murati demanded that it pivot quickly to a convincing robot voice (which it excelled at). While there were predictably some short pauses during the conversation while the model reasoned through what to say next, it stood out as a remarkably naturally paced AI conversation. 

The model can reason through visual problems in real time as well. Using his phone, Zoph filmed himself writing an algebra equation (3 x + 1 = 4) on a sheet of paper, having GPT-4o follow along. He instructed it not to provide answers, but instead to guide him much as a teacher would.

“The first step is to get all the terms with x on one side,” the model said in a friendly tone. “So, what do you think we should do with that plus one?”

Like previous generations of GPT, GPT-4o will store records of users’ interactions with it, meaning the model “has a sense of continuity across all your conversations,” according to Murati. Other new highlights include live translation, the ability to search through your conversations with the model, and the power to look up information in real time. 

As is the nature of a live demo, there were hiccups and glitches. GPT-4o’s voice might jump in awkwardly during the conversation. It appeared to comment on one of the presenters’ outfits even though it wasn’t asked to. But it recovered well when the demonstrators told the model it had erred. It seems to be able to respond quickly and helpfully across several mediums that other models have not yet merged as effectively. 

Previously, many of OpenAI’s most powerful features, like reasoning through image and video, were behind a paywall. GPT-4o marks the first time they’ll be opened up to the wider public, though it’s not yet clear how many interactions you’ll be able to have with the model before being charged. OpenAI says paying subscribers will “continue to have up to five times the capacity limits of our free users.”
