OpenAI’s “Big Reveal” at DevDay 2025 was focused on introducing AgentKit, a comprehensive toolkit designed to make building, deploying, and optimizing AI agents much easier for both developers and enterprises.

AgentKit enables rapid agent creation from prototype to production, streamlining workflow design, evaluation, and integration without requiring heavy coding or disparate tools.

What is AgentKit?

AgentKit is a fully integrated suite that brings together several components to simplify agent development:Agent Builder: A visual, drag-and-drop canvas (similar to Canva for workflows) for designing and managing logic, steps, and multi-agent workflows, complete with versioning and guardrails.

Connector Registry: A central hub for connecting data sources, APIs, and tools, managed via an admin console to ensure secure integration across OpenAI products.

ChatKit: A customizable chat interface toolkit that lets developers easily embed agentic chat experiences inside their own products or websites.

Key Advantages developers and enterprises can now create and test agent logic visually—no code is required for initial setups, allowing faster prototyping.

Built-in evaluation tools include datasets, trace grading (step-by-step agent decision analysis), automated prompt optimization, and support for third-party model testing.

The toolkit leverages the existing OpenAI Responses API and Agents SDK, making workflows more reliable and deeply integrated within OpenAI’secosystem.

Announcements and Industry Impact the launch is viewed as a major step in bringing agentic AI mainstream, moving beyond chatbots to agents capable of handling complex, autonomous tasks for enterprises.

OpenAI also announced new features for the Codex model (now trained on GPT-5), upgraded agent evaluation tools, and introduced app-building capabilities directly inside ChatGPT.

Notably, this event signaled OpenAI’s intention to compete with other no-code and agent platforms while opening new possibilities for how businesses and consumers can harness AI agents.

How to Get Started developers can access Agent through the OpenAI platform, where guides and documentation are available for building agents visually, embedding chat experiences, and managing connectors.

Real-world case studies include Klarna (handling customer support tickets) and Clay (driving sales automation), evidencing substantial enterprise adoption.

OpenAI’s AgentKit lays the foundation for anyone—from startups to large enterprises—to deploy tailored, multi-agent workflows, featuring robust evaluation and seamless integrations, redefining what it means to work with AI-powered applications.

Welcome to The Atlas, we’re glad you’re here. This week, AI started to build its own tools.

From OpenAI’s AgentKit to Microsoft’s self-running spreadsheets, the story of AI is shifting from capability to coordination. Systems are starting to manage workflows, reason across domains, and collaborate with their users.

How OpenAI’s Agent kit Teaches Machines to Work Together

At Dev Day 2025, OpenAI introduced AgentKit, a toolkit designed to help developers build, test, and refine AI agents without needing sprawling infrastructure. The live demo drew a full-house crowd as Christina Huang assembled a functional agent in eight minutes, previewing what OpenAI calls a “production-ready agent workflow.”

Inside the release:

• AgentBuilder gives developers a visual space to map an agent’s reasoning, using nodes and logic to design behavior.

• ChatKit provides an embeddable chat interface that can live inside any product, letting users interact with agents naturally.

• Evals measures performance and reliability through tracing, dataset testing, and prompt optimization.

• Connector Registry links agents to APIs and internal systems so they can act inside real workflows.

According to those who have seen early previews:

• The interface resembles a creative studio for AI logic.

• Templates allow quick setup for tasks such as document review, customer support, and data processing.

• Each component connects visually, forming a live network of models and tools that can exchange information.

• Integrations with frameworks like MCP and ChatKit appear central to its design.

This movement marks OpenAI’s move from single-use chat models toward continuous, self-managing intelligence.

It may also set the stage for a new wave of “AI-native” work environments built entirely around autonomous systems.

OpenAI’s Sam Altman called it “a bridge from prototype to production.” What he really meant was a way to turn intelligence itself into a buildable material.

AI Browser Wars: Perplexity’s Comet is Here, But Is It Secure?

The Internet is Better on Comet

Today we are releasing the Comet browser to the world, for free.

We first launched Comet to limited release on July 9.  Ever since, millions of people have joined the waitlist to receive Comet, faster than we’ve been able to release it. It has become the most sought-after AI product of the year, no matter how fast we release invites. 

Meanwhile, users with Comet access are working with it in powerful ways we never expected, and the results are clear: people love Comet. 

We want everyone to have the choice to use Comet. Beginning today, you can now download it for free, at perplexity.ai/comet. 

Everything great begins with a question

We’ve always believed that curious people lead the world. That conviction guided everything we’ve built—and today, we’re excited to share a series of announcements that build on each other to create a radically better internet.

In the 1950s, there were as many telephone engineers as there are computer science engineers today.  But only three of them invented the transistor and gave birth to computing. They were curious. They dared to ask, “Can we make a vacuum tube that never breaks and stays cool?” The Wright brothers were not inventors or engineers, they were relentlessly curious. They never stopped asking how to fly. With curiosity, they flew.  

It’s always been this way. In your work, your community, your relationships–every great vision begins with questions. 

The internet is broken. 

Today, the internet has stifled our curiosity. Knowledge work taught us to have answers, not questions. The clicks and traffic model of the web has done nothing but convert it into a digital yellow pages, where every path leads to a checkout button. Wherever you are on the internet today, you’re in somebody’s purchase funnel.  

People want a better internet. Comet is proof.

We’ve learned a lot since first making Comet available to furiously releasing it to the waitlist. When Perplexity users first downloaded Comet, the number of questions they asked increased by 6-18X in the first day. Curiosity is in all of us.

Suddenly, asking new questions is easier, the delightful default-mode of internet use. We learned: the internet is better on Comet.

Your AI, not the AI

The second thing we learned is people love the Comet Assistant. The Comet Assistant browses the internet with you, there for any questions or tasks you think of along the way. It helps you with everything: research, meetings, code, e-commerce, and more. You can stay in your flow and get real answers, helpful actions, fewer distractions.  

In the earliest days of the “Comet Summer,” it was clear the Comet Assistant should be able to do new tasks in any new tab. We shipped at Perplexity velocity.  Every new tab has a new Comet Assistant there to answer any question or take any action on your behalf. All you have to do is ask.

Then, we had a new question: is a chat bot the right paradigm for the world’s most powerful personal AI assistant? 

Chat bots are outdated

Last week we announced a powerful AI assistant that breaks the chat bot mold: Email Assistant.

A Personal Assistant for Your Inbox

Introducing Email Assistant

Today we’re launching Perplexity Email Assistant, exclusive for Perplexity Max subscribers. Email Assistant brings a powerful personal assistant to your email, transforming your inbox to action.  

Perplexity Max subscribers have shown powerful adoption of the Comet Assistant that launched with Comet and Comet Max Assistant launched in July exclusively for Max subscribers. In fact, early data shows the Comet assistants increase the number of questions and tasks users accomplish per day by 3-18X.  

Simply put, a powerful and personal AI assistant helps you get a lot more done.  

Your inbox deserves the same intelligent partnership, which is why we’ve built Perplexity Email Assistant. Email Assistant connects directly with your email account across your phone and computer. It drafts replies, organizes messages, schedules meetings, and more. 

You power through inbox tasks, in less time, while staying in control.

A powerful, personal assistant

Email is more than a message center. Your inbox contains your professional memory, your relationships, calendaring, and coordination. Meanwhile, your outbox is your productivity and your reputation.  

The most successful workers and thinkers hire personal assistants for their email instead of relying on AI tools and algorithms that handle rote tasks. There’s too much at stake. Perplexity’s Email Assistant is more than a tool, and available to anyone.  

Email Assistant learns your communication style and priorities. It drafts responses matching your tone and suggests meeting times based on your calendar preferences, saving time on routine tasks.

Email Assistant is also secure. Email Assistant is SOC 2 and GDPR compliance by default and never trains on your data. 

Just ask

Beginning today, Max Subscribers can sign up for Email Assistant here. Then get started simply by emailing assistant@perplexity.com from your own inbox. The email assistant knows it’s you and gets right to work.

Calendar meetings by cc’ing your assistant on any email. The assistant will work with your contacts in your style on the back-and-forth exchanges that steal hours from your day, all while ensuring you still have total control.  

You can also ask your Email Assistant questions about your inbox: “What emails should I prioritize before my board meeting?” “Summarize all messages about the Q4 budget.” “Show me anything urgent from the design team this week.” Comet users already enjoy this capability, where questions can be asked of any web interface. 

Email assistant powers your curiosity beyond predefined functions. Ask anything about your inbox and discover new ways to extract value from your email data. The more you ask, the more you uncover possibilities we haven’t even considered yet.

Work smarter, faster

Email Assistant connects with Gmail and Outlook. Smart labels automatically organize your inbox, showing what’s completed, what needs action, and what requires your attention. No more scanning hundreds of messages to find what’s critical.

Another benefit is auto-draft. Email Assistant writes responses for you to edit or send, eliminating the biggest email bottleneck: getting started. 

Email Assistant adapts to your communication patterns and priorities. It drafts responses matching your tone, suggests meeting times based on your calendar habits, and applies labels you actually use. Every interaction teaches it to work more like you would.

Built for you

Email Assistant works where you work, answering the questions that drive your most important decisions. It’s built to help you focus on what matters, no matter where. The time you reclaim from routine correspondence and rote tasks in your inbox becomes time for deeper work, meaningful conversations, and even bigger questions.

Email Assistant is available now for Perplexity Max subscribers. Just go to the Email Assistant hub and connect your email.

Then, start with a simple question: “What needs my attention first?”  Add your email assistant to any conversation, and turn your inbox into action.

Working with it is simple: just cc your email assistant on any thread to complete scheduling and other tasks, have draft replies ready for you when you open your inbox, and email the assistant with anything you need from your inbox.  

And we are just warming up. Today, Perplexity is announcing Background Assistants. 

Background Assistants work for you simultaneously and asynchronously, so you can focus on what matters.  In the background, your personal team of AI assistants eliminates any task on your to-do list. Background Assistants are a platform where your curiosity becomes productivity.

Whether your assistants work in your browser, your inbox, or the background, you need to manage them from wherever you are. That’s why we recently announced the first previews of Comet for mobile. 

Curiosity is everywhere

So far, Comet has been desktop-only. A mobile app is easy to build, while a mobile AI assistant and powerful curiosity accelerator takes careful thought.  Soon, the Comet mobile app will be available on any device, with a personal AI designed for your phone.

Comet strips away the clutter and frustration of mobile ads and outdated app models. And, with industry-leading voice technology, your interface with Comet assistants is easier than ever.

A better internet needs better content

Of course, technology alone can’t make the internet better—the quality of what’s online matters even more. Instead of just feeding the content machine, we’re championing real journalism. That’s why we built Comet Plus.

Today we announced our inaugural participating publishers in Comet Plus. They include some of the world’s most reputable sources of news and information.

Announcing Comet Plus Launch Partners

Today, we’re proud to unveil the initial launch partners for Comet Plus. Comet Plus is the new business model designed by Perplexity to deliver premium journalism to a more curious, empowered internet and ensure publishers benefit from the new demands of the AI age.

What is Comet Plus?

Comet Plus is our answer to the critical question: What does a better internet look like in the age of AI? Comet Plus is a $5 standalone subscription (included at no additional cost with Perplexity Pro and Max) that gives users and their AI assistants direct access to high-quality journalism and answers supported by trusted and accurate reporting. Participating publishers are compensated according to each of the three ways their participating content is valuable in the age of AI.  (Read all the details about Comet Plus and the new model we announced for publisher compensation.)

Publishers are at the center of our vision for a better internet.

The web was created for questions and curiosity, but somewhere along the way, users were funneled into clickbait, misinformation, and low-quality content optimized for an era of clicks and traffic.

At Perplexity, we believe in a better internet. That’s why we built Comet. The internet is already better on Comet, but a truly better internet must also reward accurate, well-written news that fuels more accurate AI answers and builds the trust that readers place in their AI assistants.

Our vision with Comet and Comet Plus is to create the business model that enables this: Publishers participating in Comet Plus are compensated according to human and AI-driven interactions with their participating content, shifting away from the “pageview at any cost” model that has undermined quality journalism for years.

Meet our Comet Plus launch partners.

We are honored to launch Comet Plus with some of the world’s best-known, most respected sources of news and culture:

CNN

Conde Nast, publishers of The New Yorker, Wired, Architectural Digest, Allure, Ars Technica, Bon Appétit, Condé Nast Traveler, Epicurious, GQ, Glamour, Pitchfork, Self, Teen Vogue, them, Vanity Fair, and Vogue.

Fortune

Le Figaro

Le Monde

The Los Angeles Times

The Washington Post

The participation of these leading publishers means Comet Plus users get immediate, frictionless access to premium stories that matter, from global headlines to in-depth analysis and exceptional cultural writing all directly on the web as part of the Comet browsing experience.

The agentic internet is for people

A better internet starts with Comet. With Comet Plus, a better internet includes the expertise and perspective of top journalists and publishers. 

Most importantly, Comet Plus makes the internet better by ensuring great publishers and journalists benefit from the new forms of usage people demand in the age of AI. At the same time, Comet Plus is specifically designed to allow publishers to own the direct relationship with their audience.

We’re building an ecosystem that rewards trust, accuracy, and curiosity, so everyone can confidently ask bigger, better questions, and get the best answers that move them forward.

We’re grateful to our launch partners for believing in this vision. Together, we are supporting the world’s curiosity.

Our mission, from day one, has been to support the world’s curiosity. We do it by building AI products that are truly useful, so you can ask more of the world.
