By skyforbes AI monetization platform Dappier overviews the latest updates from OpenAI as part of the orgs’ second ever Dev Day.
An overview to AI building & monetization following OpenAI Dev Day 2025
On October 6, 2025, OpenAI hosted Dev Day 2025, its second major developer conference. The event has followed key launches from the org in the past year: mixed reception to the launch of ChatGPT-5 , the debut of Sora 2 — a hyper-realistic video generation model whose app now includes its own social feed for user-generated AI clips — and Instant Checkout, OpenAI’s native in-chat purchasing experience.
At Dev Day, OpenAI announced three new defining updates:
- The ChatGPT Apps SDK, allowing developers to build in-chat apps;
- The AgentKit framework for agentic AI development; and
- A new stack of GPT-5 Pro, Sora 2, and real-time voice models, setting the stage for AI-driven commerce inside ChatGPT.
Dappier’s AI monetization platform helps you transition to the agentic web & make money with AI. Dozens of web publishers from brands like Benzinga, Wild Sky Media’s parenting and lifestyle brands like CafeMom & Mom.com, and the News-Press & Gazette company harness Dappier to monetize AI.
Our guide below to the new ChatGPT updates overview what was announced and tell you what you need to know as part of your AI strategy.
The ChatGPT Apps SDK: Turning Websites into In-Chat Experiences
What’s new
OpenAI unveiled the ChatGPT Apps SDK, enabling developers to create apps that run directly within ChatGPT. Launch partners include Canva, Spotify, Expedia, Zillow, Booking.com, Figma, and Coursera, with more expected soon. Developers will be able to submit their own apps later this year, complete with monetization and discovery features.
What it means
This reimagines how the web works. Users are going to increasingly turn to AI as their first stop online, with a ChatGPT app executing multi-step tasks on your behalf.
AI is the new the front door.
For developers, this is both a massive opportunity and a structural shift: visibility now depends on making content available via AI systems.
AgentKit: The Framework for Agentic AI
What’s new
OpenAI introduced AgentKit, a suite for building autonomous agents capable of performing real tasks through APIs and workflows. It includes:
- Agent Builder — a visual canvas for logic and behavior
- Connector Registry — integration layer for tools and data
- ChatKit — infrastructure for conversational interfaces
What it means
AgentKit moves AI from “assistant” to operator. Developers can now deploy agents that act independently. Agent Builder lets developers build workflows and agents that connect to tools and MCP servers like Dappier MCP, enabling no-code automations to be truly complex. With Dappier MCP, agents can reason over the latest verified breaking news, financial data, academic research & more.
The shift will require new design principles with thoughtful orchestration and rigorous guardrails, but AgentKit opens the door to truly dynamic, multi-step automation.
GPT-5 Pro, Sora 2, and Real-Time Voice: The New Model Stack
What’s new
OpenAI rolled out:
- GPT-5 Pro, a higher-reasoning model available via API;
- Sora 2, offering cinematic-quality video and synchronized audio;
- gpt-realtime mini, a low-latency voice model for live conversation;
- And a major Codex update with in-Slack collaboration and editable code via prompts.
What it means
Together, these models turn ChatGPT into a multimedia, multimodal platform. Apps can now blend text, video, voice, and code — enabling interactive learning, AI-generated marketing, and personalized media.
For developers, that means building experiences that are conversational — fast, natural, and ready to be integrated into any endpoint — with audio and visual interaction coming into play just as much as text.
The Commerce Layer: ChatGPT as an Operating System
What’s new
OpenAI previewed agentic commerce, where users can discover, purchase, and complete transactions entirely inside ChatGPT. Payments and fulfillment will be handled in-chat, without redirects.
What it means
ChatGPT is evolving into an operating system for transactions — blending search, recommendations, and checkout into a single interface.
For brands and developers:
- Your ChatGPT app becomes your storefront.
- Conversion design shifts from page optimization to conversational design.
- Attribution and fulfillment models must adapt to in-chat commerce.
