Last week at OpenAI's annual developer conference, DevDay, the company unveiled new products, partnerships, and platform upgrades aimed at transforming ChatGPT from a single product into a full operating system for AI applications.
Here are the key highlights from DevDay 2025:
- GPT-5 Pro – The company released what it says is its fastest and most capable model yet (but they say that every time), featuring improved reasoning, longer memory, and multimodal performance across text, image, code, and voice. GPT-5 Pro offers twice the speed of previous models and is available now for ChatGPT Plus and Enterprise users.
- ChatGPT Apps – OpenAI introduced an in-chat app platform that lets developers build interactive experiences directly inside ChatGPT conversations, such as booking travel, managing spreadsheets, or shopping online. A new ChatGPT App Store will allow developers to distribute and monetize their creations. The launch follows its previous attempts to let developers build interactive applications through its GPT Store, however, this new launch puts apps directly in ChatGPT’s responses and lets users call up third-party tools in their everyday conversations. For example, users can now say “Zillow, find me 5 bed 4 bath houses in Waynesville NC for under $1M” to call up the Zillow app.
- AgentKit – A new toolkit that allows developers to create autonomous agents capable of executing multi-step tasks, integrating with third-party apps, and operating independently to complete objectives such as scheduling, research, or workflow automation.
- Model Context Protocol (MCP) Expansion – MCP now supports real-time read/write data access, letting ChatGPT and custom agents interact directly with external databases, APIs, and productivity tools like CRMs or file systems, bridging the gap between chat and action.
- Sora 2 – OpenAI debuted its next-generation video model capable of generating longer, higher-resolution, and more consistent scenes from text prompts, positioning it as a creative tool for filmmakers, advertisers, and content studios. I covered that release in detail last week.
- Codex Revival – The company relaunched its code-generation engine with expanded language support, deeper context awareness, and integration into ChatGPT, enabling natural-language coding assistance and debugging.
- AMD Partnership – OpenAI announced a multi-billion-dollar collaboration with AMD to develop new AI hardware optimized for inference workloads, reducing dependence on NVIDIA and improving scalability for enterprise clients.
- Enterprise & Ecosystem Growth – OpenAI unveiled deeper integrations with Microsoft 365, Salesforce, and Notion, alongside new safety frameworks and education tools for responsible AI deployment.
- Vision for the Future – CEO Sam Altman described the shift from “AI as a tool to AI as an ecosystem,” where developers, businesses, and consumers interact through connected agents and embedded apps — effectively transforming ChatGPT into the operating system for everyday AI.
OpenAI didn’t share details around any revenue-share agreements with Figma, Canva, Zillow, Spotify, or any of the other apps it highlighted in its examples, but given its recent efforts around e-commerce, advertising, and commissions, I'd imagine the company is building its app model to be revenue driving from day one. If not, it's going to run out of cash to burn.
