OpenAI just wrapped its DevDay 2025, where CEO Sam Altman and the team laid out a bold vision for how AI will evolve, and how developers will build with it. So in this article, I have talked about the six key announcements that caught everyone’s attention.
1. GPT-5 Pro and GPT-Realtime-Mini
Altman started the day by introducing GPT-5 Pro, a more powerful version of OpenAI’s flagship model, and gpt-realtime-mini, which supports real-time voice interactions. Both tools are being made available to developers through the API. In Altman’s words, these are meant to become the standard ways people “talk to AI.” In practice, that means less waiting, more fluid conversation, and higher expectations for what conversational interfaces can do.
2. Sora 2
The newly revealed Sora 2 upgrades OpenAI’s video generation toolkit by adding realistic soundscapes and synchronized audio. Which means no more lip-sync mismatches or awkward silence when there should be ambiance. The Sora 2 is now accessible through the API and allows developers to build richer multimedia experiences, adding motion, audio, and storytelling, all powered by the same infrastructure behind OpenAI’s other models.
3. AgentKit, App SDK, ChatKit
The biggest highlight of the show was a trio of tools designed to simplify embedding AI into apps; it includes AgentKit, App SDK, and ChatKit. Where the AgentKit helps developers spin up AI agents in minutes, App SDK lets apps like Canva or Spotify integrate directly with ChatGPT, and ChatKit enables embedding ChatGPT-style chat features into third-party products.
4. Partnership with AMD
One of the biggest limiting factors in AI is computing power. To address that, OpenAI announced a multi-year partnership with AMD to expand its compute infrastructure. Even though OpenAI is already aggressively scaling, Altman and President Greg Brockman admitted compute remains a “critical bottleneck.”
5. Jony Ive joins the conversation on AI hardware design
In a rare public appearance, former Apple design head Jony Ive joined Altman to talk about OpenAI’s work on AI hardware. He emphasized making tools that help people feel less lonely and more content. Ive also remarked that the pace of AI progress is “extraordinary,” to the point where it’s tough to stay focused.
6. Scale, users, and future priorities
Altman shared some headline numbers: 800 million weekly users interacting with ChatGPT, 4 million developers, and an API that currently processes 8 billion tokens per minute. To underscore the company’s direction, he said OpenAI’s priority is growth and innovation, and not short-term profitability.
At DevDay 2025, OpenAI laid out not just new models and APIs, but a roadmap for how it wants AI to be built into everyday tools. The company is betting big on developers, infrastructure, and human-centric design, and it’s clear the next phase of AI won’t look like what came before.
