OpenAI Wants ChatGPT to Be Your Future Operating System

Summary

At OpenAI’s Developer Day in San Francisco, CEO Sam Altman and the team unveiled a new apps SDK that lets third-party services run entirely inside ChatGPT’s chat window. The demo showed partners such as Spotify, Canva and Zillow operating interactively inside a single chat session — for example, designing posters in Canva, generating a pitch deck, and then querying Zillow to find houses in a suggested city.

OpenAI also showcased tools for building agent-based workflows (including AgentKit, a drag-and-drop builder), announced that Codex (their code-generation model) is leaving research preview and becoming generally available, and previewed merchant-facing features such as an “agentic commerce protocol” for in-chat checkout. The move is positioned as part of OpenAI’s strategy to make ChatGPT a central, chat-driven platform that keeps users inside a single conversational environment while competing for developer mind-share with Google, Anthropic, Amazon and open-source alternatives.

Key Points

OpenAI introduced an apps SDK to embed third-party apps directly inside ChatGPT conversations, with early demos from Spotify, Canva and Zillow.
Apps inside ChatGPT can be interactive and stateful: demos showed multi-step workflows that moved from design to market search to property filtering within one chat.
OpenAI plans monetisation tools for app developers, including an agentic commerce protocol to enable purchases from within ChatGPT.
The company launched AgentKit for building agents and made Codex generally available, adding developer-focused APIs, Slack code-editing, and analytics for monitoring usage.
This push is part of a broader strategy — including GPT-OSS, GPT-5 availability, and large chip/data-centre investments — to make OpenAI the hub for AI-driven apps and developer tooling, while battling rivals and open-source models.

Context and relevance

OpenAI is trying to redefine how we interact with software by combining web-like integrations and app experiences into a single chat interface. If successful, ChatGPT could become a primary platform — a conversational operating system — that routes many daily tasks through AI-driven apps and agents. That raises product opportunities for developers and enterprises, but also questions around platform lock-in, commerce rules, data flows, privacy and competition with other cloud and AI providers.

Why should I read this?

Quick and blunt: if you build apps, product-manage AI features, or keep an eye on where user attention is heading, this matters. OpenAI’s move could change how people access services — from searching to shopping — and shift where revenue and control sit. Read it to avoid being surprised when chat becomes the new home screen.
