ChatGPT becomes… a feed, an app, and a store
ChatGPT is becoming a feed, an app, and a store, as OpenAI in ~3 weeks launched Pulse (personalized morning briefing), Instant Checkout (purchase directly inside ChatGPT), Sora 2 (social video app), announced at Dev Day the Apps SDK + AgentKit and a 6 GW partnership with AMD, and finally released ChatGPT Atlas, its own AI browser for macOS. The message: from “chat interface” → “AI feed + apps + agents”.
ChatGPT Atlas
OpenAI launched ChatGPT Atlas, an AI-powered browser that brings ChatGPT to the center of browsing. Initially available for macOS, Atlas integrates memory, agent mode, and an “Ask ChatGPT” sidebar within a Chromium environment. In other words: browsing, search, and automation merge into a single workspace.
The most interesting features:
- Browser memories: ChatGPT remembers context from sites you visit (optional, you control it). You can ask “Find all the job listings I looked at last week and summarize the trends.”
- “Ask ChatGPT” sidebar: Ask questions about the pages you’re visiting without leaving them.
- Agent mode (Plus/Pro/Business only): ChatGPT can take real actions on your behalf - research topics, book appointments, automate tasks - while you browse.
Yes, browser memories sound a bit unsettling, but OpenAI insists that: you have full control and can view, archive, or delete them at any time from settings.
⚠️ Pro tip: if you use Atlas, make sure the “Improve the model for everyone” option is off· this setting is inherited in browser data.
As soon as Atlas launched, Google’s stock dropped 5%(~$150B). We won’t say it’s cooked, but Perplexity is definitely hurting: Atlas has ~80% of the Comet browser’s features, plus some new ones, and with the added benefit of 800M weekly active users that it can gradually convert into Atlas users.
Of course, Comet has a head start, and the browser-first players (The Browser Company, Opera) have something OpenAI is still learning: how a browser user thinks.
The big picture?
Atlas ties directly to the rise of GEO (Generative Engine Optimization). Browsing will no longer revolve around search results; it will revolve around AI agents that execute tasks for you in real time. So browsing becomes less SERP-centric and more task-centric, with agents performing work in-context. Content needs to be structured facts, clean entities, FAQ and actions that agents “understand.”
Atlas may be Mac-only and early stage. But the signal is clear: web browsing as we know it is changing, and we’re eagerly awaiting how Google will respond.
The 6th Dev Day
On October 6, OpenAI held its 6th Dev Day, where it announced an Apps SDK that turns ChatGPT into a universal interface for all your digital activities, new tools for agents (Agent Builder, AgentKit), Codex as generally available, and model updates (GPT-5 Pro API, Sora 2 with audio). At the same time, OpenAI struck a deal with AMD for 6 gigawatts of GPUs. The vision? ChatGPT as the new “home screen” of your digital life.
Apps SDK: ChatGPT as an app platform
OpenAI introduced Apps inside ChatGPT via the Apps SDK: real, context-aware experiences that “live” in the interface (course PiP, inline Canva/Zillow, shared context without re-prompting). It’s the second run after Custom GPTs-only with deeper integration.
AgentKit & Agent Builder
With AgentKit and a visual Agent Builder, OpenAI provides tools for auditable, production-grade agents and multi-agent flows without heavy backend work.
Codex (GA), GPT-5 Pro API, Sora 2 with audio
The platform makes Codex generally available, offers the GPT-5 Pro API for high-complexity industries, and the Sora 2 API with synchronized sound. (See the full list in the Dev Day notes.)
The compute problem & the AMD agreement (6 GW)
That same day, OpenAI announced a multi-year partnership with AMD to develop up to 6 gigawatts of GPU capacity, starting with 1 GW from H2 2026. The deal includes a warrant for up to 160M AMD shares (~10%), tied to milestones.
AI agents/app embeds scale only with massive compute. The agreement shows where cost/energy is heading-and why monetization (e.g., commerce/ads) is becoming a strategic priority.
Pulse, Instant Checkout, Sora 2
Pulse: your morning briefing from ChatGPT
ChatGPT Pulse sets up a once-a-day, curated feed with updates based on your conversations and connected apps (e.g., Calendar). The user curates what they care about by opening “cards” with quick summaries. It’s in preview for Pro (mobile) and is expanding. For media, this means a battle for the “first morning click.”
If Pulse becomes a default habit, it will require a content-by-intent strategy (topical, concise, with clear takeaways) instead of a generic newsletter blast.
Instant Checkout: ChatGPT as a store
With Instant Checkout, users in the US can buy within the conversation. Payments run through Stripe, starting with Etsy sellers, with >1M Shopify merchants “coming soon.” In parallel, the open Agentic Commerce Protocol enables retailers to integrate with minimal code.
A new acquisition surface: product discovery → recommendation → instant purchase without a context switch. It sets the stage for agentic funnels (e.g., agent-led cart building).
Sora 2: a social, remixable AI video app
Sora arrives as an iOS social app (invite-only, US/Canada), with cameos (bringing yourself into the video)and remix. It hit #1 on the App Store and surpassed 1M downloads in a few days-despite early conversations about moderation/IP.
Practically, it introduces a new form of brand storytelling with a UGC-like aesthetic and remix culture - along with new requirements around consent, IP, and brand safety.
Taken together, all of this shows how ChatGPT is gradually becoming a feed, an app, and a store that combines consumption, creation, and commerce.
OpenAI is redesigning the ecosystem around ChatGPT - a feed, an app, a store within a single interface.
For Marketing / SEO / E-commerce teams, this means GEO-ready content (structured facts, entities, FAQ), agentic funnels, and discipline in measurement and cost.
The next step isn’t “more posts,” but experiences that understand intent and execute actions.
