OpenAI’s latest event (October 6, 2025) wasn’t just a feature drop—it was a statement of intent. The company unveiled apps that run inside ChatGPT, a new Apps SDK for developers, AgentKit for building robust AI agents, major model updates (GPT-5 Pro, Sora 2, new voice), and a blockbuster AMD partnership to secure six gigawatts of GPU compute in the coming years. Together, these moves push ChatGPT from a chat interface into a full ecosystem—and give builders the horsepower to scale.
Key Takeaways
- Apps in ChatGPT + Apps SDK (preview): Build and run third-party apps directly inside ChatGPT; discovery via an app directory and app-like experiences in the chat window.
- AgentKit & tooling: Production-minded tools (AgentKit, new evals, RFT) to help developers create reliable, controllable agents.
- Model updates: GPT-5 Pro (flagship language model), Sora 2 (next-gen video), and a smaller, cheaper real-time voice model highlighted for API builders.
- Compute at scale: OpenAI × AMD multi-year partnership to deploy ~6 GW of GPU capacity starting 2026—diversifying beyond Nvidia.
- The strategy: Turn ChatGPT into a platform—complete with apps, commerce, and a growing developer base (4M builders; 800M+ weekly users).
Apps Inside ChatGPT: The Chat Window Becomes an Operating System
OpenAI introduced Apps in ChatGPT—mini applications that users can discover and run without leaving the chat. For developers, the Apps SDK (preview) provides primitives to build UI flows, connect third-party services, and ship app-like experiences that feel native to ChatGPT. This is a pivot from “bot” listings to first-class apps, complete with an app directory and forthcoming commerce to monetize.
Media outlets framed the shift bluntly: OpenAI wants ChatGPT to act like your next platform/OS, where productivity and services live in conversation. WIRED
Why this matters for SEO & growth teams: expect easier integrations (e.g., search, booking, analytics) to live in the chat, reducing friction from “copy-paste between tools.” For app makers, distribution via ChatGPT’s directory could become a meaningful channel. openai.com
AgentKit and New Dev Tooling: From Demos to Durable Agents
OpenAI’s AgentKit is aimed at teams graduating from prototypes to reliable, evaluatable agents. Alongside AgentKit, OpenAI highlighted new evals and reinforcement-from-feedback (RFT) tools to tune agent behavior, improve safety, and reduce regressions over time. The emphasis is operational: observability, testability, and iteration loops that suit production workloads.
Why it matters: The industry’s bottleneck has shifted from “can we generate?” to “can we trust and ship?” AgentKit + evals are designed to close that gap.
New Models: GPT-5 Pro, Sora 2, and Real-Time Voice
OpenAI spotlighted GPT-5 Pro for stronger reasoning and task reliability, Sora 2 for higher-fidelity video (with improved audio sync and soundscapes), and a smaller real-time voice model to power latency-sensitive experiences. While full technical cards are still emerging, early coverage underscores performance gains and API availability for builders. TechCrunch+1
OpenAI’s own product pages also called out fresh Sora work and product release updates leading into DevDay. For content teams and creative studios, Sora 2 hints at richer, multi-modal storytelling pipelines right inside existing workflows.
The App Store Moment: Discovery and Commerce
Alongside apps, OpenAI previewed a store-like experience: an app directory for discovery and commerce features (including in-chat checkout) so developers can sell digital goods or services directly within ChatGPT. This positions OpenAI as both a platform and a marketplace—potentially competing with incumbent app stores for user attention and spend. Business Insider
SEO angle: If your product solves a niche problem, ranking in ChatGPT’s directory could become as important as ranking on Google. Optimize your app listing, descriptions, and conversational flows for intent. Business Insider
Compute, Partnerships, and Scale: The AMD Shockwave
OpenAI announced a strategic partnership with AMD to deploy up to 6 GW worth of GPU compute from 2026 onward, with rights to purchase up to 10% of AMD via a warrant tied to milestones. The deal signals multi-vendor GPU strategy, likely easing constraints and lowering costs as OpenAI scales agents, apps, and media models. Major outlets noted the market jolt and the broader implications for the AI supply chain. AP News+1
Bottom line for builders: more capacity tends to mean cheaper, faster APIs and more generous rate limits over time—fuel for experimentation and growth.

- 6 GW GPU roadmap via AMD, starting 2026 deployments. AP News
What This Means for Teams (Actionable Takeaways)
- Start prototyping a ChatGPT app. If you have a SaaS, carve out one or two high-intent conversational journeys (onboarding, analytics Q&A, quick bookings) and test them using the Apps SDK. openai.com
- Design for distribution. Treat the app directory like a search surface; optimize your title, description, and conversation prompts for target keywords and tasks. Business Insider
- Plan an agent roadmap. Use AgentKit + evals to turn brittle scripts into robust agents with guardrails and measurable quality. openai.com
- Experiment with multi-modal. Kick the tires on Sora 2 and the voice model for richer onboarding, support, and content creation experiences. Digit+1
- Budget for scale. With the AMD partnership, expect API capacity to grow—keep a backlog of features you’d unlock with higher rate limits or lower costs. AP News
Conclusion: ChatGPT Is Becoming a Platform—Build for It
OpenAI’s 2025 event reframed ChatGPT as a platform rather than a product: apps you can build, agents you can trust, models that span text-to-video-to-voice, and the compute to run it all. For founders, marketers, and engineers, the opportunity is straightforward: ship inside ChatGPT, design for conversational UX, and ride the distribution wave as the directory and commerce features roll out. The companies that start now will own the early categories when the store doors fully open.
