If 2025 is the year of agents, 2026 will be the year of abundant software. I want to give you the no-BS summary of OpenAI Dev Day yesterday and why I hope every business professional who follows me is paying attention. Top takeaways: ⏩ Apps in ChatGPT— Apps from Canva, Coursera, Expedia, Booking.com, Figma, Spotify, Zillow, and more can now run inside ChatGPT. Devs can also get the Apps SDK and bring their own interactive tools into ChatGPT, complete with UI, context, and instant checkout. Commerce is getting prioritized. Crowd didn’t go nuts for this but brands might. If you have not yet realized the power of context engineering and connecting your AI systems with apps, I’m dropping a link to a guide I built below. ⏩ AgentKit — The closest we’ve seen to a real agent production workflow from OpenAI: agent builder, ChatKit, evals, connectors, guardrails checklist, all inside OpenAI’s dev platform. AgentKit takes on Make, Zapier, and n8n. In my opinion, enterprises need a bullpen (yes, like investment banking) of 30 Swiss Army knife employees that act as AI operators to build these out. I’d be looking for sharp operations or analyst minds and make them take an intro to python intensive, then have two energetic-for-AI engineers learn agent builder and upskill the 30. ⏩ Codex — Prepare for self-fixing software. Kind of. Upgraded with a Slack integration, SDK, and tools for code review and refactoring. Cisco cut code review time by 50% using Codex. The demos weren’t my favorite (they used it to control the lights on stage), but the much bigger hint was integrating Codex inside of apps with the SDK. Send this sentence to your engineers “Allie told me to tell you to review the Codex SDK announcement and consider embedding it into some test apps - it would allow our software to build more software and turn it into a self-evolving app.” And if you use slack “maybe we also add it into slack as a coworker so we can ping it requests like adding dark mode or voice input?” ⏩ New models — GPT-5 Pro is now in the API (big for legal, finance, and healthcare). GPT-realtime-mini is 70% cheaper (expect more voice-first interfaces). Sora-2 API is in preview for semi-controllable video + audio (big for design and product development). ⏩ Overall signal from the room — agents took the cake. Hints at a universal OpenAI login. Software will become more ephemeral. Strong signals the models will keep getting better. More interactive, adaptive, personalized AI. More interface changes to come. More user-to-user collaboration opportunities. More everything, probably. What questions do you have about the releases? 🎥 I also had 1-on-1 chats with Greg Brockman and Sam Altman - sharing more soon. Get the free guide here: https://lnkd.in/e2h_9gsr
