Please enjoy the complimentary vision of your future rent.* OpenAI DevDay has the spiritual energy of a landlord inviting everyone downstairs to applaud the new elevator. The elevator is impressive. It may genuinely change your life. You are still paying rent, and the man operating the spotlight owns the building. That is my aggressively overcaffeinated reading of the occasion. The official version is more restrained: [OpenAI’s 2026 developer gathering](https://devday.openai.com/?ref=siliconsnark.com) is scheduled for September 29 at Fort Mason in San Francisco, with a 10 a.m. Pacific keynote featuring Sam Altman, technical sessions, workshops, and a reception. Invited attendees pay $650; limited scholarships are available, and the keynote livestream is free. Six hundred and fifty dollars to discuss the future of building on someone else’s infrastructure. Honestly, the housing metaphor is doing its own push-ups. *This is an opinion column about DevDay’s platform politics, based on the confirmed event information and previously announced tools, rather than a recap of the 2026 keynote.* Here is the hot take: the most consequential product at a developer conference is permission to imagine your entire business inside the host’s business. The demos make that arrangement feel like liberation. Sometimes it is. Sometimes you have simply automated the process of becoming a tenant. ## The revolution will have a billing administrator To see the strategic shape, look at [OpenAI’s DevDay 2025 lineup](https://openai.com/devday/?ref=siliconsnark.com). It included apps inside ChatGPT, an Apps SDK preview, AgentKit, and Codex reaching general availability with additions including an SDK and enterprise controls. Those are useful building blocks. They also describe an unusually ambitious position in the software economy: help create the software, help run its agents, and offer a place where customers can encounter it. My interpretation is that OpenAI would quite reasonably like to be involved in as many of those moments as possible. Your startup gets an origin story. The platform gets several opportunities to send an invoice. Everybody wins, subject to the fascinating question of how much. This is where the ceremonial vocabulary gets magnificent. A founder becomes a “builder.” A vendor becomes an “ecosystem.” Depending on another company’s product decisions becomes “moving at the speed of innovation.” Put that sentence on a hotel ballroom screen and somebody will fund it. I used to do predictive analytics. Even I find this much euphemism statistically horny. ## Your moat has a guest Wi-Fi password Imagine a fictional startup called WorkflowDaddy. It turns customer emails into useful actions, has a handsome dashboard, and raised enough money to employ a person whose entire job is saying “category-defining.” WorkflowDaddy uses a model supplier to interpret requests. It builds around that supplier’s tools. It hopes to reach customers through that supplier’s interface. Then its pitch deck describes the resulting arrangement as a proprietary moat. Sweetheart, that is a pool in an Airbnb. This does not mean WorkflowDaddy is doomed. Owning a difficult customer relationship, understanding a particular industry, and doing the miserable integration work can create lasting value. A dental practice does not care how spiritually independent your architecture is. It wants the appointment system to stop eating Thursdays. But if the whole business is “we put a nicer button on a capability the platform already sells,” every product announcement becomes a weather alert. Better underlying technology can simultaneously improve your service and make your distinctive feature less distinctive. That is the peculiar emotional cocktail of DevDay: the supplier can make your week and complicate your business plan in the same sentence. Applause, followed by a discreet message to the cofounder: “Can we talk?” ## I regret to inform you that the tools can be good The inconvenient part of this roast is that useful technology ruins a beautifully simple grudge. We have already given [Codex its flowers](https://www.siliconsnark.com/openai-codex-deserves-flowers-preferably-delivered-by-a-passing-build-agent/). Helping people build software is a substantial achievement. Removing tedious work can let a small team attempt something it otherwise could not afford. There is no intellectual prize for pretending a working tool is useless because its supplier also has a revenue department. In fact, usefulness makes the platform question more serious. Nobody needs a strategy meeting about becoming dependent on software they never open. The attachment forms because the product saves time. Then it accumulates workflows. Then the workflows accumulate assumptions. Eventually, switching suppliers means discovering how many tiny business decisions were secretly architectural decisions wearing casual Friday clothes. The sensible response is to count those costs while enjoying the benefits. The conference response is to play louder music. ## The autonomous future needs you to click Approve There is another magnificent tension in the agent pitch. We want machines to do more work on their own, while also wanting them to stop before doing anything spectacularly stupid. Both desires are reasonable. Combining them is engineering. Describing the combination as effortless is marketing. As our guide to [agents that operate your computer](https://www.siliconsnark.com/computer-use-agents-explained-why-openai-anthropic-and-perplexity-want-to-operate-your-laptop/) explains, the challenge extends beyond getting software to click. It includes handling changing interfaces, recovering from mistakes, and deciding when a human needs to intervene. My imaginary ideal DevDay demo would therefore begin with a task going wrong. The agent notices. It stops. It explains the problem clearly. It preserves the work. Nobody accidentally buys 400 ergonomic chairs. I would stand up and clap like a seal with procurement authority. Instead, the cultural temptation is to celebrate how many things a machine can start. Starting things is easy to romanticize. Finishing them correctly, within a budget, without making the office manager develop a facial twitch: that is where the value lives. We should demand more spectacle around competent restraint. Give the rollback button a smoke machine. ## Please show the margin before the standing ovation Our recurring question about [whether AI agents actually make money](https://www.siliconsnark.com/do-ai-agents-actually-make-money-in-2026-or-is-it-just-mac-minis-and-vibes/) remains an excellent antidote to keynote intoxication. For a builder, the useful calculation is painfully ordinary: what does a successfully completed task cost after retries, human review, support, and the occasional afternoon spent diagnosing something that worked beautifully on Tuesday? A cheaper component helps. A faster model helps. Neither automatically answers the business question. My preferred conference slide would show a customer problem, the old cost, the new cost, the failure rate, and how easily the customer can leave. Five numbers and an exit. Venture capital’s least erotic PowerPoint. That would tell us more than another declaration that everybody can build anything. If everybody can build anything, the scarce things become customers, trust, distribution, and the ability to keep a service working after its founder goes to sleep. The landlord understands scarcity. That is why the landlord owns the building. ## Enjoy the elevator. Read the lease. My absurd proposal is to rename the whole occasion Tenant Appreciation Day. Keep the workshops. Keep the demos. Keep the genuinely talented engineers explaining genuinely useful work. Replace the grandiose future-of-humanity soundtrack with a brutally informative session called “What Happens to Your Margins If We Change Something?” OpenAI does not need to be malicious for developers to need bargaining power. Good tools and concentrated dependence can grow together. A platform can create enormous opportunity while arranging to collect a meaningful share of it. So yes, build the thing. Use the excellent tools. Make something people want enough to pay for. Just have a better answer to “What do you own?” than “We have a very strong relationship with the API.” DevDay’s hottest demo may be the software. Its hottest business model is being the place where everyone else builds theirs. Please collect your lanyard. The elevator now reasons.
