Welcome, humans.

OpenAI DevDay 2026 starts today. We’re watching it with you.

OpenAI is about to spend a keynote showing us what it thinks developers should build next. New models? New agents? New APIs? A demo that makes Grant start yelling at the screen? All very possible.

So instead of waiting for the post-event summaries, Grant Harvey and Corey Noles are going LIVE for a DevDay watch party and reacting to the keynote as it happens.

When to join

Right now! we just went live.

OpenAI’s keynote starts at 10:00 AM PT / 12:00 PM CT / 1:00 PM ET and features Sam Altman, Romain Huet, Tejal Patwardhan, and Holly Li.

We’ll keep OpenAI’s stream up, react in real time, and translate the demos into normal-person English while they’re still happening.

What we’re watching for

• New models: anything that changes the capability, speed, price, or usefulness of what developers can build (this is unlikely, per WSJ, but idk).

• Agents: especially tools that can do work across apps, APIs, browsers, or computers instead of only answering prompts (this should be called “dot”).

• Developer tools: APIs, SDKs, coding workflows, infrastructure, and anything that makes AI easier to ship inside real products.

• The demo-vs-reality gap: what actually looks useful versus what merely looks great on a keynote stage.

• The weird surprise: because there is almost always one announcement nobody had on the bingo card.

The point: by the end, you should know what OpenAI actually announced, what changed, and which parts are worth paying attention to after the livestream ends.

And yes, if you miss the beginning, the recording will live at the same link.

📚 Want the official source open too?

Yep, there are a few official OpenAI pages worth having open next to the watch party:

• OpenAI DevDay 2026: the main event page, full agenda, keynote timing, and event details.

• Official OpenAI YouTube livestream: the actual keynote stream from OpenAI. This is the direct link to use if you want the raw event alongside our watch party.

• DevDay keynote community post: OpenAI’s developer-community announcement for the stream.

• DevDay Exchange: OpenAI’s page for the follow-on developer events in Bengaluru, Tokyo, Seoul, Berlin, Paris, London, São Paulo, and Mexico City.

And of course, our watch party is right here if you want Grant + Corey commentary layered on top.

👀 What’s already happening before Sam hits the stage

OpenAI is not exactly setting expectations low. The official YouTube description says Sam Altman, Romain Huet, Tejal Patwardhan, and Holly Li will unveil 20+ launches, debut new capabilities, and demo new breakthroughs for the first time.

• The day is much bigger than the keynote: OpenAI Developers posted an agenda with five stages and 22 breakout sessions running after the keynote. One Codex session teases an internal agent that spent 1,000+ hours keeping builds and tests passing.

• Sam’s pre-show teaser: OpenAI has “built some great stuff for you.” That is the entire product preview. Very helpful for the bingo cards, Sam.

• OpenAI’s morning message was even more specific: “10am PT, on the dot.” Subtle!

• Meanwhile, the subscription drama is already live: Tibo says Pro $200 is reopening, but its usage math now works out to about half the API-dollar spend of the old Pro $200 plan. He also says DevDay will add still-unrevealed subscription features that do not draw on usage.

So the thing to watch is not merely “how many things did OpenAI launch?” It is which launches actually change what you can do, what they cost, and whether those new subscription perks make the new limits feel any less painful.

🎥 While you wait, catch up on the chaos

GPT-6 Sol vs. Claude Opus 5.5, Round 2

We stopped asking the models trivia questions and made them build things: a black-hole simulator, a Blender world, harder games, and increasingly cursed versions of Cat Doom.

Why AI infrastructure is more than “more GPUs”

CoreWeave EVP Chen Goldberg joined Corey to explain why modern AI infrastructure behaves less like a pile of chips and more like one enormous computer.

One more before you go:

If OpenAI drops anything truly ridiculous today, there is a very good chance Grant and Corey will try to break it live. For science, obviously.
