Hosts: Chris Carolan, Nico Lafakis
September 29, 2026
Chris Carolan and Nico Lafakis watched OpenAI DevDay 2026 live and reacted: dots, GPT-6.1 Sol, Ultrafast, Codex in the cloud, the Agents API and an OpenAI Marketplace. Then Nico showed a skill that turns a slide deck into an interactive 3D walkthrough.
Moments from this episode
Key takeaways
OpenAI announced dots, always-on assistants inside ChatGPT that work on a standing responsibility in the background with their own cloud computer and browser, and check in when something needs approval. On stage OpenAI said they are available today to Pro, Business Premium and Enterprise users, starting with one dot; press reports the launch excludes the EEA, Switzerland and the UK. (03:10-07:37, 17:45-17:57)
The hosts started skeptical. A host said the people in the demos gave commands and walked away without checking the work, the hosts questioned the name and the call-your-dot demo, and a host said nothing shown was something they could not have done the week before. (05:12-05:38, 10:04-12:48, 17:00-17:05)
OpenAI said conversations with your dot do not count against your plan's usage, which drew the hosts' first real surprise. No printed source confirms that point yet. (17:52-18:28)
OpenAI announced GPT-6.1 Sol, which it says comes close to GPT-6 Astra at a much lower price (press lists $2 per million input tokens and $10 per million output tokens; sources conflict on naming and availability), an Ultrafast tier at up to eight times standard speed for six times the standard price, and a Pro 500 plan with 25 times the usage allowance of Plus. (20:02-22:25)
OpenAI announced a Decisions API in limited preview: a specialized version of its Luna model that picks from a fixed set of answers, so an app can route a request, classify an image or choose an agent's next step quickly. (22:36-23:14)
OpenAI said it has reached its goal of an AI research intern, and that as of July its models complete a third of day-long research tasks with no intervention. Both are stage claims; neither was found in print. (23:54-27:03)
OpenAI announced Codex running fully in the cloud, Codex Security Cloud, the Agents API in public beta and a preview of OpenAI Private Intelligence. The hosts were surprised Codex had not already been in the cloud, and a host said the Agents API was something to look at immediately. (28:31-31:05)
OpenAI announced Sign in with ChatGPT, so people can spend their own subscription inside other companies' apps, plus plugin extensions and an OpenAI Marketplace for enterprise buyers. A host wondered whether HubSpot agents could reach customers through it; nothing yet supports that. (44:51-48:36)
After the keynote a host asked "why didn't you lead with this?" and named Codex in the cloud and a marketplace for builders as what mattered most: it "would be nice to finally get paid for ideas." (53:45-55:43)
Nico Lafakis showed an information walkthrough: an AI read the slide deck from an AI mini bootcamp he ran with Chris, with "zero visual direction", and built an interactive 3D walkthrough. He is making it a skill and called it "my answer to people who think that decks are still relevant". (56:25-59:22)
