LATEST DEVELOPMENTS
OpenAI launched ChatGPT Wallet, which lets its AI agents, called dots, buy things for you. You approve every purchase with Face ID or a fingerprint, and the agent never sees your card number.
Details:
What it is: On November 13, OpenAI launched ChatGPT Wallet, built with Visa, Mastercard and American Express. It lets dots, OpenAI’s personal AI agents, finish a purchase for you.
How it works: You add a card once, then ask your dot to help you buy something. Before paying, you check the items, the total and the card, then approve with Face ID or a fingerprint. Every purchase needs its own approval.
Your card stays hidden: The card network creates a payment token, a stand-in for your card number, so neither the agent nor the store sees your real details. You still earn card rewards and can still dispute a charge.
Who gets it: For now, only ChatGPT Pro subscribers in the US who are 18 or older and have a US-issued card. The rollout is gradual, and OpenAI has not given a date for other plans or countries.
The catch: Some stores block AI agents, and Amazon is the biggest one. OpenAI published a guide to help stores accept agent orders, and it is not taking a cut of purchases at launch.
What’s next: OpenAI plans to add spending limits, rules by category or time period, and pre-approved purchases that the agent can finish with less input from you.
Takeaway: AI agents are moving from giving shopping advice to actually paying. For now you approve every purchase, but OpenAI is already planning ways to let agents buy with less input from you.
Google is rolling out Gemini 4 Hydrogen, its new fast and low-cost model, in Search worldwide. It’s the first Gemini 4 model available to all users for free, with smarter and more visual answers.
Details:
What happened: On November 12, Google brought Gemini 4 Hydrogen to Google Search globally for all users, in every language AI Mode supports. Until now, Gemini 4 models in Search (Argon and Carbon) were only for paying AI Pro and Ultra subscribers.
What Hydrogen is: It’s the fast, everyday model in the Gemini 4 family, adapted from the more powerful Gemini 4 Carbon. It replaces Gemini 3.8 Flash, and Google says it finishes tasks about 2.5x faster at its default setting.
Smarter searches: Search now handles multi-part questions, messy typos and very specific requests better. It also follows instructions more closely during back-and-forth conversations.
More links, more visuals: Improved “query fan-out” runs several searches at once across a question’s subtopics, so answers point to a wider range of websites. Responses also include more images, comparison tables, structured layouts and custom tools.
Beyond Search: Hydrogen is also rolling out in the Gemini app, Google AI Studio, the Gemini API, Gemini for business, Google Sheets and (for paid subscribers) Antigravity. Developers pay $1.50 per million input tokens and $7.50 per million output tokens.
The catch: Hydrogen is faster and cheaper, but it’s not smarter than Carbon or Argon on the hardest problems. It also costs developers twice as much per token as Gemini 3.8 Flash. Google is betting that speed and reliability make up for the price.
Takeaway: Billions of people now get a Gemini 4 model every time they use Google Search, with no subscription needed. Free search is getting a lot more AI-driven, and that puts pressure on ChatGPT and Perplexity.
OpenAI has disbanded its stand-alone robotics team and moved the researchers to other groups. It says general models like GPT-6 Astra can now run robots directly. No layoffs were reported.
Details:
What happened: OpenAI confirmed to Fortune on November 13 that its stand-alone robotics team no longer exists. The company says robotics is still central to its long-term plans.
Where people went: The robotics researchers joined the main research team under Chief Research Officer Mark Chen. The applied robotics and hardware staff moved to the Applied group under President Greg Brockman.
The reason: OpenAI says its general-purpose models, including GPT-6 Astra, can be used on robots directly. Its researchers had earlier expected progress to come from video models like Sora.
The numbers: In an Nvidia study, an agent powered by Astra scored 74.8% on a simulated robot-handling test. The best specialized robot models scored 51.0%.
Not the first time: OpenAI closed its first robotics team in 2020 and rebuilt one in 2024. It says it is still building its own humanoid robot, with a first public demo targeted for 2027.
Experts are split: A Carnegie Mellon professor said robots still need small models that run on the machine itself. An MIT robotics expert said robot companies keep an edge in real-world data from factory floors.
Takeaway: OpenAI is betting that one powerful AI model can do everything, from writing code to moving a robot’s arm. If it is right, robot makers may end up competing on hardware and data instead of on AI.
