ChatGPT for business is now live

On November 10, OpenAI launched Businesses in ChatGPT in beta. Companies can now claim their business in ChatGPT and take control of the information about it.
In a dashboard called Business Hub, a verified business can update its details, add products with prices, and see how often ChatGPT mentions it and how many people click through to its website.
Why it matters: about 1.2 billion people use ChatGPT every week, and many ask it what to buy or which company to pick. Now businesses can make sure the facts about them are right.
US online shops and services can also add a Business Agent, a chat where customers ask about their products. It is clearly labelled and kept separate from ChatGPT’s own answers. Businesses can pay to promote it as an ad.
Can you use it? Any eligible business in a country where ChatGPT is available can claim its profile now. Business Agents are only for US online businesses so far.

AI helped prove that Signal’s encryption code is secure

On November 10, Google DeepMind said its AI agents helped mathematically prove key security promises in the code behind the Signal protocol, which protects private chats in apps like Signal and Google Messages.
People decided exactly what had to be proven. AI agents running on Gemini then wrote over six million lines of proof, which a computer checked step by step. Only about 1% of the code needed an extra human look.
DeepMind says it is the first time the actual code of such a widely used security protocol has been checked this deeply, with or without AI.
Why it matters: checking security this thoroughly used to take expert teams years. If AI makes it fast and cheap, more of the apps we rely on can be proven safe, not just tested.
Do you need to do anything? No. The work covered one version of Signal’s code library, not the whole app, and it did not find new bugs.

Google’s strongest Gemini model is now out

On November 10, Google released Gemini 4 Carbon to developers, businesses and consumers. It is Google’s strongest AI model, built for big, complex tasks.
Google says it is especially good at long coding projects, research, working through many documents at once and finding security holes in software.
Good to know: in the Gemini app, Carbon is only for subscribers to Google’s top plan, AI Ultra. For most everyday work, Google says its Argon model is still the right choice.
Why it matters: the biggest AI companies now release top models every few weeks, and each one can handle harder jobs than the last.

Ask AI what it says about you
More and more customers ask AI which company to choose. It is worth knowing what it tells them about you.
Try this before your next task:
What do you know about [business name] in [city]? What do we offer, what do our prices look like, and how do we compare with competitors? List your sources.
If anything is wrong or out of date, fix it at the source: your website, your Business Hub profile or the other listings the AI points to.
Do this every few months. It takes five minutes.
