What's New This Week: A GPT Deadline, Two New Lessons and a First Look at Claude Duet
This week brought one deadline you should put in the diary, a handful of genuinely useful features for anyone running international or hybrid events, and a first look at where AI assistants are heading next. Here's what changed, what's new in Zoby OS, and what I'd actually do about it.
New in Zoby OS this week
Two new lessons:
- Moving a Custom GPT with Migrate to Plugin, in ChatGPT: Projects. If your team relies on a custom GPT, this is the one to read first (more on why below).
- Your Notebook, From Any Gemini Chat, and Decks You Steer, in the Gemini Notebook course. Ask your venue pack questions without leaving a Gemini chat, and shape a client deck before it gets built.
Lessons updated: What Happened to Custom GPTs, Projects, Not GPTs, Live Captions and Translation, Meet Notes That Become Actions, Copilot Explained, Plan Requirements and Microsoft 365 Context, An Event Planning Workspace, Notion Agent for Run Sheets and Supplier Trackers, and Labelling AI in Your Event Marketing.
The deadline: custom GPTs stop on 11 December
Every custom GPT is scheduled to stop running on 11 December 2026. OpenAI has now built a way out: in My GPTs, choose Migrate to plugin. Your instructions become a skill and your knowledge files come across with them. What doesn't come across is any custom action (the bit that talked to your booking system or CRM), the model you picked and your sharing settings, and the new plugin starts private, so your colleagues lose access until you share it again.
My view: press the button now, while you can still open the old GPT and the new plugin side by side and check nothing got lost. Six weeks is plenty of time, until it isn't.
Claude Duet: a first look (US only for now)
Anthropic has announced Claude Duet, a new app where Claude works as a proactive assistant. Rather than waiting for you to ask, it checks in on things that need attention, handles tasks you hand it and keeps working while you're away. It runs on iPhone, Android and claude.ai.
The bit I like is the guard rails. Duet can read and draft on its own, but before it sends a message, makes a payment, signs a document or deletes anything, it shows you exactly what it's about to do and waits for your yes. Some things, like moving money between accounts, are off-limits even if you approve them.
The catch for us: it isn't in the UK yet. It's a research preview with a waitlist, starting with Pro and Max subscribers in the US. Anthropic says it is starting there, so more countries should follow, but there is no UK date. I'll tell you the moment it lands here, and there will be a Zoby OS lesson on using it safely for events admin when it does. In the meantime, the Safe AI Agents course covers exactly the habits you'll want.
ChatGPT: lock the chats a client shouldn't see
ChatGPT is rolling out locked chats on Free, Go, Plus and Pro. A locked chat disappears from your history, pins and search, and opens with a PIN or Face ID. Handy if you ever share your screen in a client meeting and don't want last week's rival proposal popping up. Two things to know: it hides chats rather than encrypting them, and if you reset the PIN, everything you'd locked is deleted.
Google: translation, notebooks and recaps
- Meet speech translation now covers 63 languages and detects the language automatically. It's on paid Workspace and Google AI plans, capped at 90 minutes a meeting on most plans. Brilliant for a supplier briefing with an overseas partner. For a keynote where every word matters, still book an interpreter.
- Gemini Notebook from any Gemini chat. Type @Gemini Notebook and ask your notebook questions without opening it. It's off by default in the EU, but on for UK accounts.
- Steer the deck before it's built. Gemini Notebook now lets you review a slide deck's outline and give feedback before it generates. Always take that step for anything a client will see.
- Meeting recaps in Google Chat. On Business Standard, Business Plus and Enterprise plans, if Take notes for me is on, a meeting linked to a Chat space gets a recap posted there automatically: decisions, actions with owners, and links to the notes and recording.
- Gemini apps to Google Sites. Anything interactive you've built in the Gemini app can now go to a private Google Sites draft in one click, ready to edit and publish.
Microsoft and Notion: how you pay is changing
Microsoft 365 Copilot can be bought without a Microsoft 365 base subscription from 1 December, at the same price as today. Useful if part of your team runs on something else.
Notion has moved all of its AI onto a single credit system, with a new Auto setting that picks the model for each task and, Notion says, makes credits go about ten times further. Its agents now have their own browser too, and can work on a task for up to 24 hours. That's powerful, which is exactly why you should be strict about which databases each agent can reach.
The rules
The UK's advertising regulators (the ASA, CAP and the CMA) have published a new edition of their Influencers' guide. It says AI-generated content has to follow the same ad rules, and it counts a virtual, AI-made persona as an influencer. If anyone, real or AI, is promoting your event as an ad, it still has to be obvious that it's an ad.
In Europe, EU governments have agreed their position on simplifying data and cookie rules, which could mean fewer cookie banners in future. That's a proposal, not a change, so keep your consent setup exactly as it is for now. And the ICO's call for evidence on AI agents closes on 20 November.
As ever, menus move and plans change, so check the provider's own page on the day. If something here has changed how you work, I'd love to hear about it.
