Developer cut: how always-on agents actually work — cloud VMs with browsers, 4,000+ (Dots) and 6,000+ (Duet) app connectors, polling loops, read-only background research vs permissioned actions, and the approval gates that matter.

Your AI just started working while you sleep — and you didn't ask it to.
For years, every AI assistant worked the same way: you type, it answers, it waits. In five weeks in autumn 2026, that changed. OpenAI launched Dots on 29 September, Anthropic opened the Claude Duet research preview on 21 October, and Ant Group unveiled Lingguang 2.0 on 29 October. Three launches, one idea: an AI that does not wait for your prompt. It keeps a list of your goals and works through it while your laptop is off.
From chatbot to colleague
The old loop was prompt, response, next prompt. The new loop is watch, think, act, check, ask. The agent lives on its own computer in the cloud, with its own browser, so it keeps working after you close the app. It connects to the apps where your work piles up — email, calendar, Slack, Stripe, shops — and it remembers your preferences, your past conversations and your ongoing work, so you never have to repeat yourself.
Every morning, Anthropic's Duet sends a short brief of what matters across your connected accounts. During the day it checks those accounts every few hours and messages you only when something needs a decision. OpenAI's Dots work the same way: a dot keeps working when the conversation stops, and its background research looks through your connected apps for ways to help — noticing, for example, that a travel plan changed.
The three agents, side by side
OpenAI Dots live inside ChatGPT and run on GPT-6 Astra. Each dot has its own cloud computer and browser and connects to more than 4,000 apps. The first dot is included at no extra cost on Pro and Business Premium plans in eligible markets; Pro costs $100, $200 or $500 a month in the US. At launch, Pro access excludes the European Economic Area, the UK and Switzerland, and Enterprise workspaces get Dots only as a beta an admin switches on — off by default.
Anthropic Claude Duet is a separate app on iPhone, Android and the web, running on Claude Opus 5.5. It is in research preview for US Pro and Max subscribers on a waitlist; Team and Enterprise plans are not included yet. Duet claims more than 6,000 connectors, naming Gmail, Slack, Stripe, QuickBooks, Gusto, HubSpot, Docusign, Canva, Shopify and LinkedIn.
Ant Group's Lingguang 2.0 is the consumer version of the same idea: book a flight and it tracks the price for a day, alerting you if the fare drops; it also flags subscriptions you pay for but never use.
The voice that talks like a person
Block's Dessa, unveiled 23 October 2026, shows where the voice of these agents is heading. Dessa is a full-duplex speech-to-speech model trained from scratch on nothing but recorded human conversation — no text, no pretrained models. It listens and talks at the same time, laughs, sighs and hears sarcasm. Block says it learned language from hundreds of times fewer words than large language models and runs locally on a MacBook Pro M4 Max or better. Be clear-eyed about this one: Dessa is research, not a product you can buy. There is a waitlist and early access for a small group of safety researchers, no published benchmarks, and the demos are selected by Block itself.
The guardrails — and the holes in them
The good news first. Both Dots and Duet ask before anything irreversible. Before Duet emails or messages anyone, spends money, signs a document or deletes anything, it shows you its plan and waits for your yes. Two actions are barred outright, approval or not: trading securities and moving money between accounts. Dots' background research is read-only by design: it cannot send messages, change app content or control the browser until it switches into a real task with permission checks. Dots also lets you write Custom Rules for what it may do alone, what needs approval and what is blocked, and some safety checks cannot be switched off. The model never directly sees your passwords or sign-in tokens, and a dedicated classifier refuses requests to share card numbers and government ID numbers.
Now the holes, stated honestly. Duet checks every few hours, not every minute — Anthropic itself says something urgent can arrive between checks, and that Duet "still might misread a thread or miscalibrate what is urgent." Background work eats your usage limits: Duet counts against your existing plan, and Dots' deeper work draws on a plan allowance. And disconnecting an app from Dots does not erase what it already learned; only resetting the dot deletes its conversations, saved memories and scheduled tasks.
Five tasks to delegate this week
- A morning brief of your inbox and calendar.
- Tracking a price or a delivery.
- Drafting replies that you approve before sending.
- Chasing an unpaid invoice with a polite reminder.
- Auditing subscriptions you forgot you pay for.
Five rules that keep you in charge
- Never let an agent spend, send or sign alone.
- Keep approval ON for money and messages.
- Start read-only: let it watch and draft before it acts.
- Try disconnecting once, and check what it kept.
- Watch your usage cap — an agent that works all night spends your allowance all night.
The real shift
Your job with AI just changed. It used to be asking good questions. Now it is setting good goals and good limits. The people who learn to manage an agent now — to write down the three jobs they would hand over tomorrow, and the one line they would never let it cross — will have a head start on everyone else. That list is your first agent instruction.
Paragon AI MAG tracks revolutionary AI research and explains what it means — before it changes everything.
