Claude Duet (Anthropic, research preview since Oct 21, 2026) and Grok Bot (xAI, early beta since Aug 2026) run on their own cloud computer and keep working after you close the app. Both ask for approval before they act. Neither is sold as a separate product. Each is included in a consumer subscription, so the price is the price of the plan that unlocks it.
Short answer
- Claude Duet has no price of its own. It is included in Claude Pro (20,00 $US a month) and Claude Max (100,00 $US or 200,00 $US), by waitlist and for US accounts first.
- Grok Bot is included in Grok Premium (30,00 $US a month), Super (100,00 $US) and Ultra (200,00 $US), and in eligible Teams and Enterprise plans. Super and Ultra raise the weekly Grok Bot allowance to 3.5× and 12× the Premium level.
- Neither vendor publishes an absolute usage cap. Claude Duet draws on the same limits as the rest of Claude, and Grok Bot's allowance is stated only as multiples of a base tier.
- Lowest entry price: Claude Pro at 20,00 $US a month for Claude Duet, Grok Premium at 30,00 $US a month for Grok Bot.
Claude Duet and Grok Bot side by side
Values come from Anthropic's announcement (Oct 21, 2026) and xAI's Grok Bot and pricing pages (read Oct 22, 2026). Where the two xAI pages disagree, the row says so.
| Aspect | Claude Duet | Grok Bot |
|---|---|---|
| Maker | Anthropic | xAI |
| Status | Research preview, announced Oct 21, 2026 | Early beta, announced Aug 11, 2026 (per press coverage) |
| Where it runs | Standalone iOS and Android app, and claude.ai | Desktop and iOS |
| Access | Waitlist. Pro and Max users in the US first | Included in eligible Premium, Super, Ultra, Teams and Enterprise plans |
| Plans that include it | Pro 20,00 $US · Max 5x 100,00 $US · Max 20x 200,00 $US | Premium 30,00 $US · Super 100,00 $US · Ultra 200,00 $US |
| Usage limits | Shares the plan's Claude usage limits. Background checks count toward them | Weekly Grok Bot allowance. Super is 3.5× and Ultra 12× the Premium level |
| Model | Built around Claude Opus 5.5 | Not named on xAI's Grok Bot page |
| Cloud computer | Virtual machine with its own browser. Your phone or laptop can be off | A cloud computer shared by all Bots on the account. Signs in to your apps and websites |

| Limits stated by the vendor | May misread a thread. Personal errands are weaker than work tasks. The browser cannot be viewed yet. Separate from the main Claude app | None listed on the Grok Bot page |
Claude Duet: price and usage limits
Anthropic describes Claude Duet as a proactive agent for professionals and small business owners. It sends a short brief each morning, checks connected accounts every few hours, and works on assigned tasks in a virtual machine, so your phone or laptop does not need to stay on. During the research preview it is included in Pro and Max at no extra charge and uses the same usage limits as the rest of Claude.
Plans that include Claude Duet
| Plan | Monthly price | Source |
|---|---|---|
| Claude Pro | 20,00 $US/mo, or 16,67 $US/mo on annual billing | Official page |
| Claude Max 5x | 100,00 $US/mo | Official page |
| Claude Max 20x | 200,00 $US/mo | Official page |
Anthropic says the background checks count toward the plan's limits, which is why Claude Duet checks every few hours instead of continuously. Larger jobs, such as a financial model or a slide deck, take more model turns and use more of the allowance than a typical conversation. No absolute number of Claude Duet tasks or tokens is published, so the practical limit depends on how much background work you assign.
Access is by waitlist and starts with Pro and Max users in the US. The announcement covers those accounts only and gives no date for other plans or regions.
Claude Duet is designed around Claude Opus 5.5. Anthropic's API lists Opus 5.5 at 4,00 $US input and 20,00 $US output per 1M tokens, with cache reads at 0,20 $US. That is below Claude Opus 5 at 5,00 $US and 25,00 $US.
Grok Bot: price and usage limits
xAI describes Grok Bot as AI teammates that sign in to your tools, use them the way you would and return finished work. Bots run on a cloud computer that all Bots on the account share, several Bots can work in parallel, and a workflow you demonstrate once can be saved as a routine that runs on a schedule.
Plans that include Grok Bot
| Plan | Monthly price | Grok Bot usage | What changes | Source |
|---|---|---|---|---|
| Grok Premium | 30,00 $US/mo | Weekly allowance (1×) | Grok Bot with its own computer, sign-in to your tools and scheduled routines | Official page |
| Grok Super | 100,00 $US/mo | 3.5× Premium | Priority model access at peak times | Official page |
| Grok Ultra | 200,00 $US/mo | 12× Premium | Earliest access to all products and models | Official page |
xAI states usage as multiples, not absolute numbers. The Grok Bot page gives Super as 3.5× and Ultra as 12× Premium. The pricing page uses Plus as the base instead: Premium at 4× and Super at 15× Plus, which works out to 3.75× between Premium and Super. The two pages do not share a base, and Ultra appears only on the Grok Bot page.
Grok Bot is also included in eligible Teams and Enterprise plans. The pricing page lists a Plus tier at 8,00 $US a month, but shows Grok Bot from Premium upward.
The Grok Bot page does not name the model behind it, and the pricing page says Premium includes the latest Grok models. The newest Grok model in this site's catalog is Grok 4.7, released Sep 21, 2026 and listed at 2,00 $US input and 6,00 $US output per 1M tokens on xAI's API.
What the plan fee buys at API list prices
A plan fee can be converted into tokens at a model's API price. This is a unit conversion and not an allowance, because neither vendor publishes how many tokens a plan includes. The table uses the blended price this site uses everywhere (75% input, 25% output) and ignores cache discounts, which lower the cost of agent loops that reread the same context.
| Plan | Monthly fee | Reference model | Blended price per 1M | Tokens at list price |
|---|---|---|---|---|
| Claude Pro | 20,00 $US | Claude Opus 5.5 | 8,00 $US | 2.5M |
| Claude Max 5x | 100,00 $US | Claude Opus 5.5 | 8,00 $US | 12.5M |
| Claude Max 20x | 200,00 $US | Claude Opus 5.5 | 8,00 $US | 25M |
| Grok Premium | 30,00 $US | Grok 4.7 | 3,00 $US | 10M |
| Grok Super | 100,00 $US | Grok 4.7 | 3,00 $US | 33.33M |
| Grok Ultra | 200,00 $US | Grok 4.7 | 3,00 $US | 66.67M |
Read the last column as the monthly volume at which API spend on that model would equal the fee. The Claude plans also cover chat and Claude Code, so only part of the fee is attributable to Claude Duet. Test your own volume with the subscription vs API calculator and the cost calculator.
Why background work changes the math
A chat plan is used when you type. These agents also use it when you do not. Claude Duet checks connected accounts every few hours, and Anthropic says checking continuously would use up plan limits much faster. Grok Bot runs routines on a schedule and can run several Bots at once, which xAI describes as working 24/7.
How much of an allowance is used depends on how many connected apps or scheduled routines are active and how large each task is. Anthropic names financial models and decks as heavier jobs. xAI's tiers differ mainly in the weekly Grok Bot allowance, so the number of Bots you keep busy is the practical reason to move up.
Before paying for a higher tier, check what the agent does in the background. List the active routines and connected accounts. Claude Duet lets you set what it reports and how often.
Other always-on agents
Three other consumer agents follow the same design: a cloud computer that keeps working after you leave. All three were announced before Claude Duet. Always-on AI agents explained compares all five.
| Agent | Maker | Announced | Where it is included |
|---|---|---|---|
| ChatGPT dots | OpenAI | Sep 29, 2026 | ChatGPT Pro from 100,00 $US a month and Business Premium, in eligible markets |
| Meta Muse | Meta | Sep 8, 2026 | Free with a weekly limit, plus Power at 20,00 $US and Maximum at 100,00 $US a month, in the US on iOS, Android, muse.ai and WhatsApp |
| Gemini Spark | May 19, 2026 | Google AI Pro (19,99 $US a month) and AI Ultra, outside the EEA, Nigeria, Switzerland and the UK |
Which one fits
- You are on Claude Pro or Max in the US and want an assistant tied to your Claude memory, skills and connectors: Claude Duet adds no charge during the preview and runs inside your current limits.
- You want several agents working in parallel, routines taught by demonstration, or a desktop app: Grok Bot, from 30,00 $US a month.
- You are comparing price alone: Claude Pro at 20,00 $US is the lower entry point, but Claude Duet is waitlisted and US-first. Grok Premium at 30,00 $US includes Grok Bot, and xAI's page offers it for download with the plan.
