ChatGPT Work vs Gemini Spark: Task Agent or Always-On Agent?
The two biggest AI labs shipped their “agent that does your work” within eight days of each other — and they made opposite bets. ChatGPT Work, launched July 9, 2026, is a task agent: you hand it an outcome, it plans, works for hours across your connected apps, and ships a finished deliverable. Gemini Spark, which landed on macOS in beta on July 1 after its I/O introduction in May, is an always-on agent: a 24/7 assistant that lives in your Google world, tracks topics in real time, and works with the files on your machine.
Different shapes, different gates, very different bills. Here’s how they actually compare.
The shape of the agent: kick-off vs always-on
ChatGPT Work is a mode you invoke. Describe the outcome (“audit these five contracts and build a summary sheet”), and the GPT-5.6-powered agent gathers context from your connected apps and files, shows you its plan, then works independently for hours — with check-ins and action approvals along the way. The output is finished spreadsheets, slides, documents, or interactive web apps, not a chat reply.
Gemini Spark doesn’t wait for a kickoff. Google pitches it as a 24/7 agentic assistant that runs continuously: it integrates with Gmail, works with local files on your Mac — sorting, organizing, turning them into Workspace docs — and does real-time topic tracking for things like stock moves, scores, and breaking news. Google says cross-device assignments are coming: ask on your phone, have Spark work through files on your Mac.
If your mental model is “give the AI a project,” that’s Work. If it’s “have an assistant that’s always running in the background,” that’s closer to Spark — with the caveat that Spark’s always-on behavior today is strongest inside Google’s own apps.
Integrations: 1,400 connectors vs Google’s home turf
ChatGPT Work launches with a directory of 1,400+ connectable apps you can @-mention — HubSpot, Gong, Slack, project management, email. Notably, its Gmail connector can actually send email (web-only, no attachments, not available in the EU/UK, per-message approval required), while its Google Calendar connector is read-only.
Spark’s integration story is depth over breadth: it sits natively on Gmail, Google Tasks, and Keep — the default apps of over a billion people — and its third-party list at launch is short and consumer-flavored: Canva, Dropbox, Instacart, OpenTable, and Zillow Rentals. The escape hatch is MCP support, which lets you wire in anything with an MCP server, but that’s a build-it-yourself path rather than a directory of 1,400 ready connectors.
The irony is hard to miss: OpenAI’s agent currently has a more permissive relationship with Gmail sending than it does with Google Calendar, while Google’s own agent has the deepest Gmail integration of anyone — gated behind its most expensive tier.
Pricing and availability: metered allowance vs the Ultra gate
ChatGPT Work has no separate price — it’s usage-metered against your plan’s allowance, the same structure Codex uses, with variable consumption by task complexity and no published per-task rate. It rolled out July 9 to Pro, Enterprise, and Edu on web and mobile (all plans on the new macOS desktop app), with Plus and Business following within days. That’s a broad, multi-platform rollout out of the gate.
Gemini Spark is gated hard. The Mac beta is US-only and requires Google AI Ultra, Google’s most expensive consumer tier — now starting at $99.99/month after Google restructured its subscriptions at I/O, with a $200/month top tier for the heaviest users. No Windows, no mobile assignment flow yet, no availability outside the US.
So the comparison in July 2026 is a bit asymmetric: ChatGPT Work is something most paid ChatGPT users will have within a week; Spark is something a US Mac owner paying about $100/month can beta test.
The third option: an assistant that acts on triggers
Strip the branding away and both products leave the same gap. ChatGPT Work needs you to start every task. Spark runs 24/7 — but inside Google’s ecosystem, on one platform, in one country, at Google’s top price. Neither will watch your CRM and fire a workflow when a deal closes, or send the follow-up email itself on whatever inbox your company actually uses.
Carly is built for exactly that lane: an AI executive assistant that acts on triggers — incoming email, calendar events, form submissions, CRM changes, schedules — 24/7 in the cloud, no desktop app, no beta waitlist. Setup is a conversation: describe the workflow in plain English and Carly builds it, no code. It connects to 200+ tools natively plus any other tool via your own API key, and it actually sends email on both Gmail and Outlook. AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited.

Frequently Asked Questions
What’s the main difference between ChatGPT Work and Gemini Spark?
The agent model. ChatGPT Work is task-based — you assign an outcome and it works for hours until the deliverable is done. Gemini Spark is an always-on assistant that runs 24/7, tracking topics and organizing files continuously, mostly inside Google’s ecosystem. Work is broadly available across paid ChatGPT plans; Spark is a US-only macOS beta for Google AI Ultra subscribers.
Is Gemini Spark worth $99.99 a month?
Spark is included with Google AI Ultra (from $99.99/month), so the question is whether you want Ultra’s whole bundle — roughly 5x Pro usage limits, 20 TB storage on the higher tier, and Spark. If your life runs on Gmail and a Mac and you already wanted Ultra’s limits, Spark is a strong bonus. As a standalone reason to pay $100/month for a US-only beta, it’s early.
Which has more integrations, ChatGPT Work or Gemini Spark?
ChatGPT Work by a wide margin on count: 1,400+ apps in its connector directory versus Spark’s Google apps plus five named third parties (Canva, Dropbox, Instacart, OpenTable, Zillow Rentals). Spark counters with MCP support for custom connections and deeper native access to Gmail and Workspace than any outside agent gets.
Can either one run workflows automatically when something happens?
Not in the trigger sense. ChatGPT Work executes tasks you assign. Spark runs continuously but does its own ambient work (tracking, organizing) rather than firing your defined workflows on events. If you need “when X happens, do Y and send the email,” that’s an assistant like Carly, which runs trigger-based workflows around the clock.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
