Gemini CLI / Antigravity in Continuum

Same Google-side agent quality when you pick it. Continuum adds peers, panes, and a bill you can actually read.

Google's coding-agent lane moved in 2026. Gemini CLI stopped serving free, Google AI Pro, and Ultra users on 18 June 2026; the repository stays Apache-2.0 on GitHub, and access continues for Gemini Code Assist Standard and Enterprise licenses, Google Cloud, and paid API keys. The successor is Antigravity CLI, a closed-source Go binary that keeps Agent Skills, Hooks, Subagents, and Extensions (now Antigravity plugins) and adds asynchronous background work, sharing its architecture with the Antigravity desktop app. Continuum is not a Google fork and does not replace either of them. It is the free multi-provider workbench that runs Google-side agents next to Claude Code and Codex, with worktrees, phone control, gauges where a provider exposes them, and a local spend ledger. The argument here is not that Google's agents are weak. It is that they are one engine in a day that usually has three.

Choose Continuum when

You want Gemini or Antigravity beside Claude and Codex in one sidebar, with worktree panes, iPhone approve, and multi-provider analytics instead of a Google-only surface.

Choose Gemini CLI / Antigravity when

You live inside Google tooling, hold a Code Assist license or an Antigravity plan, and want the native CLI with no extra workbench around it.

Google agent alone vs Continuum host

In Continuum

Google agent in a multi-provider day

09:45

Continuum Code: a Google-side session on feature A, a Claude worktree on feature B. One sidebar, two isolated checkouts, no shared index to corrupt.

11:20

Same ticket, two engines. Gemini takes one worktree and Claude another, and you read both diffs before either becomes a PR.

12:30

Plan ready on the Google-side session while you are at lunch. Approve it from the iPhone; the host keeps running.

16:00

Usage tab shows combined spend by repo and provider, so the Google rail is not a separate invoice you reconcile later. Keep the cleaner diff, ship it.

In Gemini CLI / Antigravity

Native Google CLI day

09:45

Run Antigravity CLI, or Gemini CLI if a Code Assist license or paid API key still entitles you. Full Google-side quality in Google's own surface.

11:20

Skills, hooks, and subagents behave exactly as documented, with nothing between you and the vendor's tooling. On a Google-only stack that is the shortest path there is.

12:30

Stay at the keyboard. There is no phone client on this path and no second engine to compare against.

16:00

Usage lives in Google account views, priced on Google's rail. Cross-provider spend by repo is a different app's job.

02

Monday path

Monday with Google-side agents in Continuum

Install, connect, first session - steps you can run the same day.

01

Work out which rail you are on first. Free, AI Pro, and Ultra lost Gemini CLI on 18 June 2026; a Code Assist Standard or Enterprise license, Google Cloud, or a paid API key still works. Everyone else moves to Antigravity CLI - see the Antigravity CLI guide.

02

Install Continuum on the Mac, then confirm the Google-side provider authenticates in Settings before you need it in front of anyone. A failed probe on Monday is cheaper than a failed demo on Thursday.

03

Spawn a Google-side session in the Code tab for a Google-rail ticket, in its own git worktree so it cannot collide with anything else.

04

Spawn a Claude or Codex peer on the same repo when you want a second opinion on the same ticket. Both land in one sidebar with their own checkouts.

05

Pair the iPhone with the QR code once. Approve and interrupt then work across engines, not just Claude.

06

Check the Usage tab after history lands: Google-side rows join the same ledger as Claude and Codex, priced from the bundled rate table.

07

Keep the native CLI installed for Google-only work and for anything already wired into Google Cloud. Continuum is not trying to be your only terminal.

08

If a brand-new Gemini model id is missing from the picker, check the catalog in your build - the bundled catalog and live probes refresh per release.

How Continuum runs Google-side agents

How Continuum runs Gemini / Antigravity

  • Google-side agents are providers in Continuum's catalog: the app spawns the official tooling under your own auth rather than proxying Google through a Continuum endpoint.
  • Peers stay first-class in the same sidebar - Claude Code over a PTY, Codex through the ACP harness - so one repo can hold a Gemini session and a Claude session at once.
  • Code panes attach regardless of engine: chat, plan, diff with per-hunk staging, PR, terminal, artifacts.
  • Worktree mode gives each session an isolated checkout, which is what makes running two engines on one ticket safe. See git worktrees.
  • The iPhone and Watch clients pair to the daemon on whichever host runs the agent, so approve and interrupt reach a Google-side session the same way they reach Claude.
  • Analytics ingest Google-side usage where a parser exists and price it from the bundled LiteLLM snapshot, so Gemini rows sit beside Claude and Codex in the same $ by repo view.
  • Provider enablement flags hide engines you do not use, so a Google-only or Claude-only Code tab stays calm instead of listing six agents you never pick.

Gemini / Antigravity host matrix

Continuum cells describe the cockpit around Google's engine, not a re-score of model quality. Where the native CLI is simply better at being a CLI, the row says so. Money detail lives in Gemini Code Assist pricing.

Multi-provider layering

01 · Layering

Engine versus cockpit.

Gemini CLI and Antigravity CLI are engines. Continuum is the multi-provider workbench that hosts them next to Claude and Codex, adds worktrees and review panes, and puts the whole thing on a phone. Provider enablement flags hide the engines you do not use, so hosting more agents does not mean a noisier Code tab.

02 · The 2026 transition

Which Google rail you are actually on.

Since 18 June 2026 the free, AI Pro, and Ultra rails no longer reach Gemini CLI; Code Assist Standard and Enterprise, Google Cloud, and paid API keys still do, and the Apache-2.0 repo is untouched. Everyone else uses Antigravity CLI, which is closed source and Go. Continuum spawns whichever one you are entitled to rather than pretending the split does not exist. Background in the Gemini CLI guide.

03 · Peers

Google is not the only good agent.

Continuum's product bet is that most engineers run two or three engines in a week, so the useful unit is the workbench, not the vendor. Google-native surfaces optimize the Google-only case and are excellent at it. Compare the terminals directly in Gemini CLI vs Codex.

04 · Mobile and ledger

Continuum ops surfaces.

Phone approve, per-account quota gauges, and a local dollar ledger by repo and provider are Continuum surfaces. Do not expect them from a Google CLI, and do not expect Continuum to reproduce Google Cloud's own billing console.

05 · When native wins

Stay Google-only if that is the whole stack.

If you never leave Google tooling, hold a Code Assist license, and want zero product surface between you and the vendor, Continuum is optional chrome. It earns its place when peers, hosts, accounts, and cost visibility start to matter.

05

Coexistence

Stack recipe

Same engine. Bigger cockpit.

Stack recipe: keep the native CLI for pure Google days and for anything wired into Google Cloud. Add Continuum when the day is multi-provider - a Gemini session and a Claude session on the same repo in separate worktrees, approve from the phone, then one ledger that shows what both cost. Continuum hosts the engine; it never rebrands Google's models as its own.

What you pay

Continuum

App + your labs

$0 for the app on Mac, web, iPhone, and Watch. Bring your own keys or the Claude and ChatGPT plans you already pay for, and Continuum takes no cut. Optional hosted inference: Plus $25/mo, Max 100 $100/mo, Max 200 $200/mo, Ultra $500/mo. Google-side sessions bill Google under your own plan, license, or API key.

Gemini CLI / Antigravity

Their bill

Gemini CLI stopped serving free, Google AI Pro, and Ultra users on 18 June 2026; Gemini Code Assist Standard and Enterprise licenses, Google Cloud, and paid API keys keep working. Everyone else moves to Antigravity CLI, which has a free Individual tier with basic weekly rate limits, higher ceilings and a credit pool on Google AI Pro ($19.99/mo) or AI Ultra (from $99.99/mo), and consumption pricing for organizations through Google Cloud. Code Assist Standard lists around $19/user/mo on annual terms. Checked August 2026.

How to compare

Total cost of work

Continuum hosts Google's engine; it does not resell it. The only Continuum-billed inference is the optional hosted SKUs, and they are never used for a session you run under your own Google auth.

Gemini CLI / Antigravity plans checked 3 August 2026 against their pricing page. Vendors reprice often - if you spot a stale figure, tell us and we will fix it. Continuum never marks up a session it runs under your own login.

Questions

Gemini CLI / Antigravity + Continuum.

Deep dives: docs, providers, sessions.

No. Google stopped serving Gemini CLI for free, Google AI Pro, and Ultra users on 18 June 2026. If your organization has a Gemini Code Assist Standard or Enterprise license, uses Google Cloud, or holds a paid API key, access continues. Everyone else moves to Antigravity CLI.

Antigravity CLI, a Go binary that keeps Agent Skills, Hooks, Subagents, and Extensions (renamed Antigravity plugins) and adds asynchronous background workflows. It is closed source, unlike the Gemini CLI repo, which stays Apache-2.0 on GitHub. Setup notes are in the Antigravity CLI guide.

Yes. Google-side agents are providers in Continuum's catalog and spawn under your own auth, with the same Code panes, worktrees, and mobile control the Claude and Codex sessions get.

Yes, and it is one of the better reasons to use a workbench. Spawn both in separate git worktrees on the same repo, read the two diffs side by side, and keep the cleaner one. Neither agent can stomp the other's checkout.

No. Sessions Continuum spawns under your own Google auth are billed by Google at Google's rate, with no Continuum cut. The optional Continuum hosted plans are a separate SKU you have to opt into.

Yes, once the session runs through Continuum's daemon on a paired host. Approve, interrupt, and reply behave the same across engines rather than being Claude-only.

Continuum parses local session history and prices it from a bundled rate table, so Gemini rows join Claude and Codex in one $ by repo, provider, and day view. Consumption billed through Google Cloud still shows in Google's console; the Continuum ledger is for comparing engines, not replacing an invoice.

Only if nothing you own still calls it. A Code Assist license or paid API key keeps it working, and the repo is unchanged. If you are cleaning up, follow uninstalling Gemini CLI.

Not always. The bundled catalog and pricing table sometimes trail a launch by a release, and an unpriced model id shows tokens without a dollar figure rather than a wrong one. Live probes and the bundled catalog refresh with each Continuum build.
