Gemini CLI Review 2026: No Longer Free, Who Can Still Use It

Most reviews of Gemini CLI still lead with a generous free tier. That tier is gone. Google announced on May 19, 2026 that it was unifying its terminal work into Antigravity, and the notice at the top of the Gemini CLI site now tells unpaid-tier and Google One users that the CLI has been replaced. Some docs pages on the same site still show the old free quota table, so go by the dated notice, not the table.

What remains is a capable, open source agent for a narrower buyer: an organization that pays for Gemini Code Assist, or a developer who wants to run Google's models through a paid API key in the terminal. This review covers what Gemini CLI does, who can still sign in, what each route costs at Google's list prices, and when Antigravity CLI, Claude Code, Codex or OpenCode is the better buy. Changes like this one are what the Devshot daily brief tracks.

Gemini CLI is an open source AI agent for the terminal, released by Google under the Apache 2.0 license. It queries and edits large codebases, debugs from natural-language prompts, automates tasks such as complex rebases and can run non-interactively inside scripts. Context lives in GEMINI.md files, and MCP servers add tools such as media generation.

The software stays free to install with npm, Homebrew or npx. The change in 2026 is about who Google will serve requests for. Since the switch, the model calls behind the CLI need a paid Code Assist license, a paid Gemini API key or Vertex AI.

You install the CLI, then choose one of three ways to authenticate. Signing in with Google works when your organization holds a Gemini Code Assist Standard or Enterprise license, and you set a Google Cloud project first. A Gemini API key from AI Studio lets you pick the model and pay per token. Vertex AI covers enterprise setups with Google Cloud terms and billing.

The quota model differs by route. Code Assist seats count model requests per user per day, and Google notes that one prompt in agent mode can trigger several model requests, so a daily request cap covers fewer prompts than it sounds. An API key has no daily cap of that kind; you pay for every token instead, which suits long sessions and scripted runs. The /stats model command shows your usage and limits during a session.

Methodology: on 21 October 2026 we read Gemini Code Assist pricing, the Code Assist quotas page, the Gemini API pricing page and Google's transition announcement. Every figure below comes from those pages; there is no hands-on timing in this review. How we weigh a page is on how we rate.

Seat route. Gemini Code Assist Standard costs $22.80 per user per month on monthly terms, and Enterprise costs $54 monthly or $45 on an annual commitment. Enterprise raises the daily request quota to 2,000 per user, counted across every Gemini model, like Standard's. A ten-person team on annual Standard pays $190 a month, our arithmetic on the per-seat price. Toolradar profiles Gemini Code Assist separately from the CLI.

API key route. You pay Gemini API list rates for the model you choose. As a worked example, take 30 million input and 1 million output tokens in a month, a plausible load for an agent that rereads files. On Gemini 3.8 Flash that is $26.25 through December 31, 2026 and $52.50 from January 1, 2027, when both Flash rates double. On Gemini 3.1 Pro Preview, with prompts under 200,000 tokens, the same month is $72.00. Search grounding on Gemini 3 and newer models includes 5,000 free requests a month, then $14 per 1,000.

The comparison that matters: at that load, a monthly Standard seat costs less than Flash on an API key, and far less than Pro Preview, as long as the daily request cap holds. API keys win for bursty use, scripts and anyone who needs a specific model. For the wider coding-tool bill, see AI coding assistant pricing in 2026.

Gemini CLI fits a team that already pays for Gemini Code Assist. The seat covers the IDE extension and the CLI from one daily quota, the CLI keeps getting updates, and Google says Standard and Enterprise access is unchanged. It also fits developers on a Google Cloud stack who want a scriptable, open source agent billed through an API key or Vertex AI.

Skip it if you came for the free tier. Google's own replacement for individuals is Antigravity CLI, which keeps Agent Skills, Hooks, Subagents and Extensions (renamed plugins) and runs on a no-cost Individual plan. Skip it too if you want Google's newest model: the README says Gemini CLI has not been optimized for Gemini 4 Argon and points to Antigravity for it. Developers who want one flat personal subscription are better served by Claude Code or Codex, compared in Claude Code vs Codex.
