Gemini CLI is Google's open-source AI agent for the terminal. Its standout traits are a 1M-token context window that can hold entire codebases and a free tier generous enough for real daily work with just a personal Google account. It supports MCP servers, Google Search grounding, and shell command execution in an agentic loop.

Runs on: macOS · Linux · Windows (terminal)|Best for: Developers who want frontier-agent capability with huge context at zero cost
Whichever AI agent you choose, Standard Compute gives you unlimited LLM compute at one flat monthly price. No rate limits, no per-token billing.
Yes — with a personal Google account you get a free quota generous enough for real daily use (the most generous of any frontier-model agent). Paid usage via the Gemini API or Code Assist plans removes the limits and adds enterprise data controls.
Huge-context work and zero-cost experimentation: exploring or summarizing large codebases with its 1M-token window, and giving developers a free terminal agent that's genuinely capable. It's the obvious first agent to try before paying for anything.
For exploration, smaller edits, and large-context analysis, often yes. For complex multi-file changes, Claude Code's output quality still leads. A common setup: Gemini CLI for free heavy-context work, Claude Code (or another paid agent) when correctness matters most.
