We wrote this from our own profiles of both tools, verified on September 29, and from our first benchmark task, where only the Claude Code run is finished; we used no third-party benchmarks and took no vendor payments.

Is Gemini CLI better than Claude Code? The short answer

Pick Gemini CLI if you want an open-source (Apache 2.0) terminal agent that you can authenticate with a Google account, an AI Studio API key or Vertex AI, and you can live with the fact that its plans page shows no USD prices. Pick Claude Code if you already have or will buy a Claude Pro, Max, Team or Enterprise plan, or an Anthropic Console account, and want one agent across terminal, IDE, desktop and web. Only Claude Code has a completed run on our benchmark task so far (5 of 5 tests); Gemini CLI is still pending, so we make no performance claim about it.

Based on our profiles of both tools verified on September 29 and the first benchmark task (Claude Code run on October 2; Gemini CLI and OpenAI Codex pending).
