If you write code in 2026, you have probably watched an AI agent edit your files from a terminal prompt. The two names that come up most are Claude Code and Gemini — Anthropic's terminal-native agent and Google's coding assistant. We already compared the two as chatbots in our
Gemini vs Claude head-to-head, but coding is a different job. They charge differently, run different models — and one quietly ended its free ride in June 2026.
The Price of Entry
Claude Code needs a paid Claude plan — there is no free tier. Pro costs $20 a month ($17 if you pay annually) and includes Claude Code; Max is $100 or $200 a month for higher limits.
Gemini's story changed this year. Gemini CLI launched in June 2025 with a generous free tier — 60 requests a minute, 1,000 a day. On June 18, 2026, Google cut off free, AI Pro and AI Ultra accounts and pointed individuals to its new Antigravity CLI, with a smaller free weekly quota. Teams can still buy Gemini Code Assist Standard at $19 per user a month annually ($22.80 month-to-month), or Enterprise at $45 ($54 monthly).
Claude's entry is simpler — one $20 subscription. Gemini's paid route starts at a similar $19, and its cheapest route for individuals is now Antigravity's free tier.
The Models Doing the Work
Claude Code runs on Claude Sonnet 5.5 by default, Opus 5.5 for the hardest tasks, with a 1-million-token context window. On SWE-bench Verified (500 real GitHub issues), Sonnet 5 scores 85.2% on third-party trackers, and the previous flagship Opus 4.5 scored 80.9%.
Gemini runs on Gemini 3 Pro, also with a 1-million-token context. Google reports 76.2% on SWE-bench Verified for Gemini 3 Pro. The gap is real but small, and test setups move the numbers a few points either way.
Where Each One Works Best
Claude Code was built terminal-first: it lives in your shell, plans multi-file changes, runs tests and fixes what breaks. It also has a VS Code extension. It is the pick when an agent must roam a whole codebase unsupervised — the same reason it appears in our ChatGPT vs Claude for coding comparison. Gemini Code Assist lives inside VS Code, JetBrains IDEs and Android Studio, and plugs straight into Google Cloud. Antigravity, Google's newer IDE, is a multi-agent workspace where several agents work in parallel. Shopping beyond these two? Our roundup of AI coding assistants compares Replit and Cursor. The Verdict
Pick Claude Code for the strongest coding agent on one flat subscription — especially long, multi-file jobs where the agent plans, builds and tests. Pick Gemini if your team already runs on Google Cloud, or if Antigravity's free tier is enough for your side projects.
Whatever you pick, ignore any early-2026 guide still promising a free Gemini CLI — that door closed in June. Try both on a real project for a week; the one that fits your workflow is the right one.
