Should you use Claude or Gemini for coding?
Use the one whose coding tools and plans fit how you work, because both companies now pitch their top models for complex software engineering and long-running agents. Claude is Anthropic's model family, used most directly through Claude Code. Gemini is Google's, used most directly through Antigravity. The real differences are the agents, the prices and what each plan includes.
This page sticks to facts from Anthropic's and Google's official docs as of 24 October 2026. It does not cite benchmarks or declare a winner. Model quality on your codebase is something to test yourself.
Which Claude and Gemini models are built for coding?
Claude. Anthropic's models overview lists four current models, all with a 1M token context window and 128K output tokens:
- Claude Fable 5.1: "For demanding reasoning and long-horizon agentic work."
- Claude Opus 5.5: "For long-running agentic coding and knowledge work." Anthropic says to "start with Claude Opus 5.5 for most workloads."
- Claude Sonnet 5.5: "The best combination of speed and intelligence."
- Claude Haiku 5.5: "For high-volume, latency-sensitive tasks such as classification, extraction, and routing."
Gemini. Google's Gemini API models page lists:
- Gemini 4 Argon: "Our flagship reasoning model with a unified 1M context window and long decodes up to 1M tokens." The pricing page adds that it is "built for complex software engineering."
- Gemini 3.8 Flash: "Our most intelligent Flash model, engineered for long-horizon software engineering, autonomous agents, and complex enterprise workflows."
- Older and lighter models such as Gemini 3.6 Flash and Gemini 3.5 Flash-Lite.
So both lineups have a flagship for hard, long tasks and a faster model for everyday work. In practice you will often pick a model through your coding tool rather than the API.

What coding agents does each one offer?
Claude Code. Claude Code is "an agentic coding tool that reads your codebase, edits files, runs commands, and integrates with your development tools." It runs in the terminal, VS Code, JetBrains IDEs, a desktop app and the browser, from one engine. Model aliases make switching easy: opus, sonnet and haiku map to the 5.5 models on the Anthropic API, and fable maps to Fable 5.1.
curl -fsSL https://claude.ai/install.sh | bash
cd your-project
claude --model opus
Antigravity. Google's Antigravity spans a desktop app for managing agents, the agy CLI, extensions for VS Code, JetBrains, Visual Studio, Zed and Xcode, a standalone IDE and a Python SDK. It reviews work through artifacts such as implementation plans, diffs and browser recordings. Its models page notes that Gemini 4 Argon is available in the app, the CLI and the IDE extensions, but "Not available in Antigravity IDE."
curl -fsSL https://antigravity.google/cli/install.sh | bash

Gemini CLI. The open source Gemini CLI still works, but its README says it "was replaced by Antigravity CLI on June 18th, 2026" for unpaid tier and Google One users, and that it "has not been optimized for Gemini 4 Argon." The Gemini CLI vs Claude Code guide covers who can still use it.
Jules. Google's plans page describes Jules as "an asynchronous coding agent that is currently in beta," with higher limits on Pro and Ultra.
For a head-to-head on the two main agents, see Claude Code vs Antigravity.
How much do Claude and Gemini cost for coding?
Subscriptions, as of October 2026:
- Claude (pricing): Free ($0, no Claude Code), Pro ($20 a month billed monthly or $17 a month billed annually), Max (from $100 a month for 5x or 20x Pro usage). Team Standard seats are $25 a month billed monthly. The page says "Claude Code is included in all paid plans."
- Google AI (plans, US prices): Free ($0), Google AI Plus ($4.99 a month), Google AI Pro ($19.99 a month, includes Gemini 4 Argon), Google AI Ultra ($99.99 a month for 5x Pro limits, or $199.99 for 20x). Antigravity's pricing page offers a $0 individual plan with "Basic weekly rate limits," and higher limits on Pro and Ultra.
API prices per million tokens, standard paid tier, as of October 2026:
| Model | Input | Output |
|---|---|---|
| Claude Fable 5.1 | $10 | $50 |
| Claude Opus 5.5 | $4 | $20 |
| Claude Sonnet 5.5 | $2 | $10 |
| Claude Haiku 5.5 | from $0.10 | from $0.50 |
| Gemini 4 Argon | $2 (rises to $4 on 1 Dec 2026) | $10 (rises to $20 on 1 Dec 2026) |
| Gemini 3.8 Flash | $0.75 (rises to $1.50 on 1 Jan 2027) | $3.75 (rises to $7.50 on 1 Jan 2027) |
Claude prices come from Anthropic's models overview, and Gemini prices from the Gemini API pricing page, which also says Gemini 4 Argon "is not available on the Free tier" while Gemini 3.8 Flash is free of charge on the free tier. Output prices include thinking tokens on Gemini. Agents use many tokens per task, so a subscription is often simpler than paying per token.
Can you use Claude and Gemini together?
Yes, and many developers do. A few routes:
- Antigravity with Claude models. Antigravity's models page lists Claude Sonnet 5.5 and Opus 5.5 for paid Google AI Pro (non-trial), Ultra and Enterprise users. Its plans page also lists third-party model access as an Ultra benefit, so check your plan in the app.
- Multi-model editors and agents. Tools such as Cursor and Cline let you choose Claude or Gemini models per task. See Cline vs Cursor.
- Claude on Google Cloud. Anthropic's models overview lists IDs for Claude models on Google Cloud, so teams on Google Cloud can reach Claude there too.
To keep your setup portable, put shared project instructions in an AGENTS.md file, which both Claude Code and Antigravity can read, and write reusable workflows as Agent Skills. Claude Code reads skills from .claude/skills/ and Antigravity from .agents/skills/, so keep one copy and link or copy it.
Which should you pick?
Start from your budget and the tools you want, not from a leaderboard.
Claude tends to fit when:
- You want Claude Code as your main agent, across terminal, IDE, desktop and web.
- You want Anthropic's flagship models, including Fable 5.1 for the hardest long-running tasks.
- You already pay for Claude Pro, Max or a Team plan.
Gemini tends to fit when:
- You want to start coding with an agent at $0 through Antigravity.
- You already pay for Google AI Pro or Ultra, or your company uses Gemini Enterprise.
- You want a low-cost fast model on the API, such as Gemini 3.8 Flash, with a free tier to start.
Whichever you choose, run the same two or three real tasks from your own repo in both before you commit. That will tell you more than any comparison page. The Claude Code models guide explains how to switch between Claude models once you are set up.
Keep your prompts and skills portable
Models change every few months, but good instructions keep their value. Kipt keeps your prompts and Agent Skills as Markdown in a private GitHub repo you own, and installs every skill into Claude Code or Codex with one npx skills add command. If you have a coding prompt you reuse with Claude or Gemini, the free SKILL.md generator turns it into a skill folder in your browser.
