Editors and completions
Google's coding tools for consumer accounts now run through Google Antigravity: its own IDE and CLI, plus extensions for VS Code, Visual Studio, JetBrains, Zed and Xcode, signed in with a personal Google Account. Antigravity is free with no subscription. Consumer access to Gemini Code Assist in the IDE and Gemini CLI ended on June 18, 2026.
GitHub documents Copilot extensions for VS Code, Visual Studio, JetBrains IDEs, Xcode, Eclipse, Neovim, Zed and more, with agent mode in five of them. Every plan includes Copilot CLI and the GitHub Copilot desktop app. GitHub says features vary by editor.
For completions, Antigravity's $0 Individual plan lists unlimited Tab completions in the Antigravity IDE, and paid plans raise agent limits, not completions. Google does not say whether Tab completions also work in its VS Code or JetBrains extensions, so that is not verified. Copilot Pro documents unlimited inline suggestions and next edit suggestions that use no AI credits. Copilot Free caps completions at 2,000 a month.
Cloud agents that open pull requests
Jules, Google's cloud agent (a beta for users 18 and over), runs tasks in a cloud virtual machine on GitHub repositories you connect, and can publish a branch or open a pull request. Its limits page lists 15 tasks a day and 3 at once on the free tier, with Gemini 2.5 Pro, and 100 a day and 15 at once on Google AI Pro, with higher access to the latest model.
Copilot's cloud agent, from Pro up, researches a repository, plans, codes in a cloud environment and opens a pull request. Its documented limits: GitHub-hosted repositories only, one repository, branch and pull request per task, a 59-minute session limit, and AI credits for each task. Pro+ and Max can also hand tasks to Claude and Codex agents.
Pull request review
Copilot Pro includes Copilot code review on GitHub pull requests, run manually or automatically on pull requests you create, plus file-diff review in editors. GitHub puts a review at about $0.05 to $1 of AI credits on its Lite setting and $0.25 to $5 on Balanced. Copilot Free offers only "Review selection" in VS Code.
Google documents no pull request reviewer on any consumer plan (Ultra included). The consumer Gemini Code Assist on GitHub app, which covered Google AI Pro and Ultra users, was deprecated on June 18, 2026 and shut down on July 17, 2026, and Google documents no replacement. Jules answers comments only on its own pull requests.
Which models, from which companies
The Gemini app lists only Google models; on Google AI Pro that means 3.8 Flash and 3.1 Pro. Other companies' models appear only inside Antigravity, whose Pro column lists Claude Sonnet 5.5 and Opus 5.5 (not on trial subscriptions), Claude 4.6 models and GPT-OSS-120b, and Google marks the 4.6 models and GPT-OSS-120b for removal on November 2, 2026. Free and Plus do not get the Claude 5.5 models.
Copilot Pro offers models from Anthropic, OpenAI, Google, xAI, Moonshot and Microsoft, among them Claude Sonnet 5.5, GPT-6 Luna, Grok 4.7 and Gemini 3.8 Flash. So a Gemini model is available inside Copilot, paid from its credits: GitHub lists Gemini 3.8 Flash on Pro, Pro+ and Max. Claude Opus 5.5, Claude Fable 5.1, GPT-6.1 Sol and GPT-5.6 Sol need Pro+ at $39 a month. Copilot Free uses automatic model selection only, and GitHub does not list which models it uses.
Limits and what extra use costs
Copilot Pro includes 1,500 GitHub AI Credits a month, 1,000 base plus 500 flex credits that GitHub says may change, at $0.01 a credit. Chat, agent mode, code review, the cloud agent and the CLI draw on them; completions do not. Past the allowance, use is billed against a dollar budget you set. Pro+ has 7,000 and Max 20,000.
On Google's side, Jules counts tasks per rolling 24 hours. Antigravity's free tier has basic weekly rate limits; on Pro, the quota refreshes every five hours up to a weekly limit, with AI-credit overages. We did not find a price for those credits on the pages we checked.
What else you are paying for
Google AI Pro is a general assistant plan with coding tools inside. It documents the Gemini app with a 1 million token context and uploads of up to 1,500 pages, Gemini in Gmail, Docs, Sheets and Vids, Deep Research, image and video generation, and 5 TB of storage. It is $19.99 a month or $199.99 a year paid up front, and students can get it free for a year after verification.
GitHub scopes Copilot to software work: code, repositories and development concepts. Image and video generation are not documented for Copilot. Around the code, it documents Copilot Spaces, custom agents, MCP servers and, on paid plans, Copilot Memory (public preview). Copilot Pro is $10 a month, monthly only for new subscribers. Neither vendor states whether US sales tax is included, so all prices here are before tax.
Privacy and training
Training is on by default on both. Google uses Gemini chats for training for users 18 and over; turning off Keep Activity stops it, but chats are still kept for up to 72 hours and memory of past chats stops working. The pages we checked do not say whether that setting also covers Jules or Antigravity. Since April 24, 2026, GitHub may train on interaction data from Copilot Free, Pro, Pro+ and Max by default; set "Allow GitHub to use my data for AI model training" to Disabled.
What we have not tested
Nothing here shows whose agent writes working code or whose reviews catch real problems. Run the same task in both with our code repair, code spec and code refactor kits, and on Copilot note how many credits each task uses. See our methodology. Related: Gemini vs Cursor and Cursor vs GitHub Copilot.
