Pricing Comparison

Pricing is one of the biggest differentiators between Gemini Code Assist vs Copilot, and the structures are quite different.

GitHub Copilot Pricing

Plan	Price	Premium Requests	Best For
Free	$0/month	50/month	Trying it out
Pro	$10/month	300/month	Individual developers
Pro+	$39/month	1,500/month	Power users needing all models
Business	$19/user/month	Varies	Teams and organizations
Enterprise	$39/user/month	Varies	Large enterprises with private codebase indexing

Copilot Pro is free for verified students, teachers, and maintainers of popular open-source projects. All paid plans include unlimited inline code completions and chat interactions using included models (GPT-5 mini, GPT-4.1, GPT-4o). Premium requests are consumed when using advanced models like Claude Opus 4 or OpenAI o3. Once you exceed your monthly allowance, additional premium requests cost $0.04 each.

Gemini Code Assist Pricing

Plan	Price	Best For
Free (Individual)	$0/month	Personal projects, up to 180K completions/month
Standard	$19/user/month	Teams needing higher quotas and integrations
Enterprise	$45/user/month	Large organizations with private codebase indexing

The free tier includes 180,000 code completions per month plus access to agent mode, chat, unit test generation, and debugging support — all powered by a 128K-token context window. Users on Google AI Pro or Ultra subscriptions get higher daily model request limits shared across Gemini Code Assist, Gemini CLI, and agent mode.

Pricing Verdict

For individual developers on a budget, GitHub Copilot Pro at $10/month is cheaper than any paid Gemini plan. But Gemini’s free tier is dramatically more generous — 180,000 completions versus just 2,000 for Copilot Free. If you only need code completions without premium model access, Gemini’s free plan may be all you need.

For teams, both charge $19/user/month at the standard tier. Copilot Business and Gemini Standard are priced identically, so the decision comes down to features and ecosystem fit rather than cost.

Code Completion and Quality

Both tools provide inline code suggestions as you type, autocompleting lines, functions, and even multi-line blocks based on context from your current file and project.

GitHub Copilot

Copilot uses a multi-model architecture. Included models handle standard completions (GPT-5 mini, GPT-4.1, GPT-4o), while premium requests unlock more powerful models for complex tasks. Copilot works with a 128,000-token context window and delivers quick, concise suggestions optimized for speed.

Copilot has been shown to accept code at strong rates across production environments, with GitHub reporting a 72% satisfaction rate among its developer base. Its suggestions tend to be terse and practical — you get working code fast with minimal explanation.

Gemini Code Assist

Gemini Code Assist runs on the Gemini model family, with agent mode using Gemini 2.5 Pro for complex tasks. The standout technical advantage is the 1-million-token context window, which means it can process significantly more of your codebase when generating suggestions.

On the SWE-bench benchmark (a standard test for evaluating AI coding ability on real GitHub issues), Gemini scored 63.8% compared to Copilot’s 33.2% baseline with GPT-4o. That said, benchmarks do not always translate directly to day-to-day coding experience, where factors like latency and suggestion relevance matter just as much.

Gemini’s suggestions tend to include more detailed reasoning and educational context, which can be helpful for learning but slower if you just want the code.

Quality Verdict

Gemini wins on raw benchmarks and context window size. Copilot wins on speed and the ability to choose from multiple frontier models (including Claude Opus 4 and o3) via premium requests. For most day-to-day coding, both produce high-quality completions.

Agent Mode

Agent mode is where both tools have invested heavily in 2025, moving beyond simple completions into autonomous multi-step task execution.

GitHub Copilot Agent Mode

Copilot’s coding agent is generally available for all paid subscribers. When you assign a GitHub issue to Copilot or trigger it from VS Code, the agent:

• Spins up a secure development environment powered by GitHub Actions
• Analyzes the issue and creates a plan
• Makes multi-file edits, runs terminal commands, and iterates on errors
• Opens a draft pull request with its changes
• Pushes commits as it works, with full session logs for transparency

You can also delegate tasks from the VS Code agents panel, from any page on GitHub, or through a “Delegate to coding agent” button. The agent supports MCP (Model Context Protocol) for integrating with external tools and services.

A unique Copilot feature is agentic memory — the agent can learn and store useful information about a repository over time, improving the quality of its output on future tasks.

Copilot’s agent mode is available in VS Code, JetBrains, Eclipse, and Xcode (the latter three in public preview).

Gemini Code Assist Agent Mode

Gemini’s agent mode takes a different architectural approach. Instead of a single agent working through a plan alone, it uses a multi-agent collaboration system where specialized agents (developer, tester, security analyst) work together and check each other’s output.

Key capabilities include:

• Multi-file edits with full project context
• Plan generation that you can review and approve before execution
• Built-in tool usage (grep, file read/write, MCP servers, REST API calls)
• Human-in-the-loop oversight at each step
• 1M-token context window for understanding large codebases

Agent mode is available in VS Code and IntelliJ IDEs. It is still labeled as preview, but it ships on the free tier — unlike Copilot where the coding agent requires a paid plan.

Agent Mode Verdict

Copilot’s agent mode is more mature and deeply integrated with GitHub workflows (issues, PRs, Actions). Gemini’s multi-agent approach is architecturally interesting and the free availability is a significant plus. If your team lives in GitHub, Copilot’s agent is the natural choice. If you want agent capabilities without paying, Gemini wins.

• Agentic memory across repository interactions
• Audit logs and compliance controls

Gemini Code Assist Enterprise ($45/user/month)

• Private codebase indexing and customization
• 1M-token context window
• Analytics dashboard (daily active use, acceptance rates, lines of code accepted)
• Enterprise-grade security and data boundaries
• Google Cloud ecosystem integration
• MCP support for custom tool integration
• Multi-agent collaboration with security agent oversight

Enterprise Verdict

Both offer private codebase indexing and strong security controls. Copilot Enterprise is $6/user cheaper and benefits from native GitHub integration, which most development teams already use. Gemini Enterprise is the better fit for organizations deeply invested in Google Cloud Platform.

Code Review

Both tools offer AI-powered code review, but with different strengths.

GitHub Copilot can review pull requests directly on GitHub.com, suggesting fixes and identifying issues inline. In head-to-head testing, Copilot’s code reviewer has been noted for more consistently catching problems and providing actionable suggested code corrections.

Gemini Code Assist performs code reviews within supported IDEs. Its multi-agent approach means a security-focused agent can flag vulnerabilities, but real-world reports suggest it occasionally misses issues that Copilot catches on pull requests.

Neither tool should replace human code review entirely. Both generate code with approximately 40-44% vulnerability rates according to security studies, which underscores the importance of human oversight.

Final Verdict

The Gemini Code Assist vs Copilot decision largely comes down to ecosystem alignment.

GitHub Copilot remains the default recommendation for most developers. Its $10/month Pro plan is the cheapest paid option, it supports more IDEs, offers multi-model flexibility, and its native GitHub integration is unmatched. The 20-million-user community means more shared workflows, custom GPTs, and third-party integrations.

Gemini Code Assist is a serious contender that beats Copilot in specific areas: a dramatically better free tier (90x more completions), the largest context window in the market (1M tokens), and strong benchmark performance. For Google Cloud teams or budget-conscious developers who can work within the free tier, it is the smarter pick.

If you are starting fresh with no ecosystem commitment, try both free tiers and see which one fits your coding style. Gemini gives you far more room to test on the free plan, while Copilot’s paid plans offer more flexibility with model selection. Either way, you are getting a capable AI coding assistant that will meaningfully speed up your development workflow.
