How to Use Claude Code with Gemini in YOLO Mode (2026)

How to Use Claude Code with Gemini in YOLO Mode (2026)

Claude Code is Anthropic's CLI for agentic coding, but it is not limited to Claude models. With the right configuration, you can run Google's Gemini models through Claude Code -- and combine that with YOLO mode (auto-accept) for a fully autonomous coding workflow that requires zero manual approvals.

This guide shows you how to set up Gemini as the model provider in Claude Code, enable YOLO mode, and configure safety guardrails so you do not accidentally delete your entire project.

What Is YOLO Mode?

YOLO mode (the name comes from the community, though Anthropic officially calls it "auto-accept" or "dangerously skip permissions") tells Claude Code to automatically approve all tool uses -- file edits, terminal commands, and other actions -- without asking for your confirmation.

Normally, Claude Code asks you to approve every file write and shell command. This is safe but slow. YOLO mode removes that friction:

# Normal mode: Claude asks permission for every action
claude
# > "I'd like to edit src/auth.ts. Allow? (y/n)"

# YOLO mode: Claude acts without asking
claude --dangerously-skip-permissions
# > *edits src/auth.ts immediately*
# > *runs npm test immediately*
# > *fixes failing tests immediately*

Warning: YOLO mode can execute arbitrary shell commands on your machine. Use it only in sandboxed environments, containers, or repositories where you can easily revert changes with Git.

Why Use Gemini with Claude Code?

There are several reasons to swap in Gemini models:

Reason	Details
Cost	Gemini 2.0 Flash is significantly cheaper than Claude Sonnet
Speed	Gemini Flash has very low latency for simple tasks
Free tier	Google AI Studio offers generous free API usage
Context window	Gemini models support up to 1M tokens of context
Experimentation	Try different models for different types of tasks

Gemini 2.0 Flash, in particular, is extremely fast and cheap -- making it ideal for YOLO mode where the model might make many iterative calls.

Prerequisites

Before starting, make sure you have:

• Claude Code installed: npm install -g @anthropic-ai/claude-code
• A Google AI Studio API key: Free at aistudio.google.com
• Node.js 18+ installed
• Git for version control (essential safety net with YOLO mode)

Step 1: Get a Gemini API Key

1. Visit Google AI Studio.
2. Sign in with your Google account.
3. Click Get API Key in the left sidebar.
4. Click Create API Key and select a Google Cloud project (or create a new one).
5. Copy the API key.

The free tier gives you generous rate limits for Gemini 2.0 Flash:

Model	Free Tier Limit	Paid Rate
Gemini 2.0 Flash	15 RPM, 1M TPM	$0.10 / 1M input tokens
Gemini 2.0 Pro	2 RPM, 100K TPM	$1.25 / 1M input tokens
Gemini 2.5 Pro	5 RPM, 250K TPM	$1.25 / 1M input tokens

Step 2: Configure Claude Code to Use Gemini

Claude Code supports third-party models through OpenAI-compatible API configurations. Set the following environment variables:

# Set Gemini as the model provider
export CLAUDE_CODE_USE_BEDROCK=0
export ANTHROPIC_API_KEY="placeholder"

# Configure the model
export CLAUDE_MODEL="gemini-2.0-flash"

# Set Google AI as the provider
export MODEL_PROVIDER="google"
export GOOGLE_API_KEY="your-google-ai-studio-api-key"

Alternatively, you can use the --model flag when launching Claude Code:

claude --model gemini-2.0-flash

Using the Settings File

For a more permanent configuration, add the settings to your Claude Code config:

# Open Claude Code settings
claude config set --global model gemini-2.0-flash
claude config set --global provider google

Or edit the configuration file directly:

// ~/.claude/settings.json
{
  "model": "gemini-2.0-flash",
  "provider": "google",
  "apiKey": "your-google-api-key"
}

Using OpenRouter as a Proxy

An alternative approach is to use OpenRouter, which provides a unified API for multiple model providers:

export ANTHROPIC_BASE_URL="https://openrouter.ai/api/v1"
export ANTHROPIC_API_KEY="sk-or-your-openrouter-key"
export CLAUDE_MODEL="google/gemini-2.0-flash"

This approach works well because OpenRouter handles the API translation between Anthropic's format and Google's format.

Step 3: Enable YOLO Mode

Now combine Gemini with auto-accept mode:

# Basic YOLO mode with Gemini
CLAUDE_MODEL="gemini-2.0-flash" \
GOOGLE_API_KEY="your-key" \
claude --dangerously-skip-permissions

Adding Safety Guardrails

YOLO mode does not mean reckless. Configure an allowlist of permitted commands to prevent destructive actions:

# YOLO mode with command restrictions
claude --dangerously-skip-permissions \
  --allowedTools "Edit,Write,Read,Glob,Grep"

This allows file operations but blocks arbitrary shell commands. For a more permissive setup that still blocks the most dangerous operations:

// .claude/settings.json
{
  "permissions": {
    "allow": [
      "Read",
      "Write",
      "Edit",
      "Glob",
      "Grep",
      "Bash(npm test)",
      "Bash(npm run lint)",
      "Bash(npx tsc --noEmit)"
    ],
    "deny": [
      "Bash(rm -rf *)",
      "Bash(git push)",
      "Bash(sudo *)"
    ]
  }
}

Recommended Safety Setup

Before using YOLO mode, always set up a safety net:

# 1. Make sure you're in a Git repository
git status

# 2. Commit or stash all current changes
git add -A && git commit -m "checkpoint before YOLO mode"

# 3. Create a branch for YOLO work
git checkout -b yolo-experiment

# 4. Now run YOLO mode safely
claude --dangerously-skip-permissions

# 5. After YOLO mode, review all changes
git diff

# 6. If something went wrong, reset
git checkout main
git branch -D yolo-experiment

Step 4: Practical Workflows

Quick Bug Fixes

YOLO mode with Gemini Flash is perfect for rapid bug fixing:

claude --dangerously-skip-permissions \
  "fix the TypeScript errors in src/components/ and run tsc to verify"

Gemini Flash processes this quickly: it reads the error output, identifies the issues, makes fixes, and runs the type checker -- all without prompting you.

Test Generation

Generate tests for an entire module autonomously:

claude --dangerously-skip-permissions \
  "write comprehensive unit tests for all functions in src/utils/. \
   Use vitest. Run the tests and fix any failures."

Code Refactoring

Refactor code patterns across your project:

claude --dangerously-skip-permissions \
  "refactor all useState + useEffect patterns in src/components/ \
   to use React Query instead. Update imports and types."

Documentation Generation

Generate documentation from code:

claude --dangerously-skip-permissions \
  "add JSDoc comments to all exported functions in src/lib/. \
   Include parameter descriptions, return types, and examples."

Model Comparison for YOLO Tasks

Different models have different strengths in YOLO mode:

Task Type	Best Model	Why
Quick fixes, linting	Gemini 2.0 Flash	Fast, cheap, good enough
Complex refactoring	Claude Sonnet	Better code reasoning
Test generation	Gemini 2.5 Pro	Great at understanding code
Multi-file architecture	Claude Sonnet	Stronger planning ability
Documentation	Gemini 2.0 Flash	Speed matters, quality is sufficient
Bug investigation	Gemini 2.5 Pro	Large context for reading many files

Troubleshooting

Common Issues

"Model not found" error: Make sure you are using the correct model identifier. Google AI Studio uses gemini-2.0-flash, while OpenRouter uses google/gemini-2.0-flash.

Rate limit errors: The free Gemini tier has strict rate limits (15 RPM for Flash). In YOLO mode, Claude Code can make many rapid requests. Either upgrade to a paid plan or add delays.

Context length issues: If Claude Code tries to read too many files and exceeds the context window, use a .claudeignore file to exclude irrelevant directories:

# .claudeignore
node_modules/
dist/
build/
.next/
coverage/
*.lock

Tool use compatibility: Not all models handle Claude Code's tool format perfectly. If you see parsing errors, try using OpenRouter as a proxy, which normalizes tool use across providers.

Frequently Asked Questions

Is YOLO mode safe? It is safe if you use Git, work on a branch, and restrict allowed tools. Never use YOLO mode on a production server or without version control.

Does Gemini work as well as Claude in Claude Code? For simple tasks (bug fixes, test generation, documentation), Gemini Flash performs well. For complex multi-file refactoring and architectural changes, Claude Sonnet is generally more reliable.

Can I use Gemini 2.5 Pro in YOLO mode? Yes, but the rate limits are lower and the cost is higher. Gemini 2.0 Flash is usually the better choice for YOLO mode because speed and cost matter more than peak quality.

Does this use my Anthropic credits? No. When configured with a Google API key, all requests go to Google's servers and use your Google AI Studio quota.

Wrapping Up

Using Claude Code with Gemini in YOLO mode gives you a fast, cheap, autonomous coding assistant. The combination of Gemini Flash's speed with auto-accept mode creates a workflow where you describe what you want, walk away, and come back to find the work done.

The key is safety: always use Git, work on branches, restrict dangerous commands, and review changes before merging. With these guardrails in place, YOLO mode is a genuine productivity multiplier.
