AI Models Guide
Git AutoReview supports Claude, Gemini, and GPT. Choose the right model for your code review needs.
Claude (Anthropic)
Catches complex logic issues and gives detailed, specific feedback
Strengths
- Reads across files, not just the diff
- Detailed feedback with file-level context
- Good at spotting security issues
- Handles complex logic well
Considerations
- • Slightly slower than Gemini
- • Higher API cost
Best for: Thorough reviews where a few extra seconds don't matter
Gemini (Google)
Fast, handles large PRs well thanks to 1M token context
Strengths
- Very fast response times
- Large context window (1M tokens)
- Good for large PRs
- Cost-effective
Considerations
- • Less detailed than Claude on tricky logic
- • Can miss edge cases
Best for: Large PRs or when you need results fast
GPT (OpenAI)
Widely used, works well for most review tasks
Strengths
- Predictable output format
- Reliable results across languages
- Solid all-around reviewer
- Works with OpenAI-compatible tooling
Considerations
- • Can be verbose
- • Rate limits on free tier
Best for: Teams already paying for OpenAI API access

Frequently Asked Questions
Which AI model should I use for code review?
Start with Claude if you're unsure — it tends to give the most detailed feedback. Use Gemini for large PRs or when speed matters. Use GPT if your team already pays for OpenAI API access.
Can I use multiple AI models?
Yes. Git AutoReview supports Dual-Model mode — run two models on the same PR and compare their suggestions side-by-side. Useful for important reviews or when you want a second opinion.
Do I need API keys for all models?
No. You only need an API key for at least one model. You can add more later. Each model requires its own API key from the respective provider.
How much do the AI models cost?
Costs vary by model and usage. Claude: ~$3-15/million tokens. Gemini: ~$0.50-7/million tokens. OpenAI: ~$2.50-30/million tokens depending on model. A typical PR review uses 10-50K tokens. With BYOK, you pay the provider directly.
