CodeRabbit's Growth Story
- CodeRabbit started as an internal tool and grew independently into an AI code review startup.
- It now has over 100,000 daily users and spans various industries.
Deep Reasoning with Sandboxed Agents
- Code review requires deep reasoning and can tolerate latency unlike code generation.
- CodeRabbit uses sandboxed environments where AI agents run CLI commands to dynamically explore code.
Optimize Multi-Model Pipelines
- Use an ensemble of multiple models optimized for different pipeline stages.
- Employ cheaper, faster models for summarization and expensive reasoning models sparingly for cost efficiency.
