How to Automate Code Review with ChatGPT / GPT-4o (OpenAI)
Automate first-pass code review: check for bugs, security issues, style violations, and documentation gaps before human review.
The problem
Senior engineers spend 4-8 hours per week reviewing PRs for routine issues that a machine could catch in seconds.
The outcome
PRs arrive for human review already clean. Engineers spend review time on architecture decisions, not typos and missing null checks.
The tool
ChatGPT / GPT-4o (OpenAI) — OpenAI's GPT-4o is the most widely deployed LLM.
