AI Code Review Action

A GitHub Action that provides automated code review using AI to analyze pull request changes.

Features

• Automatically reviews pull request changes using AI
• Provides detailed code suggestions and improvements
• Adds review comments directly to the PR
• Works with any programming language
• Supports different AI models and API endpoints
• Optional review resolution statuses (e.g., "APPROVE", "REQUEST_CHANGES", "COMMENT")
• Debug mode for enhanced logging

Supported models:

• gpt-4o
• o1
• claude-3-7-sonnet
• claude-3-5-sonnet

My (Subjective) Review of the Particular Models

I’ll grade them on a scale from 0 to 10, where:

• 0 → Completely irrelevant comments
• 3 → My fresh junior/mid-level colleague
• 5 → My mid-level colleague who reads Stack Overflow
• 8 → Me
• 10 → My very smart colleague

So, based on this (highly unscientific) scale:

• gpt-4o → 2
• o1 → 3
• claude-3-5-sonnet → 5
• claude-3-7-sonnet → 6
