In Depth
Claude Code
Claude Code is a terminal-based coding agent from Anthropic. You give it a prompt, and it reads your codebase, plans changes, edits files, runs tests, and commits - all autonomously. It spawns sub-agents for parallel work, uses persistent memory (CLAUDE.md files) to remember project context between sessions, and integrates with MCP servers for external tools. I run it on the Max plan ($200/mo) and it handles everything from multi-file refactors to full feature builds. My video on Claude Code sub-agents hit 160,000 views - it's the tool my audience asks about most. The latest version uses Claude Opus 4.6 under the hood.
OpenAI Codex
Codex is OpenAI's autonomous coding agent, accessible through ChatGPT. It clones your GitHub repo into an isolated cloud container, reads the codebase, and executes multi-step tasks - writing code, running tests, and creating pull requests. Because it runs in a sandbox, it can't accidentally break your local environment. It uses the codex-mini model (based on GPT-5.3) optimized for code. My Codex video hit 216,000 views, making it one of my top 5 videos of all time. I use it with the `codex exec` CLI for headless automation.
