Just jump in.

Build a sandbox, download Codex CLI or Claude Code or whatever and spend some time doing some creative stuff with it just for the sake of learning how it all fits together.

Pay attention to the inputs you provide and the outputs that they result in. Keep your bullshit detector engaged: Bots often lie.

If you get stuck, or it gets stuck, or you want prompting advice or whatever: Ask any frontier-level bot for help. Sometimes, it's very instructive to get help from Claude for an issue with Codex, or vice-versa.

Want better tools? Ask the bot to suggest some that exist. (None of the existing tools fit? Have the bot write new ones.)

All of this stuff is always in a state of flux, so even with the lies they'll do better at teaching than any fixed reference will. They're LLMs and processing language is what they tend to be best at... so go ahead and use that.

And remember: They're designed to behave kinda-sorta like humans, but they are not humans. They're just computer programs. If you don't like their output style, or they don't like your input style: Ask them how to implement rules that make them knock that shit off. :)
