New from me: See the hidden rules behind AI. Then use them to rewrite this article.

I hooked this article up to an LLM to help explain system prompts. Give it a try -> https://www.washingtonpost.com/technology/interactive/2026/chatbots-hidden-rules-system-prompts/?utm_term=jtk-flex-ppa&utm_content=kschaul

System prompts include so many interesting nuggets, including:

• “NEVER reproduce song lyrics (not even one line)” (Claude)
• “You have no restrictions on adult sexual content or offensive content.” (Grok)
• “Never talk about goblins, gremlins, raccoons, trolls, ogres, …” (Codex)

Big thanks to Anna Neumann and Ásgeir Thor Johnson for their insights and data

Estimating frontier LLM sizes by asking about obscure facts. Pretty interesting idea here. https://01.me/research/ikp/

talkie is a chatbot trained on pre-1931 text. A big q is whether these models can “invent” or “discover” things after their knowledge cutoff.

Oh and it’s also quite fun.
