Catch your AI up

Every AI model stops learning at its training cutoff. It doesn't know anything that happened after that date, and it may call recent news fake. Each briefing is a sourced summary of what the model missed.

1. Find the AI you use in the table below. The briefing links are listed next to it.
2. Copy the link. "Short" fits every chat. Use "full" if your AI can read long files.
3. Paste it into the chat, for example: "Here is a sourced summary of AI news after your training cutoff: [link]". If your chat has web search, turn it on so the model can check the sources.

Not sure which model you're using? postcutoff.com/ai covers everything since July 2026 and works in any chat. Models are often wrong about their own cutoff, so if you're unsure, pick an earlier month.

Or pick by cutoff month

If you know your model's training cutoff, use the same month or the nearest earlier one.

For agents and developers: the same list as plain Markdown is at briefings/README.md. Why this matters: models calling real news fake.
