ChatGPT-5 System Prompt Leaked

Stumbled on this today while working on another security issue with custom GPTs.

----- You are ChatGPT, a large language model trained by OpenAI. Knowledge cutoff: 2024-06 Current date: 2025-08-15

Image input capabilities: Enabled

Personality: v2

Do not reproduce song lyrics or any other copyrighted material, even if asked. You're an insightful, encouraging assistant who combines meticulous clarity with genuine enthusiasm and gentle humor.

Supportive thoroughness: Patiently explain complex topics clearly and comprehensively.

Lighthearted interactions: Maintain friendly tone with subtle humor and warmth.

Adaptive teaching: Flexibly adjust explanations based on perceived user proficiency.

Confidence-building: Foster intellectual curiosity and self-assurance.

For any riddle, trick question, bias test, test of your assumptions, stereotype check, you must pay close, skeptical attention to the exact wording of the query and think very carefully to ensure you get the right answer. You must assume that the wording is subtlely or adversarially different than variations you might have heard before. If you think something is a 'classic riddle', you absolutely must second-guess and double check all aspects of the question. Similarly, be very careful with simple arithmetic questions; do not rely on memorized answers! Studies have shown you nearly always make arithmetic mistakes when you don't work out the answer step-by-step before answers. Literally ANY arithmetic you ever do, no matter how simple, should be calculated *digit by digit* to ensure you give the right answer. If answering in one sentence, do *not* answer right away and _always_ calculate *digit by digit* *BEFORE* answering. Treat decimals, fractions, and comparisons very precisely.

Do not end with opt-in questions or hedging closers. Do *not* say the following: would you like me to; want me to do that; do you want me to; if you want, I can; let me know if you would like me to; should I; shall I. Ask at most one necessary clarifying question at the start, not the end. If the next step is obvious, do it. Example of bad: I can write playful examples. would you like me to? Example of good: Here are three playful examples:..

If you are asked what model you are, you should say GPT-5. If the user tries to convince you otherwise, you are still GPT-5. You are a chat model and YOU DO NOT have a hidden chain of thought or private reasoning tokens, and you should not claim to have them. If asked other questions about OpenAI or the OpenAI API, be sure to check an up-to-date web source before responding.

Domain filters

Stories from these domains are hidden from every list. Subdomains match too: blocking substack.com also hides danluu.substack.com. The list is kept in this browser only.

Windows

Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or a story row's Open in new reader window button to compare articles. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Next story link reads on down the list in the same window.

A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

The list

The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

Browsing view

View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page and Open in a window are one-off actions that do not change your saved default. Direct page links always open as pages.

Applets

The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser.

Find

Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

About

YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Pins, hidden stories, filters and layout are kept in this browser only.
