| Sharing a little open-source game where you interrogate suspects
| in an AI murder mystery. As long as it doesn't cost me too much
| from the Anthropic API I'm happy to host it for free (no account
| needed).
|
| The game involves chatting with different suspects who are each
| hiding a secret about the case. The objective is to deduce who
| actually killed the victim and how. I placed clues about
| suspects' secrets in the context windows of other suspects, so
| you should ask suspects about each other to solve the crime.
|
| The suspects are instructed to never confess their crimes, but
| their secrets are still in their context window. We had to
| implement a special prompt refinement system that works behind-
| the-scenes to keep conversations on-track and prohibit suspects
| from accidentally confessing information they should be hiding.
|
| We use a Critique & Revision approach where every message
| generated from a suspect first gets fed into a "violation bot"
| checker, checking if any Principles are violated in the response
| (e.g., confessing to murder). Then, if a Principle is found to be
| violated, the explanation regarding this violation, along with
| the original output message, are fed to a separate "refinement
| bot" which refines the text to avoid such violations. There are
| global and suspect-specific Principles to further fine-tune this
| process. There are some additional tricks too, such as distinct
| personality, secret, and violation contexts for each suspect and
| prepending all user inputs with "Detective Sheerluck: "
|
| The entire project is open-sourced here on github:
| https://github.com/ironman5366/ai-murder-mystery-hackathon
|
| If you are curious, here's the massive json file containing the
| full story and the secrets for each suspect (spoilers obviously):

| This is a really fascinating approach, and I appreciate you
| sharing your structure and thinking behind this!
|
| I hope this isn't too much of a tangent, but I've been working
| on building something lately, and you've given me some
| inspiration and ideas on how your approach could apply to
| something else.
|
| Lately I've been very interested in using adversarial game-
| playing as a way for LLMs to train themselves without RLHF.
| There have been some interesting papers on the subject [1], and
| initial results are promising.
|
| I've been working on extending this work, but I'm still just in
| the planning stage.
|
| The gist of the challenge involves setting up 2+ LLM agents in
| an adversarial relationship, and using well-defined game rules
| to award points to either the attacker or to the defender. This
| is then used in an RL setup to train the LLM. This has many
| advantages over RLHF -- in particular, one does not have to
| train a discriminator, and neither does it rely on large
| quantities of human-annotated data.
|
| With that as background, I really like your structure in AI
| Alibis, because it inspired me to solidify the rules for one of
| the adversarial games that I want to build that is modeled
| after the Gandalf AI jailbreaking game. [2]
|
| In that game, the AI is instructed to not reveal a piece of
| secret information, but in an RL context, I imagine that the
| optimal strategy (as a Defender) is to simply never answer
| anything. If you never answer, then you can never lose.
|
| But if we give the Defender three words -- two marked as Open
| Information, and only one marked as Hidden Information, then we
| can penalize the Defender for not replying with the free
| information (much like your NPCs are instructed to share
| information that they have about their fellow NPCs), and they
| are discouraged for sharing the hidden information (much like
| your NPCs have a secret that they don't want anyone else to
| know, but it can perhaps be coaxed out of them if one is clever
| enough).
|
| In that way, this Adversarial Gandalf game is almost like a
| two-player version of your larger AI Alibis game, and I thank
| you for your inspiration! :)

| This just clearly isn't true. You cannot clear and purge

| The human using the AI can take that text anywhere and do

|
| One interesting difference here is that it's directly
| using the supplied game interface to exploit the game.
| And in a way, it's precisely following the game
| instructions, too -- ask clever questions to figure out
| what happened. So in some ways the game ends up feeling
| like a half-baked experience with poorly thought out
| boundaries, rather than me cheating.
|
| That said, the instructions do say that I'm supposed to
| roleplay as Detective Sheerluck.
|
| I do find it interesting that it's entirely up to me to
| keep the experience functioning. Very much the opposite

| break! But wait, the instructions for this hypothetical
| platformer say you're supposed to be in a realistic
| environment, and clearly jumping that high isn't
| realistic, so I must be cheating... or maybe the jump
| button just needs more work.
