    Feels like a scene from Douglas Adams' B Ark.

      Exactly what I was thinking reading through this. This is amazing and also frightening and hilarious. It’s like a deformed version of how normal groups of humans would operate. Very rules and process-oriented humans. I found the no-blame inquiry into chicken tossing that resulted in what is effectively written law particularly striking, and adorable, and depressing. And cute.

    This is hilarious and adorable.

    > "Ada tossed a cooked chicken to Noor; Esme picked it up by accident and ate it. A three-minute "no blame" inquiry produced a written protocol..."

    They're like super-serious little senior engineers. (edit: or dining-philosophers).

    About how much KV cache do these kinds of agents use? Could you squeeze 50 of these $game agents onto a small consumer GPU (small LLM)?

    Idly imagining a game server of some kind with a bunch of human friends sharing one person's GPU, with a flock of agents colocated on it.

    People have done experiments like this before.

    Minecraft isn't a intelligence problem. An LLM is more than smart enough to play Minecraft. It's a robotic problem. Even a normal human player can click several times per second, can press two different buttons at the same time, etc. Mineflayer gives you an API that is more limited than a human in some ways (can't see far away from you) and less limited in others (can see through blocks) (if I remember correctly, I could be thinking of Baritone or a different project). Robotics or playing a video game requires a tight continuous feedback loop. When there's 500ms of latency in order to ask the model for every mouse movement, it's no wonder fighting a spider is scary.

    Fun fact, Mineflayer, the Minecraft bot interaction API used by YCombinator for these tests, was originally developed by Andrew Kelley (before he started Zig).

      The human body has the ability to automate some muscular movements so the brain is out of the loop. Maybe these LLMs should be allowed to write in a small DSL that can trigger events out-of-band (something like "Oh fuck there's a spider, I'll set up a click spam loop and check in every 500ms").

    Interesting setups, I found the Minecraft agents to work in an almost turn-based manner, which makes me think that the three hours and open format did not really give them sufficient incentives to play in a more lively or reactive manner. On the other hand, they also behave similarly in Bed Wars, which should have incentivised it. A bit disappointed...

    I'm also wondering if the article itself was generated by agents too, in a "here are the logs, clip interesting moments thx" manner by the authors. It's got a certain disinterested and distracted style to it.

      I think big reasoning LLMs are just the wrong architecture for live games like this, latency is going to be crap given that every token requires an entire forward pass through the model.

      Card games or turn based strategy are much better suited.

    I am more impressed by the embedded gameplay widget. Does anyone know what tool/library is that? That'd be so cool if I am able to showcase my worlds on my blog posts!

    As impressive as this is, I can't help but conclude that the need for agents to write JavaScript programs to act out their actions represents a considerable limitation in current AI reasoning.
    • NickNaraghi 9 minutes ago
      On the contrary, having the intelligence write deterministic code that saves time and lowers error rate seems like a winning approach.
      • JBits 2 minutes ago
        It demonstrates that current LLMs are completely unable to follow a simple series of logical tasks. I feel the same way about ARC-AGI 3. While it might be the winning approach today, if they need this amount of complexity to do something simple, then it shows that their ability to generalise is clearly limited. Mining ore in Minecraft shouldn't be such a challenge for LLMs and yet it is!

    Are there people playing AI + human vs AI + human games? I think it might be fun to play an RTS against someone where the only rules are no hacking the game itself, but writing harness, macros, any kind of stack is allowed.

      https://olamarena.com/ is sort of this but not with full code manipulation like you describe

      there is screeps, but afaik it's purely scripted with no "live" human playing

    We need LLMs performing actions in nano seconds so it can run every game tick. 3 to 5 years I think.
    • NickNaraghi 8 minutes ago
      Jev and the fast-follow models seemed to be useful in this direction.
    • ivanjermakov 48 minutes ago
      Game tick is usually 16ms, so a nanosecond latency is 7 orders of magnitude faster than needed.
      • CyborgCabbage 10 minutes ago
        Minecraft runs on 20 ticks per second so 50 ms

    this is amazing wow

    Its a little disappointing they have a hierarchy based purely off alphabetical order, i wonder if a slight difference like a different skin or personality system prompt like [45% Extrovert 55 introvert, 20% caustion 80 bold...] could introduce some politics

    Outside of the content, I'm so bored with this web design trend. Gwernslop is what I've started calling it.
    • andai 1 hour ago
      What is the relation between this design and gwern's?

      My observation: article is not serif, not book length, and doesn't take a minute to load on my phone. Gwern rating 0/3 :)

      (Also missing: the essential one billion footnotes!)

    • bstsb 1 hour ago
      grrrr, i hate grayscale backgrounds and simple fonts!

      would you rather claude-esque purple gradients and glowing borders?

      • Avicebron 1 hour ago
        No? There is originality between a fetishization/bastardization of minimalism on one side and cookie cutter LLM web design on the other.
        • epestr 1 hour ago
          Is there a trend in increase of minimalistic website which are LLM generated and explicitly made minimal to not seem sloppy?
          • Avicebron 1 hour ago
            idk, you tell me, I can tell from your blog that you've adopted the trend. I'm probably much older than you, so I've seen the progression of these things since the internet as we know it existed. So I sort of understand the roots of the styling that people are adopting and can see it for what it is, which is trying to signal a minimalism but missing the point in the process.
            • epestr 13 minutes ago
              I was quite inspired by the content bar of this site: https://zachlandes.com/trolley-problem and gwern. Though I do think my blog isn't particularly all that minimal I try to add a lot of colors to make it look less dull.

              Their website is great, and they’re a student. Back in my day, we supported younger people in the industry regardless of whether they met our personal aesthetic. We used to call that ‘maturity’.

          I get that you’re angry, but could you try that one again? It doesn’t make sense.

      It's pretty much an immediate Firefox Reader Mode toggle for me.

      I am incredibly bored with this "everything I don't like is slop" trend
