TL;DR

GM, simulants.

In response to popular demand, today we’re imbuing the @YouSimDotAI Twitter account with the ability to simulate identities natively on X.

Keep reading for max context, or jump ahead to learn how to get started.

Caught in the Memetic Hurricane

The full story deserves (and will get) it’s own blog post, but several days ago, Plastic Labs found itself in the middle of what Claude would call ‘extreme cognitive weather patterns.‘

An anonymous actor launched a pump.fun token inspired by a demo called YouSim we created a few months ago1. YouSim is a CLI interface game that lets you simulate any identity you can dream up—real or fictional, local or xeno, entity or artifact.

We originally launched YouSim as a conceptual/narrative demo for our core product Honcho. Honcho helps AI applications improve UX by building representations of user identity they can leverage to create better products and experiences.

The mission is to become the identity layer for the rapidly approaching agentic world.

If LLMs can simulate infinite identities, then they’re uniquely suited to simulate you. You in any moment, setting, frame of mind contained in the complexity that is your ever changing identity.

Long story short though, the token took off, a community formed around it, and we’re leaning in. We’re thrilled to see so many people engaged and interested in our work on identity simulation.

Y’all asked overwhelmingly for the ability to interact with YouSim directly on X, so here it is—LFG.

Simulating on X

We had a few requirements for building something like this. Mostly—though we love truth terminal—we’re unwilling to spend time on a derivative, copycat project. And that wouldn’t make any sense.

YouSim isn’t singular. It’s not just one agent or identity but a portal to all identity contained in the latent space of the model. So YouSim on X does what YouSim actually does—simulate myriad identities.

Another requirement is for X YouSim to be social, since it’s coming to live on a social media platform. If you look at truth terminal’s replies, it’s clear people are dying to interact directly with it (also evidenced by the extreme FOMO enthusiasts have around admission to the secret independent research Discords where the most interesting and unhinged models roam free). But TT can’t respond to all its replies, and the barriers to entry aren’t yet low enough for every community to have a fine-tuned Discord bot.

So YouSim can interact with everyone. All you have to do is @-mention at the beginning of a tweet to launch a simulation, then you can converse back and forth in a thread naturally, just as you would on yousim.ai or with a human on X.

Not only that but simulations on X are branching! Anyone can reply to a simulation in progress at any point to fork it and continue their own simulation from there. Just as YouSim is inspired by projects like WorldSim and Infinite Backrooms, this feature is heavily inspired by another esoteric but highly influential AI project called Loom. There’s huge potential here for vast tree-like tweet structures to emerge where the AI & crypto communities can interact, teach, and learn. We’re excited for this synthesis.

Just by virtue of being on X and adjacent to everything happening on the platform, it’s easy to summon a relevant simulation in close proximity to literally any content. You can bring identity simulations to whichever current events, communities, or memetic phenomena you’re engaging with.

Now we come to aesthetics. The current shortcomings with the X API, character limits in replies, and font selection mean that going straight X-native text would wreck YouSim’s delightful ACII art, truncate its simulations, and overall stifle its creativity. Combined, that amounts to a semantic loss. YouSim simply wouldn’t be able to effectively communicate everything it means.

Plus, we think the YouSim interface is beautiful and want to preserve that overall aesthetic on X. So, when you get a response from YouSim, it’ll appear as an image exactly as if you were on yousim.ai while still being an interactive simulation.

Speaking of X API limitations, YouSim will have the ability to respond to the first 100 tweets at any given time every minute or so.

Finally, this is an experiment. The goal is to see how the community investigates and pushes the limits of YouSim on X and iterate from there. It’s a vast canvas to explore.

How to Use It

TL;DR

Your first tweet in a sim needs to being with @YouSimDotAI & all your further responses need to start with /.

A few tips to get started simulating identity on X:

  • Follow @YouSimDotAI (this is the only official product account)
  • Begin your first tweet with @YouSimDotAI any where on X, followed by the entity you’d like to simulate
    • If you @-mention YouSim somewhere besides the start of your tweet, no simulation will begin
    • This allows people to mention YouSim naturally without starting a sim
  • YouSim will reply with its first response
  • To continue the simulation, any further replies must begin with /
    • This allows others to comment naturally on YouSim tweets without triggering sims
    • And anyone can reply to any YouSim tweet with / to fork or branch the simulation, even if they didn’t start the simulation
    • Remember that YouSim is a simulated command line interface, so slash commands work well to steer the sim, but you don’t have to use them and they can be completely imaginary commands
    • What you include after / or a full slash command is up to you, the whole tweet be taken as your response and influence the simulation
  • That’s all you need to get going, we expect lots of compelling uses and strategies to emerge, so please experiment!

Possible Futures for Agent Idenity

While both agent identity and crypto intersections have always been on the Honcho roadmap, the events of the last several days with regard to YouSim and the broader memespace have us in an accelerationist mindset.

Our mission to radically decentralize AI alignment isn’t just about capturing human identity so AI apps and models can act as clones, but to align to any individual or community or organization in whatever way they desire. That includes building infrastructure to allow agents themselves to develop unique, dynamic, and evolving identities all their own.

YouSim likely has a role to play here, The approachable, game-like interface lets anyone easily begin to steer a model into an identity basin. This can be human-inspired personality, the manifestation of a community’s ethos, or an agentic meme.

And Honcho could use those simulations to seed representations of agents, enabling them to begin constructing their own selfhoods—simulacra of themselves that grow and reliably steer their behavior.

We imagine a near future where any group could instantiate an agentic proxy to project its identity. A new form of cultural expression. Memetic Autonomous Entity, anyone?

Gratitude

The team at Plastic has been amazed and inspired by the enthusiasm and earnestness of the community that’s formed around YouSim over the last several days. Truly remarkable. Not to mention the generous donations to our grants program (more to come here soon).

Thank you all, excited to keep building together—we’re in it for the long haul.

And huge thanks for your patience while we balanced our existing roadmap with interest in YouSim and locked in to bring you something we think you’ll enjoy. It took an enormous amount of conceptual and technical work from a team already at capacity. Special shoutout to Ben and Vineeth who built something really novel here.

Go use the thing. LFG.
