A text adventure that thinks faster than you read

Here's the idea in one line: a text adventure where you type what you do, and the game instantly writes what happens next. The whole world is one long conversation with a model. You're the hero, it's the narrator.

Why this only became possible now

You could have built this game before. But it killed itself on the wait: you'd type a move, then stare at a blinking "…" for ten seconds while the model thought. Any bit of magic evaporates in that gap.

On July 9, GPT-5.6 shipped. Its top model, Sol, runs on Cerebras chips at around 750 tokens per second — roughly 10× faster than an ordinary GPU. In practice that means one thing: the new scene shows up faster than you finished reading the last one. "Loading…" disappears. And that's exactly when the story stops being a chat with a bot and starts feeling alive.

Speed here isn't just "nice." It is the feature the whole thing is built around.

What you'll learn

• Streaming a response. Text arrives piece by piece and types out in front of you, instead of landing as one block after a pause.
• The prompt as the game engine. The world, the rules, and the memory of your actions all live inside the conversation with the model — that's basically the whole "game code."
• Playing the host. The system prompt sets the game master: the tone, how strict the rules are, how many options to offer per turn.
• A tiny interface. An input box, a story feed and three choice buttons — you don't need more.

A ready starter prompt

Don't ask the agent to "make a text game" — you'll get a faceless chat. Describe the game master, the memory and the turn format:

The strong prompt turns the model from a chatty bot into an actual host: the role, the memory, the turn format and streaming are all set. The game plays right away, instead of "almost working."

What you end up with

You type "I walk into the tavern" — and the text pours out at once: the creak of the door, the smell of ale, the hum of voices, three things you could do. Ten turns later the bartender still remembers you promised to return his sword. Every new run is a different world: a dungeon today, a space station tomorrow. All of it on one screen and one stream from a model.

Start with the simplest move — "you're standing at the castle gate." The moment you see the answer pour out with no pause, you'll want to add rules, enemies and endings yourself.
