alakazam · engineAny game, any recorded reality, delivered as a living, playable world model: your data, your weights, running where you want it.
MIRA, the first open multiplayer world model, was released July 6 with code and data by General Intuition and Kyutai. MIRA Mini is our from-scratch reproduction, built in the five days since: the codec, the model, and the four-player fine-tune, served in a browser or downloadable as locally runnable weights.
What that took: five days on rented spot GPUs.
Then we made it fast. A bit-exact port to our FlashDreams runtime runs 2.75× faster on the same GPU. Our own self-distillation campaign is collapsing nine diffusion steps into two, a 330M student and a compact decoder are in training, and a bit-exact MLX port already runs the model on a four-year-old MacBook. A world you own should run where you want it.
Simulation has been a privilege: build an engine, hand-craft environments, or rent metered access to someone else's world. World models collapse that wall: anyone with recordings can simulate and train on their own data.
Ours condition on every participant at once: teammates, opponents, a whole fleet on one floor. Trained on your recordings, the model carries how your people actually behave. That's the part of your world no engine ever had.
The reproduction took days on rented spot GPUs, and the runtime work makes it cheap to serve. The pipeline is amortized; your world rides it. Proven, not promised.
API labs meter imagination, which is ruinous at RL-training scale and impossible where data can't leave the building. We deliver the trained weights on your data, on your cluster if you want. Your simulator is your moat.
“The planet in the glass was never the terrain — it’s the population.”
The agent-training market hand-builds environments at engineer salaries. We turn recordings of play into GPU-batchable, uniform-API environments grounded in how humans actually behave.
Game-agent and QA companies, and studio central tech that already trains replay bots by hand. We are the layer underneath their agents.
Marketing moments now ("play the anniversary, remixed"), and a second life for the replay archive: license your world to the AI-training market, rev-share on data you already own.
Fleets and human-robot floors are multi-agent, which is our native shape. Base models partially serve this lane; the gap is the ops, and delivered weights are the product where data can't leave the building.
Serving is priced in GPU-milliseconds per frame, and the multipliers compose. Measured at the top, in training below:

Success is measured one way: your policy, trained on real plus ours, beats real-only on your own eval.
A pilot starts with recordings. Replays, video with inputs, telemetry, or even a game. You get back a playable world model of your environment, evals against the real thing, and the weights.
