Company details

We are building universe simulations powered by interactive video models.

We train video models that simulate hyper-realistic environments with immersive control, replacing hard-coded game or physics engines with dynamic neural networks.

We built the fastest action-conditioned diffusion video model (running at 20+fps on a 4090 gaming gpu) to simulate minecraft. It is 5x faster than other minecraft World Models and was trained with 100x less resources. Our unique insight was relying on aggressive compression in our tokenizer (128x versus the traditional 8x), and because attention scales quadratically with # of tokens our model can run blindingly faster.

Now we’re training a hyper realistic world model!

Pro

Upgrade to Pro, then request the Lucid teardown.

This company does not have a completed analysis yet. Choose a Pro plan first, then use one of your 5 monthly research requests to have our agent investigate Lucid. The full teardown, rebuild plan, and technical specs unlock when it lands.

  • Use Pro to request the first Lucid teardown and keep the finished report in your account.
  • Read every completed teardown and rebuild plan already in the database.
  • Unlock implementation-ready technical specs and 5 fresh research requests each month.

Choose your Pro plan

$20/ month

Find one worth rebuilding, get the teardown, open the implementation-ready specs, and use fresh report requests when you want deeper research.
