Video

Motion and continuity that hold across every frame.

Real workloads & feedback guide the next training cycle.

Better with every cycle.

We use feedback from real-world work to guide post-training, then evaluate the updated model on your tasks before deployment.

1

Use & Feedback

Define your use case, data, and success criteria.

2

Post-train

Adapt the model to your target behavior.

3

Test & Validate

Test on the tasks that matter to you.

4

Deploy & Learn Again

Use the model in real workflows and learn what to improve.

All under one roof.

Post-training is half the job. We also run the model ourselves, so nothing is handed off to another company.

Run in Japan

Your model runs on GPUs we own and operate in Japan, behind the same API as every model we serve.

Tested before we train

We test the model on your tasks first, then train it on the ones it solves about half the time.

Yours to keep

The model stays yours, from post-training through production.

Shape a model around your work.
