## Useful for

- Run simulate to interactively inspect and debug a robot model
- Train a locomotion policy via differentiable physics in MJX with JAX
- Build an LQR controller balancing a humanoid on one leg

## Why it’s here

- Star-counter measurements on 2026-10-10 (UTC), 11:30–12:58: 15578 → 15579 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +9 stars, using observed gains and the previous day.
- GitHub Trending C++ today: #12, +28 stars.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
Data as of 2026-10-10 13:04 UTC, updated every 30 minutes.
