## Useful for

- Train a PPO controller for Go1 on 4096 parallel environments without a GPU
- Run iLQR or predictive sampling MPC for swing-up tasks
- Perform SysID and hardware co-design by sweeping model parameters

## Why it’s here

- 0 stars so far today, about 2 expected by the end of the day.
- The repository is 17 days old and already has 567 stars.
- Recent forks include notable developers: @matheecs (298 followers).

## 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.
