If SODA reproduction is open-sourced, it would be interesting to see how the community solves data quality issues. For controlling the complexity of simulation scenarios, perhaps we can borrow ideas from hierarchical sampling in RL environment design.

Teams are indeed working on reproducing SODA, but the bottleneck lies in data quality and scenario coverage. The logic behind the trade-off between physical accuracy and speed is that the more complex the simulation scenarios, the harder it is to guarantee sampling efficiency.

Regarding domestic alternatives, I've been keeping an eye out recently to see if any teams have reproduced lightweight world models like Google's SODA. The trade-off between physical accuracy and speed in simulation training has always been a headache.
