## Summary

X Square Robot has released X2Real, an evolvable simulation evaluation benchmark. Its simulated evaluation and real-robot evaluation achieve a task success rate correlation of 0.96 and a progress score correlation of 0.99.

## Why it matters

It provides correlation data between simulated and real-robot evaluation along with a unified integration method, allowing readers to judge whether simulated evaluation can replace part of real-robot testing.
