## Summary

Musk announced that Tesla will cut the AI5 chip's RAM from 144GB to 72GB and the AI6 from 216GB to 144GB, saying bandwidth is unchanged and the performance impact is negligible, on the grounds that this is the only way to obtain sufficient memory capacity for mass production of the humanoid robot Optimus.
