Elon Musk anticipates significant performance improvements for Grok within approximately three months. These gains are expected to stem from a complete rewrite of the training and inference stack in C/C++, which will involve substantial simplification and the removal of many software layers. Additionally, Grok will be optimized to work exceptionally well with the GB300 hardware. AI

IMPACT Optimizing AI training and inference stacks with languages like C/C++ could lead to faster and more efficient AI model development and deployment.

RANK_REASON Elon Musk's statement is a commentary on future infrastructure improvements for Grok, not an official release or product announcement.
