Weโve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.
This, along with our other recent compute deals, means that weโve been able to increase our usage limits for Claude Code and the Claude API.
Today weโre announcing the full rebuild of our advertising platform, the most ambitious in Xโs 20-year history. This is classic X and xAI: bold, fast, and built for advertisers. Iโm incredibly proud of our engineering team and everyone at X who made this happen. We designed the new ad stack from the ground up for rapid innovation - expect continuous improvements, powerful new features, greater flexibility and better performance. We look forward to working closely with our partners as we roll out this next-generation platform!
The migration in numbers:
- Team of 16 engineers worked over 6 weeks.
- We reduced our footprint from 6M CPU cores, to just 10k cores.
- We are now using the same Grok-based transformer models that power your home timeline.
- Eliminated 15 years of tech debt - replaced 1M LOC of Scala with just 50k LOC of Rust and Python
