SpaceXSI seeks trillions of synthetic coding tokens with Docker verification

A SpaceXSI mid-training role ties Docker-verified synthetic code to flagship-to-flash distillation and a higher ceiling for later reinforcement learning.

Why it matters

Verified synthetic data at trillion-token scale would give Grok a training supply that SpaceXSI controls end to end, from generation to execution checks. If flagship-to-flash distillation works on that corpus, cheaper models inherit coding skill without flagship serving costs, and later reinforcement learning starts from a higher base.
