Musk says new 2T param Grok model to be trained on SpaceX engineering corpus
Elon Musk@elonmuskSpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run. This will dramatically improve Grok’s engineering capabilities.Cory Robin@flycory11hFor the past few wks since Grok Build launch, we've run SxS testing of complex Codex & Grok Build tasks. Grok Build wins more trust w/ higher accuracy & less hand-holding.
