→Grok keeps updating after xAI disbandment as Musk announces a new model
Elon Musk said the 1.5T-parameter Grok V9-Medium has finished training, will enter reinforcement learning in a few days, and is planned for release in two to three weeks. Grok Build supports up to 8 parallel sub-agents, a 256K-token context window, Plan Mode, Arena Mode, MCP, and ACP.

why featured
HKR-H/K/R all pass, but this is a Grok V9-Medium preview before RL and release, with no benchmarked capability yet. That fits a strong model-race/product update at 82, featured but not p1.
editor take
xAI may look dismantled, but Grok is shipping a 1.5T model plus a coding agent; this smells like Musk-style churn, not retreat.
sharp
xAI is not proving Grok survived; it is trying to buy its way out of weak coding performance with Cursor data. Grok V9-Medium has finished training at 1.5T parameters, triple the 0.5T v8-small serving production traffic, with RL starting in days and release claimed in two to three weeks. That gives practitioners a clean verification window.
I have doubts about the “$60B right to acquire Cursor” claim, because the snippet gives no deal terms or data-license boundary. Grok Build now runs grok-code-fast-1, with 256K context, 8 sub-agents, Plan Mode, Arena Mode, MCP, and ACP. The feature sheet tracks Claude Code closely. The missing pieces are SWE-bench, real-repo pass rate, and long-horizon task retention. Without those, 1.5T is compute theater; Cursor workflow data is the actual asset.
