xAI Takes Vera CPUs for Agents — and Plans a Vera Rubin Rack in Orbit
Nvidia said xAI will deploy Vera CPUs — the 88-core Olympus CPU Nvidia bills as built for agents — to orchestrate Grok’s next agentic workloads, scale Grok infrastructure on Vera Rubin toward gigawatts, and base its first-generation Starmind AI satellite on an optimized Vera Rubin NVL72 rack. No matching x.ai/news post — Nvidia primary is the source. Starmind is planned, not a launch date.
The Grok stack is becoming a full Nvidia factory: Rubin for tokens, Vera for the agent runtime, LPX (separate SKU) for interactive decode — and now a satellite that is the same rack, thermally restated.
NVIDIA newsroom: xAI will deploy NVIDIA Vera CPUs to accelerate orchestration, code execution, data processing, and simulation around Grok agents, keeping GPUs fed. xAI is expanding Grok infrastructure on the Vera Rubin platform as it scales toward gigawatts. Same post: the planned first-generation Starmind AI satellite will be based on an optimized Vera Rubin NVL72. Quotes: Ian Buck (NVIDIA) and Mike Nicolls (xAI president).

What was announced
| Item | NVIDIA newsroom Aug 24 |
|---|---|
| CPU | Vera — 88 Olympus cores; Spatial Multithreading; LPDDR5X up to 1.2 TB/s |
| Claim | Up to 1.8× faster task completion vs x86 on agentic / RL / data-processing mixes |
| Customer use | Agent loop between model calls — tools, code, data, sim |
| Factory path | Grok infra on Vera Rubin, gigawatt-scale |
| Orbit | Starmind gen-1 satellite on optimized NVL72 — planned, not a launch date |
Vera launched as “the CPU for agents” at GTC Taipei (May 31) with xAI already on the exploring customer list. Today is a named deployment + orbital SKU, not a dual-date of the May unveil.
Not August 12 Grok 4.6, not August 19 Build / Bedrock, not August 21 Bot seats / Google Agent Platform, not same-day Groq 3 LPX (inference accelerator, Nebius). CPU vs LPU vs GPU are three sockets.
Limits
- No matching x.ai/news post — Nvidia-only primary.
- Starmind is planned, not a launch window.
- 1.8× vs x86 is Nvidia’s claim on agentic/RL mixes.
- Whether Colossus-class power numbers get attached to Vera Rubin rather than Blackwell is open.
