Grok is the xAI surface — versioned models and agent lines; pair with a Bot when the job is fetch-from-second-brain, not casual chat.
Grok (xAI) appears in Yann’s operator stack alongside Claude, ChatGPT, and Gemini (2026-08-19). Grok IV and multi-agent configurations handle labour passes — especially distill and filter steps after capture (Flashcard → Gemini → Grok in the room demo).
When to use
- Second-pass distill when you already structured context upstream.
- Tasks where you want a different model family for challenge or redundancy.
- Operator workflows wired through harnesses — not one-off prompts.
