What Grok 'knows'

• Training — statistical patterns in a huge corpus, frozen at a cut-off (for Grok 4.6, early 2026). Good for widely documented knowledge. Bad for your internal wiki.
• Context — everything in this request: system prompt, your paste, prior turns, tool results. This is the only place your private facts should live.
• Retrieval — DeepSearch or your own tools. Fresh, but only as good as the pages fetched and the reading of them.

If a fact is not in one of those three places, Grok may still say it. That sentence will be a guess wearing a suit.
