xAI introduced Grok Bot as a task-oriented agent surface rather than another model-only chat entry point.
New Runtime reading: The useful comparison is not model personality but the operational contract: what the bot can act on, how tasks are bounded, which receipts remain visible, and where the user can interrupt or approve work.
Evidence boundary: this item uses the listed public sources and keeps vendor, author, or reporter claims attributed. The queued page is an editorial synthesis, not an independent validation of every reported metric.
