Grok (Grok-1)
xAI's first chatbot, Grok, opens in early beta to select US users after about two months of training, with live access to X posts.
A new lab's first assistant, positioned as irreverent and wired into real-time X data. xAI later put the Grok-1 base at 63.2% HumanEval and 23.9% MATH, well below frontier models of the time. Notable mainly for how fast a new lab shipped.

Launch was Saturday 2023-11-04 (article dated 2023-11-06 describes the weekend release). Described by xAI staff as 'the best we could do with 2 months of training'; I did not open xAI's own announcement page, which returned 404.
