Users report sudden shift in Grok bot quality, suspect a hidden model swap
alexcovo_eth · x · 2026-10-29
A user on X reports that their Grok bot seems to have suddenly degraded from "Opus 5.5"-level performance to something like "Grok 4.7": weaker reasoning, more errors, and notably worse instruction following. They asked whether others noticed the same shift.
This is community speculation about a silent underlying-model swap, unconfirmed by xAI.
