# xAI Grok 4.5 — deprecation status

> No — Grok 4.5 is not deprecated as of August 3, 2026. xAI has announced neither a deprecation nor a shutdown date for it.

xAI's current flagship, with a 500k context window and a February 2026 knowledge cutoff. It is worth noting that it is not the model xAI routes retired ids to - that is grok-4.3, which has double the context and costs less. 4.5 is a deliberate choice rather than a default you fall into.
