# xAI Grok 4.3 — deprecation status

> No — Grok 4.3 is not deprecated as of August 3, 2026. xAI has announced neither a deprecation nor a shutdown date for it.

The workhorse of the xAI API and the destination for seven of the eight ids retired on 15 May 2026. It takes a reasoning_effort setting rather than splitting reasoning and non-reasoning into separate model names, which is the change that made half of xAI's catalogue redundant in one release. A million tokens of context at $1.25 per million in.
