# xAI Grok 4.20 Non-Reasoning — deprecation status

> No — Grok 4.20 Non-Reasoning is not deprecated as of August 3, 2026. xAI has announced neither a deprecation nor a shutdown date for it.

The straight-through half of the 4.20 snapshot pair, for workloads that want a 1M-token window without paying for thinking tokens. Every previous xAI id with non-reasoning in the name was retired on 15 May 2026 in favour of a reasoning_effort parameter, so the naming here is a step back to an older convention.
