cli-chat-proxy.grok.com started rejecting every request on 2026-10-01
with HTTP 426 "Your Grok CLI version (0.2.120) is outdated. Please
update to version 1.0.13 or later", because x-grok-client-version and
the xai-grok-workspace user agent were pinned to 0.2.120.
Replace the pin with a runtime-published version (built-in fallback
1.0.46) and add a gateway worker, modelled on the Codex profile worker,
that prewarms at startup and refreshes every 3h:
- read the official stable channel https://x.ai/cli/stable, falling
back to npm @xai-official/grok/latest (deployments that cannot reach
x.ai directly), requiring all six platform binaries at one version;
- never roll back, persist the verified version in runtime KV and
restore it on restart;
- AETHER_XAI_CLIENT_VERSION pins a version, and
AETHER_XAI_CLIENT_PROFILE_REFRESH=off disables the network check.
Endpoint header rules still win over the injected identity headers.
